Control Unit Connector Resistance 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.
- Turn ignition off. Verify ABS control unit connector is disconnected. Set DVOM on 2-k/ohm scale. Measure and record resistance between each of following ABS connector wire terminals. See PINPOINT TEST WSS-3 CIRCUIT IDENTIFICATION table.
- If ALL resistances are between 1600-2000 ohms, go to PINPOINT TEST WSS-5 . If any resistance is not within specification, go to PINPOINT TEST WSS-4 .
