Check the voltage between ABS actuator and electric unit (control unit) harness connector and ground.

2.

Check 30A fusible link (G).

3.

Check the continuity between ABS actuator and electric unit (control unit) harness connector and battery
positive terminal.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace damaged parts. (Check ABS earth bolt for tightness and corrosion.)

3.

CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND CIRCUIT

Check the continuity between ABS actuator and electric unit (control unit) harness connector and ground.
