Pump Motor
- Turn ignition off. Disconnect ABS Control Module (ABS CM) connector. See COMPONENT LOCATIONS . Connect Adapter Harness (49-F066-002) to ABS CM connector. Using ohmmeter, measure resistance between terminal "X" of ABS CM connector and ground. See Figure . Resistance should not be more than one ohm. If resistance is not as specified, check wiring harness between ABS CM and pump motor. See WIRING DIAGRAMS . If wiring harness is okay, go to next step.
- Turn ignition off. Disconnect pump motor/hydraulic unit 2-pin connector. Using ohmmeter, measure resistance between terminal "B" of pump motor/hydraulic unit connector and ground. See Fig 1 . Resistance should not be more than one ohm. Apply 12 volts across pump motor/hydraulic unit 2-pin connector terminals. 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.
