B1369
CIRCUIT DESCRIPTIONIgnition 0 input to the body control module BCM and the instrument panel cluster IPC is used to determine the power mode that the vehicle is in. If the BCM senses that the ignition 0 input is inactive when it should be active, DTC B1369 is set.
CONDITIONS FOR RUNNING THE DTC
^ The ignition switch is on.
^ At least 20 seconds has elapsed since the ignition switch was cycled on.
CONDITIONS FOR SETTING THE DTC
The ignition 0 input is inactive after the ignition 1 input has been active for 20 seconds.
ACTION TAKEN WHEN THE DTC SETS
^ Multiple indicators illuminate on the IPC.
^ The vehicle will not start.
CONDITIONS FOR CLEARING THE DTC
^ A current DTC B1369 will clear when the malfunction is no longer present and the ignition switch is cycled.
^ BCM history codes will be cleared after 100 ignition cycles (from OFF to ON) with no current codes active during the 100 ignition cycles.
DIAGNOSTIC AIDS
If the DTC is a history DTC, the problem may be intermittent. Perform the tests shown while wiggling the wiring and connectors. This can often cause the malfunction to appear.
