Question about 2001 Lincoln LS
Brake lighting is controlled by the REM, (Rear Electronic Module). The brake pedal position (BPP) switch is hardwired to the REM. When the brake pedal is depressed, the BPP switch will input information to the REM. Then, the REM will process the information and output to the left, right, and high mounted stoplamps. Only the left and right stoplamps will provide lamp outage indication.
The vehicle's electronic functions are divided into zones. The FEM controls the front portion of the vehicle and the REM controls the rear portion of the vehicle. These systems rely heavily on the SCP communication network in order to transmit and receive signals. As a technician it is very important to understand:
Measure the voltage between LR stop lamp C414 pin 1, circuit 29S-LF23 (OG), harness side and ground.
GO to R4 .
REPAIR the circuit. TEST the system for normal operation. ------------------ Measure the voltage between LR combination lamp C414 pin 3, circuit 31S-LG14 (BK/OG), harness side and ground.
