Is DTC C1164, C1165, C1166 or C1167 detected? YES >> Proceed to diagnosis procedure. Refer to BRC-85, "Diagnosis Procedure".
NO >> Inspection End.
Diagnosis Procedure
Regarding Wiring Diagram information, refer to BRC-44, "Wiring Diagram".
1.CONNECTOR INSPECTION
Turn ignition switch OFF.
Disconnect ABS actuator and electric unit (control unit) connector.
Check connector and terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal? YES >> GO TO 2.
NO >> Repair or replace as necessary.
2.Check abs actuator and electric unit (control unit) battery power supply
