DTC P2763 Torque Converter Clutch Pressure Control Solenoid Control Circuit High (Shift Solenoid Valve DSU)

DTC P2764 Torque Converter Clutch Pressure Control Solenoid Control Circuit Low (Shift Solenoid Valve DSU)


DESCRIPTION

The ECM controls the signal to shift solenoid valve DSU and performs lock-up clutch pressure control in response to the input torque value.

P2763
  1. The vehicle is being driven.
  2. There is an open circuit in the shift solenoid valve DSU circuit.
  3. Detected 20 times or more consecutively
  4. 1 trip detection logic
  1. Open in shift solenoid valve DSU circuit
  2. Continuously variable transaxle assembly
  3. ECM
P2764
  1. The vehicle is being driven.
  2. There is a short circuit in the shift solenoid valve DSU circuit.
  3. Detected 20 times or more consecutively
  4. 1 trip detection logic
  1. Short in shift solenoid valve DSU circuit
  2. Continuously variable transaxle assembly
  3. ECM

MONITOR DESCRIPTION

These DTCs indicate an open or short circuit in the shift solenoid valve DSU circuit. The ECM controls lock-up by turning shift solenoid valve DSU on/off. When there is an open or short circuit in the shift solenoid valve DSU circuit, the ECM detects the problem, illuminates the MIL and stores the DTC.

3.REPLACE ECM

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

4.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.
