Checking Components And Wiring
Check the voltage between the left and right-hand stop lamps and the output on the rear electronic module (REM). The voltage must be approximately 12 V when the stop lamp is activated.
Check the control signal cable. Check for an open-circuit. Check for a short-circuit to supply voltage.
Take readings between:
S60
- Rear electronic module (REM) terminal #B3 (#3) and stop lamp terminal #B4.
Check the cable between central electronic module (CEM) terminal #A15 (15) and rear electronic module (REM) terminal #A18 (18). Check for a short-circuit to supply voltage. Check for an open-circuit.
Remedy as necessary.
