This circuit supplies the Passlock(R) data to the Body Function Controller (BFC) from the Passlock(R) Sensor, circuit 1836.

CONDITIONS FOR SETTING THE DTC
All of the following conditions must be met:
^ The Passlock� option is enabled.
^ Ignition 0 is active,
^ The Passlock� code does not equal the learned key code during Engine start or for 1 second at any time during an ignition cycle.

ACTION TAKEN WHEN THE DTC SETS
^ The Body Function Controller (BFC) enters tamper mode.
^ Stores DTC B2960 in the Body Function Controller (BFC) memory.
^ DTC B2960 will be set at key on and after an attempted start or while driving the SECURITY indicator illuminates and the vehicle will start on next key on.

CONDITIONS FOR CLEARING THE DTC
^ The Body Function Controller (BFC) goes to sleep and reinitializes with the fault cleared.
^ All Body Function Controller (BFC) history codes will be cleared after 100 ignition cycles (from OFF to RUN) with no current codes active during the 100 ignition cycles.
^ Using a scan tool.

DIAGNOSTIC AIDS
^ When the diagnostics direct you to take electrical measurements at the Wiring Harness Junction Blocks , refer to Power Distribution, in Electrical Diagnosis, for terminal assignments of the Wiring Harness Junction Blocks
^ If the DTC is a history DTC, the problem may be intermittent. Try performing the tests shown while wiggling wiring and connectors, this can often cause the malfunction to appear.
