Pinpoint Test A: The Key-In-Ignition Chime Is Inoperative: Testing

A1 CHECK FOR DRIVER DOOR AJAR INPUT TO THE SMART JUNCTION BOX (SJB)
- Check the operation of the interior lamps while opening and closing the driver door.
- Do the interior lamps operate correctly?
- Yes : GO to A2.
- No : REFER to INTERIOR LIGHTING to continue diagnosis of the interior lamps.
A2 CHECK THE INPUT TO THE INSTRUMENT CLUSTER FOR DTC B1352
- Key in OFF position.
- Disconnect: Instrument Cluster C220.
- Insert the ignition key into the ignition lock cylinder.
- Measure the voltage between the instrument cluster C220-7, circuit 3410 (YE), harness side and ground.

- Is the voltage greater than 10 volts?
- Yes : GO to A4.
- No : GO to A3.
A3 CHECK CIRCUIT 3410 (YE) FOR AN OPEN
- Disconnect: Ignition Switch C250.
- Measure the resistance between the instrument cluster C220-7, circuit 3410 (YE), harness side and the clockspring C250-5, circuit 3410 (YE), harness side.

- Is the resistance less than 5 ohms?
- Yes : INSTALL a new ignition lock cylinder. REFER to HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS . CLEAR the DTCs. REPEAT the self-test.
- No : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
A4 CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION
- Disconnect the instrument cluster connector.
- Check for:
  - corrosion
  - pushed-out pins
- Connect the instrument cluster 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. REFER to INSTRUMENT CLUSTER . 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.
