BODY CONTROL MODULE (BCM) INSPECTION

id094000800300

1. Remove the dashboard under cover. (See DASHBOARD UNDER COVER REMOVAL/INSTALLATION.)

2. Remove the glove compartment. (See GLOVE COMPARTMENT REMOVAL/INSTALLATION.)

3. Measure the voltage at each terminal and inspect for 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.
