Brake Lamp: Pinpoint Tests
Test G: One Or More Stoplamps Are Inoperative
PINPOINT TEST G: ONE OR MORE STOPLAMPS ARE INOPERATIVE
Normal Operation
The smart junction box (SJB) provides voltage to the stoplamp switch through circuit SBP19 (BU/RD). When the brake pedal is applied, voltage is
routed to the high mounted stoplamp and the multifunction switch through circuit CCB08 (VT/WH). The multifunction switch then routes the voltage
to the LH and RH rear lamps through circuits CLS35 (VT) and CLS36 (YE), respectively. Ground is provided through circuit GD161 (BK/YE) for the
high mounted stoplamp and through circuit GD121 (BK/YE) for the rear lamps.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
Stoplamp switch
-
High mounted stoplamp
-
Multifunction switch
