TPMS learning mode.

[rkert99]

I bought a set of aftermarket wheels for my Astra so I need to reset the TPMS. I have one of the tools to do that but i can't get the car to go into learning mode. I followed what I thought was the correct procedure. Turn the ignition to the on position but don't start the car and then press the lock and unlock buttons on the key fob simultaneously. But nothing is happening. Is there a different procedure for the Astra or for a manual car?

Not sure but astra does not use gm tpms system. Think that procedure is for gm cars. Thinking maybe you need a tool .

There is no tool required. As long as you bought the correct tpms sensors the car will self learn the sensors while driving above 15mph for a couple miles. The astra uses a passive sensor system where the car monitors the pressure but not at a specific tire, it won't tell you which tire is low just that there is low pressure.

Did anyone manage to figure out how to reset the TPMS in case the Saturn Astra does not auto reset? I am just tired to look at the yellow sensor light on the dash. Thanks!

Based on this....It auto resets

It auto resets, chances are that you have a dead TPMS sensor. I've already replaced all of mine when the batteries failed 3 years ago

Thanks for the advice! But I never had any issue with the sensor, before changing two tires in the front and moving the best remaining two in the back. It this is indeed the case, I guess I will have to wait until I change the other two tires to replace all sensors.

Is there info in the owner's manual on life expectancy of tpms batteries. General info says no more than ten years but recommendations are to replace sensors when replacing tires. Calculation of tire life in years can determine when to replace sensors to maximize their use while avoiding dead batteries and adding costs to sensor replacement from needlessly dismounting a tire for sensor replacement.

Based on this...it seems a possibility could be that one or both of the sensors were damaged or removed and replaced with new valve stems. Also, moving a sensor with a weak battery farther from the receiver could cause this sort of issue. A tire shop might be able to use their TPMS tool to communicate with each sensor and read battery level.
