2.  Set the bonnet release lever out of the way. (L.H.D.) (See BONNET LATCH AND RELEASE LEVER REMOVAL/INSTALLATION.)

3.  Remove the lower panel. (L.H.D.) (See LOWER PANEL REMOVAL/INSTALLATION.)

4.  Set the starter cut relay out of the way. (with advanced keyless entry and push button start system) (MTX (L.H.D.)) (See STARTER CUT RELAY REMOVAL/INSTALLATION [MTX].)

5.  Remove the dashboard under cover. (R.H.D.) (See DASHBOARD UNDER COVER REMOVAL/INSTALLATION.)

6.  Remove the BCM with the connector connected. (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION [L.H.D.].) (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION [R.H.D.].)

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

•  If the voltage or continuity 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.
