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 a signal to the TCM according to the shift lever position (P, N, R, D or M).

The TCM determines that there is a problem with the switch or related parts if it receives more than 1 position signal simultaneously. The TCM will illuminate the MIL and store the DTC.

PROCEDURE


  1. READ VALUE USING GTS


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / ECT / Data List / Shift SW Status (P Range), Shift SW Status (R Range), Shift SW Status (N Range), Shift SW Status (D Range).

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


      Powertrain > ECT > Data List
      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Shift SW Status (P Range) Park/neutral position switch status ON or OFF

      • ON: Shift lever in P

      • OFF: Shift lever not in P

      		 When the shift lever position displayed on the GTS differs from the actual position, adjustment of the park/neutral position switch assembly or shift cable may be incorrect
      Shift SW Status (R Range) Park/neutral position switch status ON or OFF

      • ON: Shift lever in R

      • OFF: Shift lever not in R

      		 When the shift lever position displayed on the GTS differs from the actual position, adjustment of the park/neutral position switch assembly or shift cable may be incorrect
      Shift SW Status (N Range) Park/neutral position switch status ON or OFF

      • ON: Shift lever in N

      • OFF: Shift lever not in N

      		 When the shift lever position displayed on the GTS differs from the actual position, adjustment of the park/neutral position switch assembly or shift cable may be incorrect
      Shift SW Status (D Range) Park/neutral position switch status ON or OFF

      • ON: Shift lever in D or M

      • OFF: Shift lever not in D or M

      		 When the shift lever position displayed on the GTS differs from the actual position, adjustment of the park/neutral position switch assembly or shift cable may be incorrect

      *a

      Component without harness connected

      (Park/Neutral Position Switch Assembly)

      Disconnect the park/neutral position switch assembly connector.

    2. Measure the resistance of the park/neutral position switch assembly when the shift lever is moved to each position.

      Standard Resistance
      Tester Connection Condition Specified Condition
      6 (PL) - 2 (RB) Shift lever in P Below 1 Ω
      1 (RL) - 2 (RB) Shift lever in R Below 1 Ω
      9 (NL) - 2 (RB) Shift lever in N Below 1 Ω
      7 (DL) - 2 (RB) Shift lever in D or M Below 1 Ω
      6 (PL) - 2 (RB) Shift lever not in P 10 kΩ or higher
      1 (RL) - 2 (RB) Shift lever not in R 10 kΩ or higher
      9 (NL) - 2 (RB) Shift lever not in N 10 kΩ or higher
