7.REPLACE ECM

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

8.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.
