Test J: One Or More Stoplamps Are Inoperative
PINPOINT TEST J: ONE OR MORE STOPLAMPS ARE INOPERATIVE
Normal Operation - Fusion
When the brake pedal is applied, the stoplamp switch routes voltage to the smart junction box (SJB). The voltage is then routed through the SJB to the
high mounted stoplamp through circuit CLS17 (YE/GY). When the SJB detects the brake pedal applied, the SJB provides voltage to the LH and RH
rear stoplamps through circuits CLS18 (GY/BN) and CLS19 (VT/OG), respectively. Ground for the rear stoplamps is provided through circuit GD171
(BK/GY).

When the SJB detects the brake pedal applied, voltage is routed through the SJB to the stoplamps through circuit CLS17 (YE/GY). Ground for the
stoplamps is provided through circuit GD171 (BK/GY).
The rear lamps contain electronics that modulate the voltage frequency to the LED bulbs.
This pinpoint test is intended to diagnose the following:
