PROCEDURE


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


    1. Disconnect the G54 4 wheel drive control ECU connector.

    2. Disconnect the E1 differential lock shift actuator connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      G54-3 (M1) - E1-3 (M1) Always Below 1 Ω
      G54-9 (M2) - E1-2 (M2) Always Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. INSPECT DIFFERENTIAL LOCK SHIFT ACTUATOR (DIFFERENTIAL LOCK SHIFT MOTOR)
