Test G: The Puddle Lamp(s) Are Inoperative

PINPOINT TEST G: THE PUDDLE LAMP(S) ARE INOPERATIVE

Normal Operation
The smart junction box (SJB) provides voltage to the puddle lamps through circuit CLN25 (VT). The puddle lamps have separate ground circuits. The LH exterior mirror is grounded through circuit GD133 (BK), and the RH exterior mirror is grounded through circuit GD148 (BK/YE).

DTC B2A39 (Puddle Lamp Output Circuit Open) - is an on-demand DTC that sets when the SJB detects an open on the puddle lamp output circuit.

DTC B2A3A (Puddle Lamp Output Circuit Short To Ground) - is a continuous and on-demand DTC that sets when the SJB detects a short to ground on the puddle lamp output circuit. This DTC also sets as a result when the SJB fuse 10 (15A) has failed or is removed.

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