Q: Immobilizer keeping car from starting.

asked by on

The immobilizer is on, so my car won't start.

Your car may need the service harness and relay installed into the wiring of your ignition switch; the tech bulletin is RJT 1678, to get the parts list and directions. This part is a fix to a few different problems peculiar to your car’s model and year. The parts would need to be installed after a diagnostic check, to see if no other problems with system are present. I would recommend hiring a certified mobile mechanic, such as one from YourMechanic, to inspect your car’s starting issue with this information in mind.
