When a key is inserted into the ignition switch, the terminals located in the steering column lock cylinder contact the resistor pellet in the ignition key. The IPC measures the resistance of the key pellet and then compares the resistance to the one stored in the IPCs memory.
A malfunction occurs in the communication between the IPC and PCM.
The IPC displays the THEFT SYSTEM PROBLEM, CAR MAY NOT RESTART message on the driver message center.
