B1482

Diagnostic Chart:

Schematic:

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 DTC SETS
The BCM stores DTC B1482 in memory.

CONDITIONS FOR CLEARING THE MIL/DTC
^ A current DTC B1482 will clear if the short to ground is no longer detected by the BCM
^ A history DTC B1482 will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present nor any other malfunction in the BCM is detected.

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 inadv. power input circuit.
- The BCM is intermittently shorted to ground.

TEST DESCRIPTION
The number(s) below refer to the step number(s) on the diagnostic table.
4. Checks for a short to ground in the lnadv. Power Input circuit.
