WARNING: This page is about a different car, the 1996 Mazda Millenia and 1995 Mazda Millenia. However, it is still accessible from the selected car via links, so may be relevant.
- Turn ignition off. Disconnect pump motor/hydraulic unit 2-pin connector. Using ohmmeter, measure resistance between terminals of pump motor/hydraulic unit connector. Resistance should not be more than one ohm. Apply 12 volts to pump motor/hydraulic unit 2-pin connector.
- Pump motor should operate. If resistance is not as specified or pump motor does not operate, check wiring harness. See WIRING DIAGRAMS . Repair wiring harness as necessary. If wiring harness is okay, replace hydraulic unit.
