Circuit/System Testing
- Engine running, accessories OFF, measure and record the battery voltage at the battery terminals. The voltage should be between 12.6 and 15.0 volts.
- If not within the specified range, refer to Charging System Test .
- Ignition OFF, disconnect the harness connectors at the appropriate module.
- Ignition OFF and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 5 ohms between the following ground circuit terminals and ground:
- Terminal 15 (IPC)
- Terminal 16 (IPC)
- Terminal 31 (SDM)
- Terminal 8 X1 (Radio)
- Terminal 61 X1 (BCM)
- Terminal 64 X1 (BCM)
- Terminal E12 X4 (BCM)
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Verify that a test lamp illuminates between the following B+ circuit terminals and ground:
- Terminal 1 (SDM)
- Terminal 13 (IPC)
- Terminal 1 X1 (Radio)
- Terminal D12 X3 (BCM)
- 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 appropriate module.
