MONITOR DESCRIPTION

This DTC indicates a problem with the park/neutral position switch assembly or the wire harness in the park/neutral position switch assembly circuit.
The park/neutral position switch assembly detects the shift lever position and sends signals to the TCM.
For safety, 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 signals to the TCM according to the shift lever position (P, N, R or D).
The TCM determines that there is a problem with the switch or related parts if a malfunction occurs in the park/neutral position switch signal. The TCM will illuminate the MIL and store the DTC.

INSPECTION PROCEDURE

NOTICE:
  1. Perform registration and/or initialization when parts related to the automatic transmission are replaced (Click here).
  2. Inspect the fuses for circuits related to this system before performing the following inspection procedure.
HINT:
After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.
  1. Turn the engine switch on (IG).*1
  2. Wait with the shift lever in each position (P, R, N and D) for 5 seconds or more.*2
  3. Drive the vehicle 30 km/h (19 mph) or more for 30 seconds or more.*3
  4. Turn the engine switch off.
  5. Perform steps (*1) through (*3) again.
  6. Check for DTCs again (Click here).

3.READ VALUE USING GTS (SHIFT SW STATUS)

  1. Connect the GTS to the DLC3.

  1. Turn the engine switch on (IG).

  1. Turn the GTS on.

  1. Enter the following menus: Powertrain / ECT / Data List.

  1. According to the display on the GTS, read the Data List.

    ECT
    Tester Display
    		Measurement Item/Range
    		Normal Condition
    		Diagnostic Note
    Shift SW Status (P Range)
    		Park/neutral position switch status/
    ON or OFF
    1. ON: Shift lever is in P
    2. OFF: Shift lever is not in P
    		When shift lever position displayed on the GTS differs from actual position, adjustment of park/neutral position switch assembly or shift cable may be incorrect.
    Shift SW Status (R Range)
    		Park/neutral position switch status/
    ON or OFF
    1. ON: Shift lever is in R
    2. OFF: Shift lever is not in R
    		When shift lever position displayed on the GTS differs from actual position, adjustment of park/neutral position switch assembly or shift cable may be incorrect.
    Shift SW Status (N Range)
    		Park/neutral position switch status/
    ON or OFF
    1. ON: Shift lever is in N
    2. OFF: Shift lever is not in N
    		When shift lever position displayed on the GTS differs from actual position, adjustment of park/neutral position switch assembly or shift cable may be incorrect.
    Shift SW Status (D Range)
    		Park/neutral position switch status/
    ON or OFF
    1. ON: Shift lever is in D or S
    2. OFF: Shift lever is not in D or S
    		When shift lever position displayed on the GTS differs from actual position, adjustment of park/neutral position switch assembly or shift cable may be incorrect.
