    CHECK HARNESS AND CONNECTOR (SHIFT CONTROL ECU - RANGE SENSOR (SHIFT CONTROL ACTUATOR ASSEMBLY))


    1. Disconnect the A50 shift control ECU connector.

    2. Disconnect the D32 range sensor (shift control actuator assembly) connector.

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

      Standard Resistance (Check for Open)
      Tester Connection Condition Specified Condition
      A50-19 (VCNS) - D32-1 (VCNS) Always Below 1 Ω
      A50-20 (NS1) - D32-2 (NS1) Always Below 1 Ω
      A50-18 (NS2) - D32-4 (NS2) Always Below 1 Ω
      A50-17 (E2NS) - D32-3 (E2NS) Always Below 1 Ω
      Standard Resistance (Check for Short)
      Tester Connection Condition Specified Condition
      A50-19 (VCNS) or D32-1 (VCNS) - Body ground and other terminals Always 10 kΩ or higher
      A50-20 (NS1) or D32-2 (NS1) - Body ground and other terminals Always 10 kΩ or higher
      A50-18 (NS2) or D32-4 (NS2) - Body ground and other terminals Always 10 kΩ or higher
      A50-17 (E2NS) or D32-3 (E2NS) - Body ground and other terminals Always 10 kΩ or higher
