Pinpoint Test 3
PINPOINT TEST 3: THE INTERIOR LAMPS DO NOT TURN ON WITH ONE DOOR OPEN
Normal Operation
NOTE: The smart junction box (SJB) is also known as the generic electronic module (GEM).
When any door is opened, the door ajar switch closes and signals the SJB/GEM. The SJB/GEM receives the door open signal and activates the interior
lamp relay
(integral to the SJB/GEM) and applies voltage to circuit (G/L).
This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
-
Door ajar switch
-
SJB/GEM
