CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM Shift Paddle Switch Circuit

DESCRIPTION

When the shift lever is in M, the shift range can be changed using the shift paddle switches. It is also possible to select the shift range when the vehicle is being driven with the shift lever in D by operating the shift paddle switches.

   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 Oil pressure sensor Yaw rate 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 (inclination: 0 +/-0.25°).

   • 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.
