  1. Ignition switch ON and battery voltage is 10.5 V or more

  2. All of the following signals are OFF simultaneously


    • NSW position switch signal

    • P position switch signal

    • R position switch signal

    • N position switch signal

    • D position switch signal

  3. 60 seconds

  4. 2-trip detection logic


  1. Ignition switch ON and battery voltage is 10.5 V or more

  2. When any of following conditions is met and the M signal is ON


    • NSW position switch signal is ON

    • P position switch signal is ON

    • R position switch signal is ON

    • N position switch signal is ON

  3. 2 seconds

  4. 2-trip detection logic

MONITOR DESCRIPTION

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

When the park/neutral position switch assembly and shift lock control unit assembly (transmission control switch) send more than one signal at a time from switch positions P, R, N, D or M, the ECM interprets this as a fault in the switch. The ECM will turn on the MIL and store the DTC.

    Note


    • Performing reset memory/initialization will clear the learned value of the deceleration sensor (deceleration sensor zero point calibration) and the CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, deceleration sensor zero point calibration, and CVT oil pressure calibration when replacing any of the parts shown in the following table:

      Replaced Part

      • Continuously variable transaxle assembly

      • ECM

      • Brake actuator assembly (Skid control ECU)

      • Oil pressure sensor

      • Deceleration sensor

    • After reset memory, always perform deceleration sensor (deceleration sensor zero point) calibration first, and then the CVT oil pressure calibration.

    • Always perform the zero point calibration with the vehicle on level ground.

    • Do not shake or vibrate the vehicle during the zero point calibration.
