Circuit Description
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 measures the resistance to the one stored in the IPCs memory.
Conditions for Setting the DTC
The IPC determines that one of the 15 valid key pellets was detected, but the DTC does not match the resistance of the one stored in the IPCs memory.
Action Taken When the DTC Sets
The IPC displays the STARTING DISABLED, DUE TO THEFT SYSTEM, REMOVE IGNITION KEY message on the driver message center and prevents the vehicle from starting. The IPC then starts the 3 minute delay sequence with messages.
