TROUBLE DIAGNOSIS
Note 1: After completing repairs of shorted sensor circuit, when turning ignition switch ON, ABS warning lamp turned on. Make t
hat ABS
warning lamp turned off while driving vehicle at approximately 30 km/h (19 MPH) or more for approximately 1 minute according to self-
diagnosis procedure. In addition, if whee l sensor 2 is displayed for wheels, check wheel sensor circuit and also check ABS actu ator and
electric unit (control unit) power voltage.
Note 2: If multiple malfunctions are detected including CAN communication line [U1000], perform diagnosis for CAN communication line
first.
Note 3: “ACTUATOR RLY” on the CONSULT-III self-diagnostic results indicates the malfunction of actuator relay or circuit. Actua tor relay
is imbedded in ABS actuator and electric unit (control unit).
Note 4:Only AWD models.
