Pinpoint Test J: One Or More Stoplamps Are Inoperative
Refer to Wiring Diagram Set 90 (Escape/Mariner, Escape Hybrid/Mariner Hybrid), Turn Signal/Stop/Hazard Lamps for schematic and connector
information. See: Diagrams/Electrical Diagrams/Diagrams By Number
Normal Operation
When the brake pedal is applied, the stoplamp switch routes voltage to the Smart Junction Box (SJB) and the high mounted stoplamp through circuit
CCB08 (VT/WH). When the SJB detects the brake pedal is 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 LH and RH rear stoplamps is provided through circuit GD149 (BK/GY). Ground for the
high mounted stoplamp is provided through circuit GD183 (BK/WH).
NOTE: SJB fuse 6 (20A) supplies voltage for both combination rear stop/turn lamps and both front turn lamps.
