Pump Motor

WARNING: This page is about a different car, the 1996 Mazda Protege and 1995 Mazda Protege. However, it is still accessible from the selected car via links, so may be relevant.
  1. 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.
    CAUTION: To avoid damaging pump, DO NOT allow pump to run for more than 2 seconds.
  2. Apply 12 volts across pump motor/hydraulic unit 2-pin connector terminals (use Black wire for ground). Pump motor should operate. If resistance is not as specified or pump motor does not operate, check wiring harness. If wiring harness is okay, replace hydraulic unit.
