Engine Electrical Diagnosis

CIRCUIT DESCRIPTION
The Body Control Module (BCM) provides an interface to the electrical loads which are controlled by the inadvertent power circuit.

CONDITIONS FOR RUNNING THE DTC
If the voltage level at the BCM drops to 0.

CONDITIONS FOR SETTING THE DTC
The BCM detects a low when a high is expected. The condition above must be present for more then 0.1 seconds

ACTION TAKEN WHEN THE DTC SETS
The BCM stores DTC B1482 in memory.

CONDITIONS FOR CLEARING THE MIL/DTC
^ A current DTC B1482 clears when the BCM no longer detects a short to ground.
^ A history DTC B1482 clears after 100 consecutive ignition cycles.

DIAGNOSTIC AIDS
^ If the DTC B1482 is a history DTC, the fault may be intermittent. Refer to Testing for Intermittent and Poor Connections in Diagrams.
^ The following conditions may cause an intermittent malfunction to occur:
- An intermittent short to ground in the inadvertent power input circuit.
- The BCM is intermittently shorted to ground.

TEST DESCRIPTION

Steps 1-7:

The number(s) below refer to the step number(s) on the diagnostic table.
4. This step tests for a short to ground in the inadvertent power input circuit.
