WARNING: This page is about a different car, the 2009 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
- AJ1 CHECK FOR DRIVER DOOR AJAR INPUT TO THE SJB
- Check the operation of the interior lamps while opening and closing the driver door.
- Do the interior lamps operate correctly?
- YES : Go to AJ2.
- NO : REFER to INTERIOR LIGHTING .
- AJ2 CHECK INSTRUMENT CLUSTER (IC) CHIME FUNCTION
- Key in OFF position.

- Open the driver door.
- Does the headlamps on warning chime sound?
- AJ3 CHECK THE INPUT TO THE INSTRUMENT CLUSTER (IC) FOR DTC B1353
- Disconnect: Instrument Cluster (IC) C220
- Insert the ignition key into the ignition lock cylinder.
- Measure the voltage between the instrument cluster (IC) C220-13, circuit 1414 (LG/VT), harness side and ground.
- Is the voltage greater than 10 volts?
- AJ4 CHECK CIRCUIT 1414 (LG/VT) FOR AN OPEN
- Disconnect: Ignition Switch C250
- Measure the resistance between the instrument cluster (IC) C220-13, circuit 1414 (LG/VT), harness side and the ignition switch C250-5, circuit 1414 (LG/VT), harness side.
- Is the resistance less than 5 ohms?

- YES : INSTALL a new ignition switch. REFER to STEERING COLUMN SWITCHES . CLEAR the DTCs. REPEAT the self-test.
- NO : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
- AJ5 CHECK FOR CORRECT INSTRUMENT CLUSTER (IC) OPERATION
- Disconnect the instrument cluster (IC) connector.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect the instrument cluster (IC) connector and make sure it seats correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- YES : INSTALL a new instrument cluster (IC). REFER to Instrument Cluster (IC) . TEST the system for normal operation.
- NO : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
