PINPOINT TEST B: THE HEADLAMPS ON WARNING CHIME IS INOPERATIVE

B1-B3:

Normal Operation
When the key is inserted into the ignition lock cylinder, the key-in-ignition switch (part of the ignition switch) closes and routes a voltage signal to the instrument cluster through circuit 1414 (LG/VT). When the ignition key is not inserted into the ignition lock cylinder, the driver door is ajar and the headlamps are on, the smart junction box (SJB) sends a message to the instrument cluster over the medium speed controller area network (MS-CAN). The instrument cluster interprets this signal and sounds the headlamps on warning chime.

Possible Causes
- SJB
