Circuit/System Testing
- Ignition OFF, disconnect the harness connectors of the appropriate control module.
- Ignition OFF and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 5 Ω between the ground circuit terminals listed below and ground:
- Terminal 10, P16 Instrument cluster
- Terminal A2, K85 Passenger presence detection module
- Terminal 19 X1, K86 Inflatable restraint sensing and diagnostic module
- Terminal 11 X1, T11 Multimedia player interface module
- Terminal 38 X1, A11 Radio
- Terminal 7 X1, K41 Parking assist control module
- 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 20, P16 Instrument cluster
- Terminal A1, K85 Passenger presence detection module
- Terminal 9 X1, K36 Inflatable restraint sensing and diagnostic module
- Terminal 1 X1, T11 Multimedia player interface module
- Terminal 44 X1, A11 Radio
- Terminal 1 X1, K41 Parking assist control module
- If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
- If the circuits test normal, replace the appropriate control module.
