DTC 53 - Motor Relay Circuit

NOTE: If after all testing procedures have been completed system is not functioning properly, substitute ECU with known-good unit and retest.
  1. Using scan tool, perform Hydraulic Unit (HU) actuator test. If motor is not operating, go to next step. If motor is still operating, repair wiring harness between hydraulic unit and ECU. See WIRING DIAGRAM .
  2. Inspect motor relay. If relay is okay, Disconnect relay 4-pin connector. Using a DVOM, check voltage between 4-pin connector terminal No. 3 and ground. See Fig 1. If battery voltage is present, go to next step. If battery voltage is not present, check and repair wiring harness between ABS motor relay and fusible link No. 9. See WIRING DIAGRAM .
  3. Turn ignition off. Disconnect ECU connectors. Check voltage between ECU connector terminal No. 7 and ground. If battery voltage is present, replace ECU. If battery voltage is not present, check and repair connectors and related wiring harness between ABS motor relay and ECU. See WIRING DIAGRAM .
