Sorry for bumping this thread but im having the same issue, service immobilizer on display.
I noticed my wiring under the car was ripped apart, more than likely my dog.....We've noticed some small rats around the yard but nothing too big. Anyways, I was able to wire some of these guys back up, nothing fancy but enough to make contact. I still have to clean it up, solder it and tape it up.
This is in the back, 3/4 of the way to the rear of the car, down the middle.
Does anyone know what this is for?
Car is still not turning on though, keeps saying SERVICE IMMOBILIZER.
Any help would be appreciated.
