MONITOR DESCRIPTION

This DTC indicates a problem with the park/neutral position switch assembly and the wire harness in the park/neutral position switch assembly circuit.

The park/neutral position switch assembly detects the shift lever position and sends a signal to the ECM.

For security, the park/neutral position switch assembly detects the shift lever position so that the engine can be started only when the shift lever is in P or N.

The park/neutral position switch assembly sends a signal to the ECM according to the shift lever position (R, N, D or S). The ECM determines that there is a problem with the switch or related parts if it receives more than 1 position signal simultaneously. The ECM will then illuminate the MIL and store this DTC.

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

  2. Turn the engine switch on (IG) and turn the GTS on.

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure) Click here.

  4. Turn the engine switch off and wait for at least 30 seconds.

  5. Turn the engine switch on (IG) and turn the GTS on.

  6. Move the shift lever to R and wait 2 seconds or more.

CAUTION / NOTICE / HINT


  1. DATA LIST

    Tech Tips

    Using the GTS 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 GTS to the DLC3.

    4. Turn the engine switch on (IG).

    5. Turn the GTS on.

    6. Enter the following menus: Powertrain / Engine / Data List / Powertrain / Engine / Data List / AT / Neutral Position SW Signal, Shift SW Status (R Range), Shift SW Status (D Range) and Sports Mode Selection SW.

    7. According to the display on the GTS.
