B1369

CIRCUIT DESCRIPTION
Ignition 0 input to the body control module BCM is used to determine the power mode that the vehicle is in. If the BCM senses that the ignition 0 input is inactive when ignition 3 is active and the engine is running, DTC B1369 is set.

CONDITIONS FOR RUNNING THE DTC
^ The engine is running.
^ At least 20 seconds has elapsed since the engine was started.

CONDITIONS FOR SETTING THE DTC
The ignition 0 input is inactive after the engine has been running for 20 seconds.

ACTION TAKEN WHEN THE DTC SETS
^ Multiple indicators illuminate on the IPC panel.
^ 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.
^ A history DTC clears when the module ignition cycle counter reaches the reset threshold, without a repeat of the malfunction.

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.

TEST DESCRIPTION

Steps 1-5:

Steps 6-15:

The numbers listed below refer to the numbers on the diagnostic table.
4. This step determines if ignition 0 is shorted to ground.
5. This step determines if the body control module BCM is internally shorted.
6. This step determines if the instrument panel cluster IPC is internally shorted.
7. This step determines if voltage a voltage supply is present, from the battery to the fuse.
