PROCEDURE


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


    1. Disconnect the A27 4 wheel drive control ECU connector.

    2. for Automatic Transmission w/ Entry and Start System:

      Disconnect the V9 center differential lock switch (integration control and panel assembly) connector.

    3. except Automatic Transmission w/ Entry and Start System:

      Disconnect the G12 center differential lock switch connector.

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

      Standard Resistance
      for Automatic Transmission w/ Entry and Start System:
      Tester Connection Condition Specified Condition
      A27-14 (DL) - V9-9 (CPU) Always Below 1 Ω
      V9-5 (E) - Body ground Always Below 1 Ω
      A27-14 (DL) or V9-9 (CPU) - Body ground Always 10 kΩ or higher
      except Automatic Transmission w/ Entry and Start System:
      Tester Connection Condition Specified Condition
      A27-14 (DL) - G12-4 (CPU) Always Below 1 Ω
      G12-1 (E) - Body ground Always Below 1 Ω
      A27-14 (DL) or G12-4 (CPU) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. INSPECT INTEGRATION CONTROL AND PANEL ASSEMBLY OR CENTER DIFFERENTIAL LOCK SWITCH
