Circuit/System Testing
- Ignition OFF. Disconnect the harness connectors at the BCM.
- Test for less than 3.0 ohms between the ground circuits terminals listed below and ground.
- Terminal 12 X1
- Terminal E2 X4
- If greater than the specified value, test the ground circuit for an open/high resistance.
- Ignition ON, verify a test lamp illuminates between the B+ circuit terminals listed below and ground.
- Terminal D6 X3
- Terminal D1 X3
- If test lamp did not illuminate, test the B+ circuits for a short to ground or an open/high resistance.
- If all the circuits test normal, replace the BCM.
