CONFIRMATION DRIVING PATTERN

CAUTION:

When performing the confirmation driving pattern, obey all speed limits and traffic laws.

HINT:

After repairs have been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

  1. Connect the Techstream to the DLC3.
  2. Turn the ignition switch to ON and turn the Techstream on.
  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  4. Turn the ignition switch off and wait for 2 minutes or more.
  5. Turn the ignition switch to ON and turn the Techstream on.
  6. Start the engine.
  7. Drive the vehicle at 2 km/h (1 mph) or more.
  8. Stop the vehicle.
  9. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
  10. Input the DTC: P1589.
  11. Check the DTC judgment result.

    Techstream Display

    Description

    NORMAL
    • DTC judgment completed
    • System normal

    ABNORMAL
    • DTC judgment completed
    • System abnormal

    INCOMPLETE
    • DTC judgment not completed
    • Perform driving pattern after confirming DTC enabling conditions

    N/A
    • Unable to perform DTC judgment
    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    HINT:

    • If the judgment result shows NORMAL, the system is normal.
    • If the judgment result shows ABNORMAL, the system has a malfunction.
    • If the judgment result shows INCOMPLETE or N/A, perform the Confirmation Driving Pattern and check the DTC judgment result again.

CAUTION / NOTICE / HINT

CAUTION:

  • Strictly observe posted speed, limits, traffic laws and road conditions.
  • Do not drive the vehicle with the cable of the Techstream contacting the pedals, shift lever or steering wheel.
  • Driving the vehicle with the cable of the Techstream contacting these areas could impede vehicle control, resulting in a serious accident.
  • Do not operate the Techstream while driving the vehicle.
  • Operating the Techstream while driving the vehicle will prevent you from paying sufficient attention to vehicle surroundings, and could result in a serious accident.

NOTICE:

  • Perform initialization when parts related to the continuously variable transaxle system are replaced.

PROCEDURE

1.

PERFORM INITIALIZATION (DECELERATION SENSOR ZERO POINT CALIBRATION)

NOTICE:

  • If CVT Oil Pressure Calibration is performed before Deceleration Sensor Zero Point Calibration, DTC P1589 will be stored. In this case, perform steps *1, *2, *3, *4 and *5 to return the system to normal.
  • Always perform calibration with the vehicle on level ground (Inclination: 0 +/- 0.25°).
  • Do not shake or vibrate the vehicle during calibration.

(a) Turn the ignition switch off.*1

(b) Move the shift lever to P and apply the parking brake.*2

(c) Connect the Techstream to the DLC3.

(d) Turn the ignition switch to ON.*3

NOTICE:

Do not start the engine.

(e) Enter the following menus: Powertrain / Engine and ECT / Utility / Reset Memory.*4

Powertrain > Engine and ECT > Utility

Tester Display

Reset Memory

(f) Enter the following menus: Powertrain / Engine and ECT / Utility / Deceleration Sensor Zero Point Calibration.*5

Deceleration Sensor Zero Point Calibration

HINT:

  • When "Complete" is displayed on the screen, Deceleration Sensor Zero Point Calibration is complete.
  • If "Error" is displayed on the screen, there may be a malfunction in the yaw rate and acceleration sensor (airbag sensor assembly) circuit.
  • Shaking or vibrating the vehicle during Deceleration Sensor Zero Point Calibration may cancel calibration. If "Error" is displayed on the screen, perform step *5 again.

(g) If "Error" is displayed on the Techstream, read the DTCs using the Techstream.

2.

PERFORM CVT OIL PRESSURE CALIBRATION

NOTICE:

Do not perform Reset Memory and clear the learned values.

(a) Turn the ignition switch off and wait at least 30 seconds.

(b) Connect the Techstream to the DLC3.

(c) Turn the ignition switch to ON and wait at least 2 seconds.

NOTICE:

Do not start the engine.

HINT:

CVT Oil Pressure Calibration is performed with the ignition switch ON (engine stopped). However, calibration cannot be performed under the following conditions:

  • Oil pressure sensor value is 0.065 MPa (0.663 kgf/cm2, 9.43 psi) or more.
  • CVT oil temperature is 0°C (32°F) or less or 120°C (248°F) or more.

(d) Start the engine and wait at least 5 seconds.

NOTICE:

  • Start the engine with the shift lever in P.
  • After starting the engine, do not operate the accelerator pedal.

(e) Enter the following menus: Powertrain / Engine and ECT / Utility / CVT Oil Pressure Calibration

Powertrain > Engine and ECT > Utility

Tester Display

CVT Oil Pressure Calibration

HINT:

  • When performing CVT Oil Pressure Calibration, the engine idle speed will increase.
  • When "Complete" is displayed on the screen, CVT Oil Pressure Calibration is complete.
  • The learned values cannot be cleared by only disconnecting and reconnecting the cable to the negative (-) battery terminal.

(f) Check for DTCs again.
