Checking the wiring and the relay

Check the signal cables to the low beam. Check for an open-circuit. Check for contact resistance and oxidation.

Check the relay (2/62).

HINT: The voltage over the relay must be 12 V on pins #1 and #3 when the low beam is switched on. 

Check the cable between terminal #3 and fuse 2, fusebox in the engine compartment (11B/2).

Check that fuse is intact.

Check the connector.

Check the cable between relay #1 (2/62) and shunt low beam #3 (20/27).

Check shunt (20/27).

HINT: The voltage must be 12 V at the shunt terminals, i.e. #3 and #2. 

Check the cable between shunt low beam #2 (20/27) and fuses low beam.

Check that the fuses are intact.

HINT: Passenger compartment fuse no. 1 for left low beam and no. 2 for right low beam. 

Remedy as necessary.
