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, the key is not in the ignition lock cylinder, and the headlamp switch is in the PARKING or HEADLAMPS ON position. The SJB communicates the headlamp on chime request to the instrument cluster (IC) based on headlamp or parking lamp and driver door inputs. 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 concern
- SJB
- Instrument cluster (IC)
