Hydraulic Unit (Solenoid Valve Harness Resistance Test)

WARNING: This page is about a different car, the 1994 Mazda MX-3. However, it is still accessible from the selected car via links, so may be relevant.

Turn ignition off. Disconnect ABS control unit 12-pin connector. Measure resistance between ground and 1A (Violet wire), 1B (Yellow/Green wire), 1C (Blue/Orange wire) and 1D (Brown wire) terminals. See Figure . Resistance should be approximately 3 ohms. If resistance is not as specified, check wiring harness between hydraulic unit 8-pin connector and ABS control unit.
