Test A: The Key-In-Ignition Warning Chime Is Inoperative

PINPOINT TEST A: THE KEY-IN-IGNITION WARNING CHIME IS INOPERATIVE

A1-A4:

A4-A5:

Normal Operation
When the key is inserted into the ignition cylinder, the key-in-ignition warning switch (part of the ignition switch) closes circuit CDC30 (BU/GY) to the instrument cluster, providing a voltage signal. The voltage input signals the instrument cluster that the key is inserted. Door ajar status is communicated to the instrument cluster from the smart junction box (SJB) through the controller area network (CAN). If the instrument cluster detects that the ignition lock cylinder is in the OFF or ACC position, the key is inserted in the ignition cylinder, and the SJB communicates to the instrument cluster that the driver door is ajar, the key-in-ignition warning chime sounds.

DTC B1352 - is a continuous DTC that sets if the instrument cluster does not sense voltage applied on circuit CDC30 (BU/GY) with voltage applied to circuit CBP23 (BN/YE) or CBP20 (YE/VT).

Possible Causes
- Circuit CDC30 (BU/GY) open or short to ground
- Key-in-ignition warning switch (part of the ignition switch)
- Instrument cluster
