MONITOR DESCRIPTION

For security, the park/neutral position switch detects the gearshift position so that engine can be started only when the vehicle is in the P or N shift position.
When the park/neutral position switch and shift lock control unit assembly (transmission control switch) send more than one signal at a time from switch positions P, R, N, D, S (SDSW) or B, the ECM interprets this as a fault in the switch. The ECM will turn on the MIL and store the DTC.

6.PERFORM INITIALIZATION

NOTICE:
  1. Performing reset memory/initialization will clear the learned values of both the yaw rate and acceleration sensor (deceleration sensor 0 point calibration) and the CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, yaw rate and acceleration sensor 0 point calibration, and CVT oil pressure calibration when replacing any of the parts shown in the following table:
    Replaced Part
    1. Continuously variable transaxle assembly
    2. ECM
    3. Oil pressure sensor
    4. Yaw rate and acceleration sensor
  2. After reset memory, always perform yaw rate and acceleration sensor (deceleration sensor 0 point) calibration first, and then the CVT oil pressure calibration.
  3. Always perform the 0 point calibration with the vehicle on level ground.
  4. Do not shake or vibrate the vehicle during the 0 point calibration.

  1. Using the intelligent tester, perform the reset memory, deceleration sensor 0 point calibration and CVT oil pressure calibration (Click here).
