Checking components and wiring
Check the connectors for the rear electronic module (REM) and tail lamps. Check for contact resistance and oxidation. Check for loose connections. Check for damage carefully.
Check the power supply cable between rear electronic module (REM) terminal #4D (#B04) and connector terminal #7 on the left tail lamp. Check for an open-circuit. Check for a short-circuit to supply voltage.
Check the power supply cable between left tail lamp connector terminal #7 and right tail lamp terminal #7. Check for an open-circuit. Check for a short-circuit to supply voltage.
Also check the ground lead between tail lamp connector terminal #8 and the ground terminal. Check for an open-circuit.
Try a new brake light if no faults were found.
