That's a pesky one. From either sjmautomatic or 20v.org I gathered that the
test current runs from the auto check system through the left brake pad,
then the right brake pad to ground somewhere. You can probably find a more
accurate definition of "somewhere" in the Bentley Manual... :-) If you
don't care about the test system and basically just want it to stop beeping
at you, then I suggest grounding the appropriate wire in the harness for
the left brake pad. But, obviously, the right way of repairing the system
would include tracing the wires around and fixing either the bad ground,
the broken wire, or both.
