Checking the wiring for the lamp housing

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

Check the cable between the passenger compartment fuse and terminal #3 of the lamp housing for each headlamp.

For the left low beam, check lamp housing 10/1.

For the right low beam, check 10/2.

Check the ground supply between lamp housing #1 and the ground terminal.

Also check the connectors: 54/3L, 54/4.

Remedy as necessary.

If no fault was found, replace the lamp housing.
