PINPOINT TEST A: THE CHIME SOUNDS WHEN THE DRIVER DOOR IS AJAR (NO KEY IN IGNITION AND HEADLAMPS OFF)

Normal Operation
When the key is inserted into the ignition lock cylinder, the key-in-ignition switch (part of the ignition switch) closes, providing a voltage signal to the smart junction box (SJB) through circuit CDC30 (BU/GY). The key-in-ignition and door ajar status is communicated to the instrument cluster from the SJB over the medium speed communication area network (MS-CAN). If the instrument cluster detects that the ignition switch is in the OFF or ACC position and the SJB communicates to the instrument cluster that the driver door is ajar and the key is in the ignition, the key-in-ignition warning chime sounds. The SJB also communicates to the instrument cluster that the headlamps or parking lamps are on and the driver door is opened for the headlamps on warning chime. The headlamps on warning chime sounds when the driver door is opened with the ignition switch in the OFF position, the key is not in the ignition lock cylinder, and the headlamp switch is in the PARK or HEADLAMP ON position.

DTC B1352 - is an on-demand DTC that sets if the SJB detects an open or short to ground on the key-in-ignition switch input, circuit CDC30 (BU/GY) or if the SJB detects ignition START, RUN/START or RUN/ACC inputs without the key-in-ignition input.

Possible Causes
- Circuit CDC30 (BU/GY) short to voltage
- Ignition switch
- SJB
