Motor Relay
- Turn ignition off. Disconnect ABS Control Module (ABS CM) connector. See COMPONENT LOCATIONS
. Connect Adapter Harness (49-F066-002) to ABS CM connector. Turn ignition on. Using voltmeter, measure voltage between terminals "X" and AB of ABS CM connector. See Figure
. Voltage should be zero volts. Apply 12 volts to terminal "B" an d ground terminal "G" of ABS CM connector. Using voltmeter, measure voltage between terminals "X" and AB of ABS CM connector. Voltage should be 12 volts. If voltage is not as specified, check wiring harness. If wiring harness is okay, go to next step.
- Remove motor relay from hydraulic unit. See Figure
. Using ohmmeter, check continuity between terminals "B" and "C" of motor relay. See Fig 1
. Continuity should exist. Apply 12 volts to terminal "C" and ground terminal "B". Using ohmmeter, check continuity between terminals "A" and "D" of motor relay. Continuity should exist. If continuity is not as specified, replace motor relay.
