Connector End Views-Interior Lighting (Part 4)
Pinpoint Test 1
PINPOINT TEST 1: THE INTERIOR LAMP IS INOPERATIVE
Normal Operation
NOTE: The smart junction box (SJB) is also known as the generic electronic module (GEM).
Voltage is supplied to the SJB/GEM through circuit (GY/R). The SJB/GEM fuse 13 (15A) supplies voltage to the interior lamp relay (integral to the
SJB/GEM). When any door is opened, the door ajar switch closes, signalling the SJB/GEM. The SJB/GEM monitors the door ajar circuits, and the
instrument panel dimmer switch input. Based on these inputs, the SJB/GEM will supply voltage to the interior lamp on circuit (G/L).
