Brake Pressure Modulator Valve

1. Ensure ignition switch is in Off position, then proceed as follows:
a. On models less Traction Control System (TCS), measure resistance between ground and ABS control unit connector terminals 1A, 1B, 1C and 1D, Fig. 116.

b. On models with TCS, measure resistance between ground and ABS control unit connector terminals 2V, 2W, 2Y and 2Z, Fig. 118.

2. If resistance is not approximately 3 ohms, inspect solenoid valves and wiring harness between ABS control unit and hydraulic unit connector. Repair as necessary.
3. On Millenia models, disconnect ABS hydraulic unit 8-pin connector, Fig. 119, then measure resistance between terminals A and E, B and F, C and G and, finally, D and H.
4. On 1995-96 Protege models, disconnect ABS hydraulic unit 8-pin connector, Fig. 119, then measure resistance between terminals A and H, B and G, C and F and, finally, D and E.
5. If resistance is not approximately 3 ohms, repair ABS hydraulic unit harness or replace unit as necessary.
