Scan Tool Testing and Procedures




BODY CONTROL MODULE (BCM) INSPECTION

1. Remove the glove compartment.

2. Remove the BCM with the connector connected.

3. Measure the voltage at each terminal and inspect that the continuity between the terminals and ground is as indicated in the Terminal Voltage Tables (Reference).

- If the voltage or continuity is not as specified in the Terminal Voltage Table (Reference), inspect the parts under "Inspection item (s)".

- If the system does not work properly even though the parts or related wiring harnesses do not have any malfunction, replace the BCM.
