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.
