When either conditions below is met:
  1. Wheel speed sensor malfunction is received from skid control ECU
  2. Deceleration sensor malfunction us received from skid control ECU
  1. CAN communication line
  1. Skid control ECU
  1. Speed sensor
  1. 4WD control ECU
  1. Yaw rate sensor (Deceleration sensor)
  1. Wire harness

INSPECTION PROCEDURE

HINT:
Check the condition of each related circuit connector before troubleshooting (RAV4_ACA30 RM000000UZ306OX.html).
1.CHECK FOR DTC

  1. Clear the DTC (RAV4_ACA30 RM0000020BA00FX.html).

    Result
    Result
    		Proceed to
    Neither CAN communication system DTC brake control system DTC is not output
    		A
    CAN communication system DTC is output
    		B
    Brake control system DTC is output
    		C

HINT:
When DTCs indicating a CAN communication system malfunction are output, repair the CAN communication system before repairing each corresponding sensor.


B
REPAIR CIRCUIT INDICATOR BY OUTPUT CODE (CAN COMMUNICATION SYSTEM)

C

A


2.CHECK OPERATION OF 4WD CONTROL ECU

  1. Replace the 4WD control ECU with a normally functioning or new one.

    NOTICE:
    When performing inspections after replacing the 4WD control ECU with a normal one from another vehicle, be sure to perform zero point calibration of the yaw rate sensor by connecting terminals TS and CG of the DLC3 (RAV4_ACA30 RM000003GIS001X.html).
    HINT:
    Calibrate the 4WD control ECU by performing calibration of the vehicle stability control system.

  1. Reconfirm DTC.

    OK:
    DTC is not output.


OK
END (4WD CONTROL ECU FAULTY)
NG

GO TO BRAKE CONTROL SYSTEM (ANTI-LOCK BRAKE SYSTEM OR VEHICLE STABILITY CONTROL SYSTEM)
