95 540 M-Motorsport EDC Ground issues

1127 2
EDC not functioning at will. Turns on and off seemingly at its own will. I assume it to be a ground issue. Any suggestions as to where to start looking? Anyone know of common areas where grounds break loose and need reconnecetd? anything will help, thanks

Do you get an "EDC NOT ACTIVE" warning ?

Is the suspension very stiff all the time ?

These questions will help narrow down the search for the problem.

A check control warning means the edc has detected a fault from a sensor
or shock valve.
No warning but incorrect operation could be a variety of other issues.

Main issue with wiring is where the loom exits rear floor/firewall and travels
over the rear subframe...this is a known issue, the wiring chaffs & shorts here.

If you've exhausted all checks you can do yourself then have the
fault codes read.


Regards,


Alan.
