Test H: The Autolamps Are On Continuously

PINPOINT TEST H: THE AUTOLAMPS ARE ON CONTINUOUSLY

Normal Operation
The smart junction box (SJB) sends reference signals to the headlamp switch through circuits CLF18 (BU/WH), CLF19 (VT/GN), CLF23 (WH/VT) and CLS34 (GY). The SJB also sends a reference signal to the light sensor through circuit VLF14 (BU/BN). Ground for the light sensor is provided through circuit GD116 (BK/VT).

When the headlamp switch is placed in the AUTOLAMPS ON position, the voltage signal is routed to ground through circuit GD116 (BK/VT). The light sensor determines the amount of light based on the input received from the ambient sky conditions. When the ambient level has reached a point (determined by the internal programming of the SJB), the SJB provides voltage to the exterior lamps.












This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Light sensor
- Headlamp switch
- SJB
