service light and wrench?

[Rivernut]

My '03 Vue has the service light with the wrench icon turning on everytime it is driven. The light shuts off when the ignition is turned off. Driving the car even ten feet triggers the light. The vehicle drives great with no outward signs of a problem. It is an AWD V6 with 124,000 or so miles. I read somewhere that the service wrench light codes can only be read at the Saturn dealers. What likely is going on and what should I do?

[fdryer]

A recent member bought a more expensive (<$300) reader/scanner and posted SES along with wrench codes, proving that wrench codes can be read by better scanners. The trick is to find a local shop that can read GM/Saturn wrench codes. You may have to call round before finding anything otherwise Saturn it.

[Rivernut]

why the two groups codes? What kinds of issues are among the possibilities?

[Ritz]

Obviously, the ECM thinks something is wrong. Instead of waiting for that warning to be translated into something that has already broken, why not just waddle in to any Autozone and ask them to scan it for you? They'll do it for free. Then come back with the actual trouble code. Perhaps then, you'll get some helpful responses. Driving it around that way is just not a very clever thing to do. Look into it now instead of waiting for the inevitable smack in the back of the head when something breaks. :)

The two separate groups of codes are simply because every vehicle manufacturer must maintain accepted OBD I or OBD II standard codes. The other codes are termed wrench codes; these codes are manufacturer specific so they're called wrench codes. This is to separate Ford's, M-B's, Jaguar's, etc., from Saturn's codes. Its a way to individualize certain issues unique to each car manufacturer that doesn't apply to the other manufacturer. The key to knowing generic SES codes from wrench codes is that the second digit after 'P' separates SES standardized codes from wrench codes. P0xxx is for standard universal service engine soon (SES) codes every manufacturer abides by while P1xxx are the wrench codes each manufacturer creates for themselves. This then becomes a problem because general readers/scanners cannot read wrench codes so we have to pay more for better readers/scanners if we want to read the wrench codes. Its spelled out in each description of these scanners or conveniently left out as most DIYer's don't know about wrench codes being separate from standard codes.

You can see the different wrench codes (P1xxx) in the How-to library on page 6 under OBD II Powertrain Codes. There will be a long list of regular generic codes (P0xxx) followed by the wrench codes (P1xxx).

[Gerry Proctor]

why the two groups codes? What kinds of issues are among the possibilities?

There are actually four code groups: P=powertrain; B=body; C=chassis, and U=network.

Within those groups it further breaks down as you go along the numeric component. A zero following the alpha prefix is a generic code (P0XXX). A 1 following the alpha is a manurfacturer-specific code set (P1XXX). (example: P0300 is an OBDII generic random misfire code and will always mean the same thing regardless of manufacturer) P-Zero(xxx) codes will set the check engine light (the engine icon, or MIL) since they are specific to emission equipment malfunctions. P1, and all B, C, and U codes will usually set the wrench icon light since they are not usually related to emission manlfunctions, though some P1 codes can set the MIL since they may have an OBDII component. Also, P1, B, C, and U codes are specific to at least a manufacturer and many times to a specific car and they get more precise by that car, that year, with that powertrain. There is no universal interpretation for anything but the OBDII P0XXX codes.

There can be literally many hundreds of possibilities so without a proper scanner and software to read and interpret the code(s) it is impossible to guess.

You can look this up online to get a better understanding of the codes and how they do (or in some cases, do not) speak to you.

[Rivernut]

I was on the way to Autozone, but decided to call them first. The guy said that his scanner probably would not read a service wrench light. He thought it would only do engine SES codes. I'll bring it there and try in case he's wrong. Would it be so hard for an onboard computer to say a little more instead of secret codes? You shouldn't need a reader, it should just announce the perceived problem using 10 year ago technology. I know they make money this way be keeping it cryptic.

[slothy]

if not maybe take it to a garage and throw a few bucks at them to have them use their scanner.

[fdryer]

Actually it can go one of two ways; if it were that easy to simply have a display to show the codes in each car, we'd probably pay more for this. These codes were not derived for the average person to understand and follow up on but were for the dealer trained service people with technical skills to use the sophisticated GM Techtool II equipment that does far more than the cheap scanners do. As you know, nowadays a dealer trained mechanic cannot just know something but must have electronics training as most cars are driven by electronics. A higher skill set is needed now more than ever. The education required is needed to use and understand the very sophisticated equipment used at the dealer level as well as at the local garages since portable less expensive readers/scanners are available for the commercial repair shops. We as the end product users of our cars can either buy the less costly but very basic readers or pay a little more for the ability to read the wrench codes. That's just the way it is and it won't change anytime soon. The wrench codes along with the SES codes were designed for access by almost anyone with the abilities to use more sophisticated equipment but at what cost? I'm still deciding on what I may need to read/scan my car but I would also like the capability to read/scan a Nissan my sister has but wrench codes are different for each car so more money has to be spent for the ability to be compatible with other manufacturers. This leads to equipment costing more than necessary so a line is drawn at the dealer level; SES codes read by any scanner, wrench codes read by more expensive scanners and the very expensive dedicated GM or Ford or Toyota, etc. equipment for the dealer techs to use. Not everyone wants or can understand how to use a display that will tell them codes. Ever read of posts that are simply answered by reading the owner's manual?

[Rivernut]

I took it to Autozone today after driving it about 80 miles without the service light triggering. Yesterday it did it everytime it was started, today nothing. No codes showed on the Autozone scanner. What's up with intermittent service lights?

[Rivernut]

Do any non-Saturn code readers have access to service "wrench codes"? I don't want to spend $90 to find out that I have something non critical.

[Gerry Proctor]

Sure. SnapOn Modis, OTC Genesys are the two most common shop scanners.

[Rivernut]

the Vue had been showing the intermittent service wrench code with nothing other than flashing the ABS twice. I was going to take it to the vocational school where I work and check it on their scanner today. Last night my wife took it out to run errands and the dash lit up with the service, ABS, and SES. Also the gauges were all going crazy, bouncing up and down - gas tank full...gas tank empty...tach up and down...speed up and down. She said it drove fine though. My guess is either the alternator is dieing or there is a short somewhere. I'm going to check the voltage and charging system with my diagnostic digital battery charger. I am assuming that the SES light is probably from low voltage to one or many sensors. Any ideas besides getting hooked up to a proper code reader?

[fdryer]

Possibly the beginnings of BCM failure, displaying the 'possessed' characteristics?

[burnout]

This thread is very helpful for learning about the different categories of codes, be it SES or "Wrench." Is there a FAQ it could get thrown in?? :hammy:

I did not want to take it to work today to have it looked at because I was afraid it might die on the way (80 mile round trip) with some spooky electrical issue. I started it this morning out of curiosity and no bad lights came on. My wife said the dash was lit up for 30 minutes on the way home last night. I took it to Autozone again since the SES light had come on, and nothing. Minutes later on the way home three lights came on. The service wrench light came on and stayed on. The ABS light and brake light kept turning on and staying on for several minutes each, not corresponding to any braking that I was or was not doing. It got more frequent the more I drove. It gets worse as the temp climbs I guess, common with electrical issues. When I got home I checked the connections on the battery and fuse panel under the hood. They were fine. I hooked up my digital charger and put it on alternator check mode and it showed 100%, and 97% with the lights on. The AC Delco battery is showing green, no other sign of electrical deficiency with everything turned on at once. This same Vue had the V6 engine go (oil pressure lost to top of engine) at 100,000 miles for no apparent reason despite being babied and fed Mobil 1. I am not impressed with this SUV. At least I got the GM discount through my father in-law. I'll bring it to work tomorrow, then to the local Saturn specialty shop, then to Saturn if forced to, unless someone here comes through for me. I seem to be blazing the bad luck trail with my high mileage Vue.

[Rivernut]

The code reader at school showed three faults in the network. ABS and two others that I was told go through the body module. What are the symptoms of a bad body module? Are they expensive? Is it common for these to go bad?

[fdryer]

All the symptoms you described and more, as posted by early Vue and L-series owners until the Passlock anti-theft system becomes enabled preventing you from disabling it to start and run the engine, usually resulting in a tow to the dealer. Sometimes the lights and horn blare away as its towed away unless the battery is disconnected.

No specific codes to post? Any faults associated with the ABS unit would normally trigger the ABS indicator while simultaneously disabling it with no effect on normal braking. This and the two other codes may be the wrench codes you said lit up the wrench indicator. Too bad you weren't able to retrieve the codes for posting and look up. All the BCM does is act as the diagnostics center to retrieve information from the ECM, TCM, and its own subsystem to transmit SES and wrench codes to the OBD II connector as well as act as the conduit for Saturn's Techtool II to perform extensive diagnostics such as exercising the ABS individual valves, check and monitor various signals and programming for any updates necessary as changes occur. The Passlock anti-theft system resides in the BCM so replacement also means programming the new one to match communication protocols crucial to enable synchronizing the three mini-computers otherwise simply dropping in any BCM just won't work. VIN, mileage, accessories have to be enabled/disabled as part of programming a replacement BCM. Replacement costs range between $400-$600 or so. Look up past threads about BCM failures. It seems that BCM failures occurred in the early models and lessened as time progressed and other models added, like the Ions and Sky's.

[Rivernut]

I asked the kid working on it to write it down or print it out and he didn't. By the time I got back down there everyone was gone and I drove it home. On the 40 minute drive home the wrench code came on, but no others. I'll ask them tomorrow for the specific codes.

[Rivernut]

Here's the update. The code reader at my school showed lack of communication with power steering, SIR/SDM, and IPC. The codes numbers v1648, v1088 and v1096 were written by the tech with them. The car runs great. No service lights at start-up. Ten to fifteen into highway driving the service wrench light appears. Twenty minutes into the drive the ABS and brake lights join in. Thirty minutes into the drive the fuel gauge, speedometer and tachometer fluctuate from the correct value to zero. Somewhere in the mix the odometer light turns off. This Vue never had any electrical issues and is totally stock with nothing aftermarket added such as stereo or alarm. Does this sound like a defective body control module? If it is the BCM, can I replace it myself and drive it to a Saturn dealer for programmig or would it not start or be driveable?

It's the BCM. I've never replaced one on a VUE so perhaps someone else here can chime in on the difficulty level.

Just a thought - my car was acting like the devil with the gauges for quite a while, in and out of the shop, it was a nightmare -

All it was, was the ground wire to the main computer wasn't correctly attached and it would cause it to bounce on and off apparently. Sneaky little devils. Something as easy as cleaning and reattaching the wires completely alleviated the problems. But, since it took the shop a week + to get the vehicle to act up, it ended up costing me $250 for a simple fix.

Hope this steers you in the right direction.

[verucalise]

ALSO- My shop ended up attaching this flight computer diagnostic to my car, because it would only act up with lights on during a drive, and I gave the shop manager permission to driver the darn thing around until it acted up. It sometimes took 30-45 mins straight of driving before it would act up, but the flight computer worked like a charm. My car would have intermittent driving difficulty, but almost 100% of the time my speedometer would go absolutely NUTS and my steering would be jerky, like it didn't know how fast my car would be going. At one point, I went out in the cold to start my car and let it warm up for my kids, and went back inside. Since my car automatically locks when I hit like 8-10mph - my speedometer started jumping and locked me out of my car! You could look into my car, while it sat idling, making no noises or anything - but there's my speedometer saying I'm going 110--no, 20,--- now 50.... it was hysterical.

[Rivernut]

I checked and cleaned the battery terminals and the positive lead to the underhoid fuse panel. This had no effect on the crazy dash lights and gauges. Where is the computer ground connection? I spoke with a friend of mine who works on a lot of Saturns. He said it is probably is the BCM. He said he has seen 5 or so Saturns do this from a bad BCM. He said this is a Saturn only repair because of the programming of the BCM, and it would cost about $750. He said I might be able to convince a Saturn dealership to program a new BCM and sell it to me and then I could install it. Can any of you give step by step directions for this? Does the module need to be protected from static? Do I need to wear my computer repair ground strap?

[fdryer]

Working with electronics doesn't make me an expert ( :whoa: ) BUT there are procedures that are outlined for precautions against any bare circuit board that's handled requiring static protection. With preassembled boards enclosed in metal containers for physical, electrical, and electrostatic protection, the BCM is already encased in a steel cocoon and if seen in its shipping box, the BCM would most likely be packed in its own electrostatic bag protected in electrostatic foam in a cardboard box. When taken out of the bag the tech would be wearing a wrist device that grounds the body with a coiled cord clipped to either a static placemat grounded to a static protected workbench. The unpacking would be taking place on the static placemat. There may be more measures to ensure static doesn't have a chance of blowing sensitive electronic components. All this may be moot because of relaxed standards and experience in everyday handling of well protected electronics like the BCM. When electronics are encased in a steel/plastic enclosure, static becomes much less a problem by simply handling them in the least amount of time and minimizing the time required to disconnect and connect the replacement, reducing the chances of static induced problems. As a hint, sweaty hands may be an advantage as moisture while handling the BCM and touching the car frame grounds the body from static generated from some car seats!? The only time a BCM would be removed from its static protective bag would be while sitting in the car just prior to connecting it to the electrical harness. In other words, there's a possibility that nothing is done for static protection, affording easier handling as long as simpler precautions are taken such as ensuring battery power removed, careful handling of expensive parts that are still static sensitive by not working around static generating areas and proper grounding of the BCM when connected to the car. For all we know, no such extra handling is done behind closed doors at the dealers as we expect a working car for the work done otherwise somebody loses money and once in a while the dealer may take a hit for poor handling of expensive electronics or they fail out of the box!? I have seen this at work with electronics failures in new replacement parts. The world wide distribution of GM products requires great thought in engineering electronics that will be used and abused in the most harshest conditions possible so simply looking at a BCM is no small feat to have sitting on some shelf waiting to be programmed and installed in someone's car.

The main reason most dealers, if not all of them, decline the request of any car owner to install his/her own ($$$) customized electronics like the BCM or ECM would be to minimize the very real possibility of mishandling electronics via static or even fumbling one by dropping it resulting in damage. By doing everything in-house Saturn can minimize and control any losses as Saturn assumes the risks that most uninformed car owners aren't appreciative of. And another reason for the high costs involved. Anyone can ask or demand a programmed BCM not be installed and installed by anyone not affiliated with Saturn (you the car owner) but there may be resistance to this unless some sort of agreement is arrived at that the unauthorized installer assumes all risks and absolves Saturn of any damage resulting in non-Saturn personnel installing expensive replacement electronics. If this seems more than what anyone wanted to know, its because of the legal/liability consequences of a poor/faulty/incorrect/incompetent installation that Saturn would be right to assume if anyone were to install their own ECM/BCM/ABS/SDM (airbag) electronics and expect a warranty. Put another way, Saturn ain't gonna' guarantee a BCM as the warranty stops as soon as it leaves the premises in the hands of the car owner expecting a simple replacement. Not to take sides but if I were Saturn I wouldn't guarantee any electronics if it deviates from established procedures requiring Saturn personnel to install these parts in order to have a valid warranty otherwise who's to judge whether or not you or I installed and blew up a BCM from simply connecting the harness incorrectly? A very simple error that can be done by anyone but in a Saturn stall Saturn takes the hit for damage and not the car owner. Taking a BCM home for installation automatically entails risks away from Saturn premises that Saturn will not assume. Take this into consideration when asking to have a preprogrammed BCM available for you to install yourself. It can be the easiest install as far as I'm concerned but not according to the liability concerns that aren't addressed when you want to save a few dollars. Personally, I don't see any problem installing electronics for myself and am aware of the concerns Saturn has but there's the problem - will a local dealer allow a car owner to install an expensive part and still guarantee it? Some food for thought. :sleep:

BTW, Saturn will/has to determine a faulty BCM before replacing one. Wouldn't it be embarrassing if Saturn made a mistake when it was the ECM instead? When you replace parts you assume all risks and mistakes including the troubleshooting that you determine is the BCM. Its the same risks but now its in your hands. As far as replacement procedures its just plug and play. Yes, that simple. But look before you leap - there are multiple pins in the connector and more than one connector. Mistakes can be costly if you're not prepared.

[Rivernut]

I called the local Saturn dealer. They will not sell it to me without also installing it. Total price estimate was about $500. They had 3 in stock, which says something. I am still driving the Vue without any outward symptoms other than the cycling warning lights and jumpy gauges. I have probably put on 1500 miles or so since the problem began. Looking back on this, I believe the first sign of trouble was when the odometer light went dim / out. I thought it had burned out again and was prepared to replace it with the same little Radio Shack bulb that I had bought before. A few days later the dash board became possessed. Is Saturn likely to hit me for the $90 or whatever fee for a code read even though I tell them it probably needs a BCM?

[Ritz]

[oops...double post]

[Ritz]

Yup. 'fraid so. That's the first time I've heard of a dealer "refusing" to sell a part to a customer because they didn't want someone else to install it. I've never done a BCM on a VUE so I don't know how involved it is, but that seems a bit fishy.

Try this and tell me if it makes sense; for Saturn to give anyone any warranty for a big ticket item like the BCM, controlling the in-house removal and installation will minimize the remote possibility of static ruining a perfectly good piece of electronics that the average person is totally unaware of. So if Saturn hands over a BCM that, by design is static sensitive and comes in its own static protective bag for use and installation by trained people aware of electrostatic problems, to a customer then is Saturn is supposed to trust that person to exercise static protection for the BCM installation to give a valid warranty? I don't think so.............and there's the dilemma not too many people seem to understand. On the one hand this is a plug n' play BCM but its also expensive electronics that is prone to static and for Saturn to allow a warranty for it, this would require them to handle the installation to remove the chances of incorrect or electrical maladies not under their control unless a written release of all liability is given leaving the car owner sole responsibility for any damage incurred while handling it in an uncontrolled manner. Never mind that they (Saturn) can toss our BCM's at will, around the shop but its inside Saturn premises so when installation is complete and something goes wrong Saturn eats the mistake. I think Saturn or any other car dealer would be nuts to hand over a BCM to a customer and warrant it? Most likely not so they are within standard business practices to ensure the outcome to afford a warranty.

Now with all that's said, would anyone want to take the risk of a non warranted newly programmed BCM in their hands and install it? What if it fails? Who's at fault? Saturn will simply state (in this presumed scenario) that the individual is not a Saturn authorized employee and a written release was given to assume all risks so any damage incurred is the sole responsibility of the individual.

That's all well and good, but at the end of the day the guy is a customer and he wants to buy a replacement part. I don't know the legality of it, but I would be surprised if Saturn could refuse to sell the part to someone with a Saturn vehicle who would like to have it repaired elsewhere (whether they do it themself or have another trained mechanic do it).

Cheers,

[fdryer]

I believe its all about liability and minimizing it not so much as outright refusing to sell as much as anyone wants the warranty protection for it. A BCM is not an inexpensive item so in order to afford a warranty Saturn would be right to refuse selling a programmed BCM to anyone unless that person is (in GM's determination) well versed in handling electrostatic sensitive components - the electronic specialists already knowledgeable ((I wouldn't post this unless I'm familiar with this issue). The one chance out of a hundred installations that goes wrong with a warranty that some customer incorrectly put in is one mistake GM isn't going to take. Why would they allow it? It doesn't make business sense and they are going to minimize the risk factor by not allowing unauthorized installation that has any chance of going wrong.

By that logic, Saturn also shouldn't sell a customer a replacement oil drain plug. One out of 100 people might not tighten it properly and have it wobble out and blow their engine. That line of reasoning doesn't fly with me. I think the customer should complain. It's not up to the guy at the parts counter to determine who can and who can not purchase replacement parts. If that guy wants to dispense "I wouldn't do that" advice, that's one thing, but outright refusing to sell the part is just plain wrong and I'd be surprised if it is legal to do so.

Bought my Vue 2003 after it was just over one year and half old, online from dealer (not saturn). For export.

When I received in home country outside of USA, service light and wrench was on permanently unless car was shut off. Drove car for 3 years with said light on but had absolutely no problem with running of car. however, could not get anyone in my country to determine why light was on.

Recently, I had chronic problems such as power locks relocking when opening with remote- car not starting, stiff power steering, all gauges flat, remote not working at all, many other dash lights coming off and on when in operation from time to time (ABS light, brake lights, air bag light, blinking daylight running lights), vehicle became unreliable with respect to starting.

Finally diagnosed for myself after reading about somewhat similar problems and putting it together in my head based on this forum. It was a BCM issue. Went to mechanic in my country and told him I suspect it is BCM can he do further investigations (has access to Saturn/GM through online subscription), he finally was able to look up BCM details (Saturn/GM) for 2003 Vue and he discovered there was a flag on the Saturn/GM system that indicated apparently all 2003 Vues (or a batch) BCMs were wrongly calibrated from factory. But there was no recall. He was also able to get from Saturn/GM online info (subscription) that there were new calibration numbers for BCM. Physical inspection indicated original BCM had incorrect factory installed calibration as website indicated and thus needed new calibration numbers provided by GM web site.

He advised me to purchase new BCM out of USA Saturn Dealer (USD$300) which I did. He calibrated here in my home country. Even though my car never gave any problems over the previous three years with service light with wrench on, finally 2 months ago the symptoms mentioned above cropped up and every thing went downhill in terms of reliability.

After calibrating new BCM with correct codes, my Vue runs like it has never run in the previous 3 years of ownership, never. It has smooth ride never enjoyed previously, gear change is seamless with acceleration, more power which vehicle never had and now drives like a dream. All error lights finally for first time off on dashboard including service light and wrench.

Maybe your issue with service light and wrench is a precursor to the problems I eventually had.

[Rivernut]

I had Saturn of Springfield, MA replace the BCM. Total cost was $412. No more service wrench light or dancing gauges. They gave me two new keyless entry remotes. They are a newer style. Maybe I can use the old one on one of my other GM's. In typical fashion for the lemon Vue, the ABS light stayed on because of yet another defective wheel bearing singing away. I still haven't finished troubleshooting the driver seat heater or figured out which fuel line tool to use to replace the filter @ 124,000 miles. Too many things break too quickly on these Vues.

[pdough]

Wheel bearing issues will NOT cause a check engine light. Look somewhere else...

[pdough]

Having to replace a fuel filter at 124,000 isn't too bad in my opinion. A few years ago you might be replacing a motor...

[Rivernut]

I said the ABS light, not check engine light. It is common to have a misreading wheel sensor as the bearing it is with fails. This triggers the ABS light. I can hear the bearing noise at the passenger rear wheel.
