PROCEDURE


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


    1. Disconnect the C40 4 wheel drive control ECU connector.

    2. Disconnect the C7 A.D.D. actuator (differential motor actuator assembly) connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      C40-2 (DM1) - C7-1 (DM1) Always Below 1 Ω
      C40-6 (DM2) - C7-2 (DM2) Always Below 1 Ω
      Result
      Proceed to
      OK
      NG

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. INSPECT DIFFERENTIAL MOTOR ACTUATOR ASSEMBLY (A.D.D. SHIFT MOTOR)
