Repair Procedures: Removal

NOTE: In case of replacing the controller (ECU) and transfer case due to changing characteristics of the frictional materials inside the transfer case, it is necessary to check and enter the calibration data.
  • In case of replacing the transfer case assembly only, perform the clutch learning reset in the ECU.

    (Refer to 4 Wheel Drive (AWD) system - "REPAIR PROCEDURES ")

  • In case of replacing the ECU only, perform the clutch learning back-up and writing in the new transfer case ECU using GDS equipment.

    (Refer to 4 Wheel Drive (AWD) system - "REPAIR PROCEDURES ")

NOTE: Cautions in handling the transfer case
  1. Preventing the oil leaking
    • Even with the ventil valve installed, oil leaks from the collected oil during disassembling/assembling procedures in case of failure of keeping the horizontal position. Therefore, use caution when replacing the transmission.

    NOTE:
    1. When retightening the propeller shaft mounting bolts after removing them, each bolt and washer must be placed in its original position and bolt insertion direction must be the same as before, so make marks not to allow the bolts and washers to be mixed up before removing the propeller shaft.
    2. If the position and direction of the propeller shaft mounting bolts and washers are reversed, it may cause vibration and noise at high vehicle speeds due to imbalance in the propeller shaft.
  8. Disconnect the actuator connector (A).
