Disabling the Autocheck headlight monitor
After adding relays to the stock headlight system, or upgrading to
Eurolights and relays, the Autocheck system for the low beams will stay on.
The easiest fix is to disable it.
On a 200 go to the aux relay block in the driver side footwell. The relay in
question is the second from the right in the middle row.
Prepare 2 pieces of wire 2" long each, with the standard male spade
on both ends.
Take the relay out and jump 2 pairs of female terminals on the socket.
ACHTUNG! DO NOT screw up this step!
Jump 56L and 56L1.
Jump 56R and 56R1.
> Can you disable just the headlight portion?
Correct. This relay (#5 on a 200) monitors just the headlights portion of
91 200 TQA
