ABS Actuator Solenoid Valve or Solenoid Valve Relay

DIAGNOSTIC PROCEDURE
With CONSULT-II: Malfunction code No. C1114, C1120, C1121, C1122, C1123, C1124, C1125, C1126 or C1127
Without CONSULT-II: Malfunction code No. 41, 42, 45, 46, 51, 52, 55, 56, or 63

1. INSPECTION START





Solenoid valve relay inspection.

>> GO TO 2.

2. CHECK SOLENOID VALVE POWER SUPPLY CIRCUIT
Check 30A [h ] fusible link (ABS ACTR) for ABS solenoid valve relay. For fusible link layout, refer to "POWER SUPPLY ROUTING CIRCUIT".
Is fusible link OK?
YES >> GO TO 3.
NO >> GO TO 7.

3. CHECK FUSE
Check 10A fuse No. 49. For fuse layout, refer to "POWER SUPPLY ROUTING CIRCUIT".
Is fuse OK?
YES >> GO TO 4.
NO >> GO TO 9.

4. 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 warning lamp activate again?
YES >> GO TO 5.
NO >> Inspection End.

5. CHECK GROUND CIRCUIT
Refer to "ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND".
Is around circuit OK?
YES >> GO TO 6.
NO >> Repair harness and connectors.

6. CHECK SOLENOID VALVE 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 18 (Y) and ground.
Does battery voltage exist?
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 fusible link. If NG, repair harness or connectors.

7. REPLACE FUSIBLE LINK
Replace fusible link.
Does the fusible link blow when the ignition switch is turned ON?
YES >> GO TO 8.
NO >> Inspection End.

8. CHECK RELAY UNIT POWER SUPPLY CIRCUIT





1. Disconnect ABS actuator and electric unit (control unit) connector E125.
2. Check continuity between ABS actuator and electric unit (control unit) connector E125 terminal 18 (Y) and around.
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 >> Replace ABS actuator and electric unit (control unit). Refer to "Removal and Installation".

9. REPLACE FUSE
Replace fuse.
Does the fuse blow when the ignition switch is turned ON?
YES >> Check the following.
- Harness connector E125
- Harness for short between ABS actuator and electric unit (control unit) and fuse. If NG, repair harness or connectors.
NO >> Inspection End.
