Circuit/System Testing
- Ignition OFF, disconnect the harness connectors at the BCM.
- Ignition OFF and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 5Ω between the ground circuit terminal B3 X1 and ground.
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Verify that a test lamp illuminates between the B+ circuit terminals listed below and ground.
- Terminal A7 X1
- Terminal B5 X1
- Terminal B8 X1
- If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
- If all circuits test normal, replace the BCM.
