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 termi-
nals.

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-2, "Wiring Diagram"

.

Is the inspection result normal?

YES (Present error)>>Replace the ABS actuator and electric unit (control unit).
YES (Past error)>>Error was detected in the ABS actuator and electric unit (control unit) branch line.
NO

>> Repair the power supply and the ground circuit.
