Test H: One Or More Stoplamps Are Inoperative
PINPOINT TEST H: ONE OR MORE STOPLAMPS ARE INOPERATIVE
Normal Operation
When the brake pedal is applied, voltage is routed from the central junction box (CJB) through circuit 511 (LG) to the high mounted stoplamp and the
multifunction switch. The multifunction switch then routes the voltage to the rear lamps through circuit 9 (LG/OG) (LH rear lamp) and circuit 5
(OG/LB) (RH rear lamp). The stoplamps share a common ground through circuit 57 (BK).
This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
-
Bulb holder (non-cutaway vehicles)
-
Rear lamp assembly (cutaway vehicles)
-
High mounted stoplamp
-
Multifunction switch
