INSPECTION PROCEDURE

PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SLU)


    1. A01EIZDE07

      Remove the TCM from the transaxle.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      11 (SLU+) - 5 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω
      11 (SLU+) - Body ground or other terminals Always 10 kΩ or higher
      5 (SLU-) - Body ground or other terminals Always 10 kΩ or higher
      11 (SLU+) - All other terminals except 5 (SLU-) Always 10 kΩ or higher
      5 (SLU-) - All other terminals except 11 (SLU+) Always 10 kΩ or higher

  2. INSPECT SHIFT SOLENOID VALVE SLU


    1. A01ELLFE01
      Text in Illustration
      *1 Shift Solenoid Valve SLU

      Remove shift solenoid valve SLU.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 5.0 to 5.6 Ω

    3. Connect a battery positive (+) lead with a 21 W bulb to terminal 2 and a negative (-) lead to terminal 1 of the solenoid valve connector. Then check that the valve moves and makes an operating sound.

      OK
      Valve moves and makes an operating sound.
