PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (4 WHEEL DRIVE CONTROL ECU - TRANSFER SHIFT ACTUATOR ASSEMBLY)


    1. Disconnect the C60 4 wheel drive control ECU connector.

    2. Disconnect the C74 transfer shift actuator assembly connector.

    3. w/o VSC:

      Disconnect the A68 skid control ECU (brake actuator assembly) connector.

      w/ VSC:

      Disconnect the A4 skid control ECU (brake actuator assembly) connector.

    4. for 1GD-FTV, 2GD-FTV:

      Disconnect the C41 ECM connector.

      for 1GR-FE:

      Disconnect the G144 ECM connector.

      for 2TR-FE:

      Disconnect the G143 ECM connector.

      for 1KD-FTV (Automatic Transmission):

      Disconnect the G146 TCM connector.

    5. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      C60-3 (4WDL) - C74-9 (L4) Always Below 1 Ω
      C74-10 (GND) - Body ground Always Below 1 Ω
      C60-3 (4WDL) or C74-9 (L4) - Body ground Always 10 kΩ or higher
