ABS/TCS

Motor Relay or Motor

DIAGNOSTIC PROCEDURE
With CONSULT-II: Malfunction code No. C1111
Without CONSULT-II: Malfunction code No. 61

1. INSPECTION START





ABS motor relay inspection.

>> GO TO 2.

2. CHECK MOTOR POWER SUPPLY CIRCUIT
Check 30A [g ] fusible link (ABS MTR) for ABS motor relay. For fusible link layout, Refer to "POWER SUPPLY ROUTING CIRCUIT".
Is fusible link OK?
YES >> GO TO 3.
NO >> GO TO 6.

3. CHECK CONNECTOR
1. Disconnect ABS actuator and electric unit (control unit) connector E125. Check terminals for deformation; disconnection, looseness or damage. Then reconnect connector.
2. Repeat self-diagnosis.
Does ABS warning lamp activate again?
YES >> GO TO 4.
NO >> Inspection End.

4. CHECK MOTOR RELAY POWER SUPPLY CIRCUIT
1. Disconnect ABS actuator and electric unit (control unit) connector E125.





2. Check voltage between ABS actuator and electric unit (control unit) connector E125 terminal 17 (B/Y) and ground.
Does battery voltage exist?
YES >> GO TO 5.
NO >> Check the following.
- Harness connector E125
- Harness for open or short between ABS actuator and electric unit (control unit) and fusible link. If NG, repair harness or connectors.

5. CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND CIRCUIT
Refer to "ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND".
Is ground circuit OK?
YES >> Replace ABS actuator and electric unit (control unit). Refer to Removal and Installation".
NO >> Check the following.
- Harness connector E125
- Harness for open or short between ABS actuator and electric unit (control unit) and ground. If NG, repair harness or connectors.

6. REPLACE FUSIBLE LINK
Replace fusible link.
Does the fusible link blow when the ignition switch is turned ON?
YES >> GO TO 7.
NO >> Inspection End.

7. CHECK ABS ACTUATOR MOTOR POWER SUPPLY CIRCUIT
1. Disconnect battery cable and ABS actuator and electric unit (control unit) connector E125.





2. Check continuity between ABS actuator and electric unit (control unit) connector E125 terminal 17 (B/Y) and ground. Does continuity exist?
YES >> Check the following.
- Harness connector E125
- Harness for short between ABS actuator and electric unit (control unit) and fusible link. If NG, repair harness or connectors.
NO >> Check ABS actuator and electric unit (control unit) pin terminals for damage and the connection of ABS actuator and electric unit (control unit) harness connector. Reconnect ABS actuator and electric unit (control unit) harness connector. Then retest.
