CIRCUIT DESCRIPTION
The body control module (BCM) receives accessory voltage from the ignition switch through the BCM fuse when the ignition switch is in the accessory or run position.

CONDITIONS FOR RUNNING THE DTC
^ The engine is running or the ignition 1 input is active for at least 30 seconds.
^ Voltage supplied to the BCM is in the normal operating range, approximately 9 - 16 volts.

CONDITIONS FOR CLEARING THE DTC
^ A current DTC B1382 clears when the code setting condition is no longer present.
^ A history DTC clears when the module ignition cycle counter reaches the reset threshold, without a repeat of the malfunction.

ACTION TAKEN WHEN THE DTC SETS
DTC B1382 is stored in the BCM memory.

CONDITIONS FOR SETTING THE DTC
The BCM does not detect the accessory input after 30 seconds.

DIAGNOSTIC AIDS

Device Power Moding:

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 1-12:

The numbers listed below refer to the numbers on the diagnostic table.
4. This step determines it the accessory input is shorted to ground.
