Is fusible link OK?
Yes >>GO TO 3.
No >>GO TO 7.
3. CHECK FUSE
Check 10A fuse No. 45. 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 connectors from ABS actuator and electric unit (control unit). Check terminals for damage or loose connection. Then reconnect connectors.
2. Carry out self-diagnosis again.
Does warning lamp activate again?
Yes >>GO TO 5.
No >>INSPECTION END.
5. CHECK GROUND CIRCUIT
Is ground 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.
