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
Is the inspection result normal?
YES (Present error)>>Replace the ABS actuator and electric unit (control unit). Refer to
.
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.
