1.CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Check the terminals and connectors of the ABS actuator and electric unit (control unit) for damage, bend and loose connection (unit side and connector side).
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair the terminal and connector.
2.CHECK HARNESS FOR OPEN CIRCUIT
1. Disconnect the connector of ABS actuator and electric unit (control unit).
2. Check the resistance between the ABS actuator and electric unit (control
unit) harness connector terminals. 
Is the measurement value within the specification?
YES >> GO TO 3.
NO >> Repair the ABS actuator and electric unit (control unit) branch line.
3.CHECK POWER SUPPLY AND GROUND CIRCUIT
Check the power supply and the ground circuit of the ABS actuator and electric unit (control unit). Refer to BRC"Diagnosis Procedure".
Is the inspection result normal?
YES (Present error)>>Replace the ABS actuator and electric unit (control unit). Refer to BRC "Removal and Installation".
