I am experiencing two seemingly unrelated but strange problems.

The first is the engine idle, it will not lower itself to normal speed, currently it idles @ 2,000 rpm. Engine cold or at normal temperature, makes no difference
Throttle linkage does not appear to be binding.
Second problem is whenever the motor experiences this high idle, the ABS warning light comes and stays on, this has me baffled.
This problem has been intermittent for maybe the past 2 months, but now is constant, the vehicle has become a hazard to drive

I have consulted the factory shop manual (CD form), to no avail.
Can anyone offer insight?

problem solved

Do a search on OVP or overvoltage protection relay.
Red cap, 10A fuse (or fuses).

Thank You sir, for your response.

I had consulted with the local M-B service dept. shop foreman and he advised that I check the exact same relay. He went on to say that I might get lucky and just have a blown fuse, but that was not the case. After replacing the component, the engine idle resumed normal speed and the ABS warning light extinguished.
Needless to say I am very much relieved, the vehicle is now safe to operate
One can only wonder what other strange problems this malfunctioning unit could of caused.

Regards,

Jeff Lee

In order to protect themselves from a high voltage the components shut down.
Clever thinking by the engineers.:thumbsup:
Glad it worked out and you reported back. This might help someone else, using the searchfunction, in the future.
