Checking components and wiring

Check that fuse 11D/2 is intact.

Check that shunt 20/29 is not damaged. The resistance between the terminal pins is 0 ohm to 5 ohms depending on which pin the reading is taken at.

Check the cables between: 

fuse 11D/2 terminal #2 and rear electronic module terminal #4E

shunt 20/29 terminal #2 and relay 2/49 terminal #5

relay 2/49 terminal #3 and the left or right lower lamp housing terminal #3

for an open-circuit according to Open-circuit, permanent faults and a short-circuit to ground according to Short-circuit to ground, permanent faults .

Check the cable between the left or right lower lamp housing terminal #4 and the ground terminal for an open-circuit according to Open-circuit, permanent faults .

Check that the bulbs are intact.

Remedy as necessary.
