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
check for an open-circuit or short-circuit to ground.
Check the cable between the left or right lower lamp housing terminal #4 and the ground terminal for an open-circuit.
Check that the bulbs are intact.
Remedy as necessary.
