Fusion AWD L4-2.3L (2008)
Brake Lamp: Pinpoint Tests
Test I: All The Stoplamps Are Inoperative
PINPOINT TEST I: ALL THE STOPLAMPS ARE INOPERATIVE
Normal Operation
For all vehicles, the stoplamp switch is supplied voltage through circuit SBP04 (GN/RD) from the smart junction box (SJB). When the brake pedal is
applied, the stoplamp switch routes voltage to the SJB through circuit CCB08 (VT/WH).
For Fusion, the SJB provides voltage to the rear stoplamps.
For Milan and MKZ, the voltage is routed through the SJB to all the stoplamps through circuit CLS17 (YE/GY).
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
Stoplamp switch
-
SJB
