Test C: The Courtesy Lamps Stay On Continuously

PINPOINT TEST C: THE COURTESY LAMPS STAY ON CONTINUOUSLY

Normal Operation
When any door, the liftgate or the liftgate glass is opened, the ajar switch opens the circuit to the smart junction box (SJB). The SJB monitors the ajar circuits, and based on the ajar status, the SJB supplies voltage to the courtesy lamps on circuit CLN03 (YE/GY).

When the instrument panel dimmer switch is rotated to the dome detent, ground is supplied on circuit CLN28 (GN/BU) to the SJB. The SJB monitors the dome input circuit. Based on the input, the SJB supplies voltage to the courtesy lamps on circuit CLN03 (YE/GT).







This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Ajar switch
- Instrument panel dimmer switch
- SJB
