CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM - Pattern Select Switch Sport Mode Circuit


DESCRIPTION

The ECM memory contains the programs for the normal and sport shift patterns.
By following the programs corresponding to the signals from the No. 1 pattern select switch assembly, the park/neutral position switch and other various sensors, the ECM switches the shift control solenoid valves on and off, and controls the transaxle gear ratio.

4.REPLACE ECM

  1. Replace the ECM (RAV4_ACA30 RM0000017UO01KX.html).

5.PERFORM INITIALIZATION
NOTICE:
  1. Performing reset memory will clear the learned values of both the yaw rate sensor assembly*1 or deceleration sensor*2 (deceleration sensor 0 point calibration) and CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, yaw rate sensor assembly*1 or deceleration sensor*2 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 sensor assembly (w/ VSC)
    5. Deceleration sensor (w/o VSC)
    6. Brake actuator assembly (skid control ECU)
  2. After performing reset memory, always perform yaw rate sensor assembly*1 or deceleration sensor*2 (deceleration sensor 0 point) calibration first, and then CVT oil pressure calibration.
  3. Always perform 0 point calibration with the vehicle on level ground.
  4. 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 (RAV4_ACA30 RM000003UQR002X.html).

  1. Check that no DTC is stored.
