The ABS warning light on my '94 850 is lit. When I run a diagnostic on the module it reas 4-2-2, Rear wheel circuit return valve: open circuit or short circu. How do I fix it?

Re: ABS Warning Light (gir)

There is a big black relay clipped by the ABS ECU under the hood. That relay supplies power to the ECU and is more than likely the culprit.<br>I would start there.<br>Also check the connector on the L/F strut tower for corrosion <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">

Why bother, it's your module.<br>That's what it always says but it's the module

That module is different. If it was a 1996 or 1997 i will agree with the module being bad.
