Default security light?

found a seller with 03 v6 w/80k miles he says it has a security light issue and will randomly go into limp mode. i read many threads on limp mode and throttle issues with broken wire causes but am not familiar with a security light leading to limp mode. is this a different issue or the security system shutting down the vue? or do i need to see if it has codes first?

I'm not sure if the Passlock system would cause a limp mode...

However, If you wish to bypass the Passlock system, this is how I did it..

I believe you're describing two separate problems. Reduced power mode in Saturn speak (commonly known as limp home mode) and Passlock security. Reduced power mode involves the ECM, pedal, throttle and associated wiring. The cel/mil should be on with stored codes. Reduced power mode isn't a security issue and shouldn't turn on security. Passlock security has four modes; ON, Off, blinking slowly and flashing quickly. Passlock security doesn't turn on reduced power mode. When Passlock flashes quickly, injectors are disabled to prevent a car thief from trying to drive away.

80k miles is nice. almost as low as the vues with bad vti trans w/100k miles which seem common. i did see an 03 w/31k miles for crazy money. dealer wants $7k? he is adding $4k for the miles?
