B1382

Diagnostic Chart:

Schematic:

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 on position. If the BCM senses that the accessory input is inactive, DTC B1382 is set.

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

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

CONDITIONS FOR CLEARING THE DTC
^ DTC B1382 clears when the code setting condition is no longer present.
^ All 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 intermiffent. Perform the tests shown while wiggling the wiring and connectors. This can often cause the malfunction to appear.

TEST DESCRIPTION
The numbers listed below refer to the numbers on the diagnostic table.
4. This step determines if the accessory input is shorted to ground.
5. This step determines if the BCM is internally shorted.
6. This step determines if voltage is supplied from the battery to the BCM fuse.
