Solenoid Valve (SV) Signal Check
WARNING: This page is about a different car, the 1994 Mercury Tracer, 1994 Ford Probe, and 1994 Ford Escort. However, it is still accessible from the selected car via links, so may be relevant.
Ensure ABS control unit is connected. Turn ignition on. Set DVOM on 20-volt scale. Measure voltage between ground and ABS control unit connector Yellow wire (Escort and Tracer) or Yellow/White wire (Probe). If voltage is momentarily more than 10 volts, go to PINPOINT TEST SV-3 . If voltage is not as specified, repair Yellow wire (Escort and Tracer) or Yellow/White wire (Probe) between ABS relay and ABS control unit.
