CIRCUIT DESCRIPTION
When an ignition key is inserted into the ignition switch, the terminals located in the steering column lock cylinder contact the key pellet resistor on 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 DTC will set under the following conditions:
^ B2710 indicates that an open or zero resistance value was measured from the key pellet prior to obtaining a valid resistance measurement.
^ B2711 indicates that an open or zero resistance value was measured from the key pellet following a valid resistance measurement.

ACTION TAKEN WHEN THE DTC SETS
^ When DTC B2710 is set current the IPC displays the STARTING DISABLED, REMOVE IGNITION KEY message on the driver message center and prevents the vehicle from starting.
^ When DTC B2711 is set current the IPC displays the THEFT SYSTEM PROBLEM, CAR MAY NOT RESTART message on the driver message center and allows the vehicle to continue to run.
