Inspection Procedure

  1. DATA LIST 

    HINT:

    Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

    NOTE: In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
    1. Warm up the engine.
    2. Turn the engine switch off.
    3. Connect the Techstream to the DLC3.
    4. Turn the engine switch on (IG) position.
    5. Turn the Techstream on.
    6. Select the item "Powertrain / Engine and ECT / Data List".
    7. According to the display on the tester, read the "Data List".
      DATA LIST

      Item Measurement Item/Range (display) Normal Condition Diagnostic Note
      Neutral Position SW Signal PNP Switch Status/ ON or OFF Shift lever position is; P and N: ON Except P and N: OFF When shift lever position displayed on the Techstream differs from actual position, adjustment of PNP switch or shift cable may be incorrect
      Shift SW Status (R Range) PNP Switch Status/ ON or OFF Shift lever position is; R: ON Except R: OFF ↑
      Shift SW Status (P Range) PNP Switch Status/ ON or OFF Shift lever position is; P: ON Except P: OFF ↑
      Shift SW Status (N Range) PNP Switch Status/ ON or OFF Shift lever position is; N: ON Except N: OFF ↑
      Shift SW Status (D Range) PNP Switch Status/ ON or OFF Shift lever position is; D and S: ON Except D and S: OFF ↑
      Sports Mode Selection SW Sport Mode Select Switch Status/ ON or OFF Shift lever position is; S, "+" and "-": ON Except S, "+" and "-": OFF -
  1. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY 
    1. Disconnect the park/neutral position switch connector.
    2. Measure resistance according to the value(s) in the table below when the shift lever is moved to each position.

      Standard resistance 

      TESTER CONNECTION SPECIFIED CONDITION CHART

      Shift Position Tester Connection Specified Condition
      P 2 - 6 and 4 - 5 Below 1 Ω
      Except P ↑ 10 kΩ or higher
      R 1-2 Below 1 Ω
      Except R ↑ 10 kΩ or higher
      N 2-9 and 4-5 Below 1 Ω
      Except N ↑ 10 kΩ or higher
      D, S, "+" and "-" 2-7 Below 1 Ω
      Except D, S, "+" and "-" ↑ 10 kΩ or higher

    NG: REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY 

    OK: Go to next step 

  2. INSPECT TRANSMISSION CONTROL SWITCH 
    1. Connect the park/neutral position switch connector.
    2. Disconnect the transmission control switch connector of shift lock control unit assembly.
    3. Measure resistance according to the value(s) in the table below when the shift lever is moved to each position.

      Standard resistance

    NG: REPLACE TRANSMISSION CONTROL SWITCH 

    OK: Go to next step 

  3. CHECK HARNESS AND CONNECTOR (PARK/NEUTRAL POSITION SWITCH - ECM) 
    1. Connect the transmission control switch connector of shift lock control unit assembly.
    2. Turn the engine switch on (IG) position, and measure the voltage according to the value(s) in the table below when the shift lever is moved to each position.

      Standard voltage 

      TESTER CONNECTION SPECIFIED CONDITION CHART

      Shift Position Tester Connection Specified Condition
      P and N E4-4 (STAR) - Body ground Below 1 V
      Except P and N ↑ 10 to 14 V

    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  4. CHECK HARNESS AND CONNECTOR (PARK/NEUTRAL POSITION SWITCH - ECM) 
    1. Disconnect the ECM connector.
    2. Turn the engine switch on (IG) position, and measure the voltage according to the value(s) in the table below when the shift lever is moved to each position.

      Standard voltage 

      TESTER CONNECTION SPECIFIED CONDITION CHART

      Shift Position Tester Connection Specified Condition
      P E4-6 (P) - Body ground 10 to 14 V
      Except P ↑ Below 1 V
      N E4-32 (N) - Body ground 10 to 14 V
      Except N ↑ Below 1 V
      R E4-8 (R) - Body ground 10 to 14 V*
      Except R ↑ Below 1 V
      D and S E4-9 (D) - Body ground 10 to 14 V
      Except D and S ↑ Below 1 V
      S, "+" and "-" A6-9 (S) - Body ground 10 to 14 V
      Except S, "+" and "-" ↑ Below 1 V
      HINT:
      *: The voltage will drop slightly due to the turning on of the back up light.

    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: REPLACE ECM
