BODY CONTROL MODULE (BCM) INSPECTION


id094000800300

1.  Remove the front scuff plate. (LH) (See FRONT SCUFF PLATE REMOVAL/INSTALLATION.)

2.  Remove the front side trim. (LH) (See FRONT SIDE TRIM REMOVAL/INSTALLATION.)

3.  Remove the BCM with the connector connected. (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION.)

4.  Measure the voltage at each terminal is as indicated in the Terminal Voltage Tables.

•  If the voltage is not as specified in the Terminal Voltage Table, 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.
