Test A: The Courtesy Lamps Are Inoperative

PINPOINT TEST A: THE COURTESY LAMPS ARE INOPERATIVE

Normal Operation
Voltage is supplied to the courtesy lamps by the smart junction box (SJB) fuse 9 (15A). When the SJB receives a request for the courtesy lamps the SJB energizes the solid-state relay supplying voltage to the courtesy lamps on circuit VLN33 (GY/VT). Ground for the courtesy lamps is supplied through circuit GD133 (BK).

- DTC B2A35 (Interior Lighting Output Circuit Open) - is an on-demand DTC that sets when the SJB detects an open from the interior lighting circuit.
- DTC B2A36 (Interior Lighting Output Circuit Short to Ground) - is a continuous and on-demand DTC that sets when the SJB detects a short to ground from the interior lighting circuit.

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Interior lamp
- SJB
