    *a

    Component without harness connected

    (Center Differential Lock Actuator)

    1. Disconnect the E1 differential lock shift actuator connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      3 (M1) - 2 (M2) Always 1.5 to 100 Ω

    NG

  2. 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
      G54-3 (M1) or E1-3 (M1) - G54-9 (M2) or E1-2 (M2) Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. CHECK HARNESS AND CONNECTOR (4 WHEEL DRIVE CONTROL ECU - DIFFERENTIAL LOCK SHIFT ACTUATOR AND NO. 1 TRANSFER INDICATOR SWITCH)


    1. Disconnect the G53 4 wheel drive control ECU connector.

    2. Disconnect the E1 differential lock shift actuator connector.

    3. Disconnect the E2 differential lock indicator switch connector.

    4. Disconnect the A7 skid control ECU (master cylinder solenoid) connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      G53-2 (RLY1) - E1-6 (RLY1) Always Below 1 Ω
      G53-1 (RLY2) - E1-5 (RLY2) Always Below 1 Ω
      E1-4 (GND2) - Body ground Always Below 1 Ω
      G53-12 (RLP) - E2-2 (+B) Always Below 1 Ω
      E2-1 (GND) - Body ground Always Below 1 Ω
      G53-2 (RLY1) or E1-6 (RLY1) - Body ground Always 10 kΩ or higher
      G53-1 (RLY2) or E1-5 (RLY2) - Body ground Always 10 kΩ or higher
      G53-12 (RLP) or E2-2 (+B) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  4. INSPECT DIFFERENTIAL LOCK SHIFT ACTUATOR (LIMIT SWITCH)


    1. Turn the ignition switch off.

    2. Remove the differential lock shift actuator Click here.

    3. Check the limit switch of the differential lock shift actuator Click here.


    NG

    REPLACE DIFFERENTIAL LOCK SHIFT ACTUATOR Click here

    OK

  5. INSPECT DIFFERENTIAL LOCK INDICATOR SWITCH


    1. Turn the ignition switch off.

    2. Remove the differential lock indicator switch Click here.

    3. Check the differential lock indicator switch Click here.

      OK
      The differential lock indicator switch is normally.

    OK
