Inspection Procedure

WARNING: This page is about a different variant/trim than selected.
  1. INSPECT TRANSMISSION WIRE (SLT) 
    1. Disconnect the transmission wire connector from the transaxle.
    2. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      RESISTANCE SPECIFICATION

      Tester Connection Condition Specified Condition
      2 (SLT+) - 8 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
    3. Measure the resistance according to the value(s) in the table below.

      Standard resistance (Check for short) 

      RESISTANCE SPECIFICATION

      Tester Connection Condition Specified Condition
      2 (SLT+) - Body ground Always 10 kΩ or higher
      8 (SLT-) - Body ground Always

      NG: Go to step  3

      OK: Go to next step 

  2. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM) 
    1. Connect the transmission wire connector to the transaxle.
    2. Disconnect the ECM connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      RESISTANCE SPECIFICATION

      Tester Connection Condition Specified Condition
      B31-76 (SLT+) - B31-75 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
    4. Measure the resistance according to the value(s) in the table below.

      Standard resistance (Check for short) 

      RESISTANCE SPECIFICATION

      Tester Connection Condition Specified Condition
      B31-76 (SLT+) - Body ground Always 10 kΩ or higher
      B31-75 (SLT-) - Body ground Always

      NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

      OK: REPLACE ECM  (See REMOVAL )

  3. INSPECT SHIFT SOLENOID VALVE SLT 
    1. Remove the shift solenoid valve (SLT).
    2. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      RESISTANCE SPECIFICATION

      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 5.0 to 5.6 Ω
    3. Connect the positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector, then check the movement of the valve.

      OK: The solenoid makes an operating sound. 

      NG: REPLACE SHIFT SOLENOID VALVE SLT  (See DISASSEMBLY )
