Circuit/System Testing
- Ignition OFF, disconnect the harness connectors at the BCM.
- With the ignition OFF and the scan tool disconnected, open and close the drivers door, and wait 30 seconds. Test for less than 5 ohms between the following ground circuit terminals and ground:
- Terminal 1 X3
- Terminal 5 X3
- Terminal 9 X4
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Ignition ON, verify that a test lamp illuminates between the following B+ circuit terminals and ground:
- Terminal 3 X3
- Terminal 10 X4
- 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.
