DESCRIPTION

Using shift solenoid DS1 (inflow to the primary pulley) and shift solenoid DS2 (outflow from the primary pulley), the ECM controls the line pressure and fluid volume input and output to the primary pulley according to the vehicle speed and accelerator pedal angle. As a fail-safe function, if a solenoid is shorted or open, the ECM stops current to the faulty solenoid.

DTC No.

MONITOR DESCRIPTION

These DTCs indicate an open or short in the shift solenoid DS1 or DS2 circuit. When there is an open or short circuit in any shift solenoid valve circuits, the ECM detects the problem, illuminates the MIL and stores the DTC.

INSPECTION PROCEDURE

1.PERFORM ACTIVE TEST USING INTELLIGENT TESTER (CONTROL THE SHIFT POSITION)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON.

  1. Turn the tester on.

  1. Enter the following menus: Powertrain / Engine and ECT / Active Test.

  1. In accordance with the display on the tester, perform the Active Test.

5.PERFORM INITIALIZATION

NOTICE:
  1. Performing reset memory/initialization will clear the learned values of both the yaw rate and acceleration sensor (deceleration sensor 0 point calibration) and the CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, yaw rate and acceleration sensor 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 and acceleration sensor
  2. After reset memory, always perform yaw rate and acceleration sensor (deceleration sensor 0 point) calibration first, and then the CVT oil pressure calibration.
  3. Always perform the 0 point calibration with the vehicle on level ground.
  4. Do not shake or vibrate the vehicle during the 0 point calibration.

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