CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM Shift Paddle Switch Circuit

DESCRIPTION

When moving the shift lever into the M position using the transmission control switch, it is possible to switch the shift range position between "1" (first range) and "7" (seventh range).

Shifting up "+" once raises one shift range position, and shifting down "-" lowers one shift range position.

  5. PERFORM INITIALIZATION

    Note


    • Performing reset memory will clear the learned values of both the yaw rate sensor (deceleration sensor 0 point calibration) and CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, yaw rate sensor 0 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

      • Skid control computer

      • Oil pressure sensor

      • Deceleration sensor

    • After performing reset memory, always perform yaw rate sensor (deceleration sensor 0 point) calibration first, and then CVT oil pressure calibration.

    • Always perform 0 point calibration with the vehicle on level ground.

    • Do not shake or vibrate the vehicle during 0 point calibration.


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

    2. Check that no DTC is stored.
