Test C: The Headlamps On Warning Chime Is Inoperative

PINPOINT TEST C: THE HEADLAMPS ON WARNING CHIME IS INOPERATIVE

Normal Operation
The smart junction box (SJB) receives the headlamp switch status from the headlamp switch and the LH front door ajar status from the LH front door ajar switch through hardwired circuitry. The headlamps on warning chime sounds when the LH front door is opened with the ignition switch in the OFF position, and the headlamp switch is in the PARK or HEADLAMP ON position. The SJB communicates the headlamp on chime request to the instrument cluster (IC) when the headlamps or parking lamps are on and the driver door is opened. The autolamps feature must not be selected for the headlamps on warning chime to operate.

This pinpoint test is intended to diagnose the following:
- Door ajar indication
- SJB
- Instrument cluster (IC)
