  2. Connect the Techstream to the DLC3.
  3. Turn the power switch on (IG) [B].
  4. Turn the Techstream on.
  5. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  6. Turn the power switch off and wait for at least 30 seconds.
  7. Turn the power switch on (IG) [C].
  8. Turn the Techstream on.
  9. Put the engine in Inspection Mode (Maintenance Mode).

    Click here 2019 - 2025 MY Corolla Corolla Hatchback Corolla HV GR Corolla [06/2018 -        ]; INTRODUCTION: REPAIR INSTRUCTION: INSPECTION MODE PROCEDURE

  10. Start the engine and wait 2 minutes [D].
  11. Warm up the engine until the engine coolant temperature is 75°C (167°F) or higher [E].
  12. Idle the engine for 1 minute [F].
  13. With the engine running, accelerate the vehicle to 80 km/h (50 mph) and stop the vehicle [G].

    CAUTION:

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

    HINT:

    If the engine stops, further depress the accelerator pedal to restart the engine.

  14. With the engine running, drive the vehicle at 60 to 80 km/h (37 to 50 mph) for 5 minutes or more [H].

    CAUTION:

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

    HINT:

    If the engine stops, further depress the accelerator pedal to restart the engine.

  15. Enter the following menus: Powertrain / Engine / Trouble Codes [I].
  16. Read the pending DTCs.

    HINT:

    • If a pending DTC is output, the system is malfunctioning.
    • If a pending DTC is not output, perform the following procedure.
  17. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  18. Input the DTC: P060796, P013611, P013613, P013614, P013615, P013617 or P013623.
  19. 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

    HINT:

    • If the judgment result is NORMAL, the system is normal.
    • If the judgment result is ABNORMAL, the system is malfunctioning.
    • If the judgment result is INCOMPLETE, perform steps [E] through [I] again.
    • [A] to [I]: Normal judgment procedure.

      The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

    • When clearing the permanent DTCs, do not disconnect the cable from the auxiliary battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.

CAUTION / NOTICE / HINT

NOTICE:

  • Vehicle Control History may be stored in the hybrid vehicle control ECU if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the freeze frame data and Vehicle Control History can be useful for troubleshooting.

  • If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.

HINT:

Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE

1.

CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P060796)

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / Engine / Trouble Codes.

(e) Read the DTCs.

INSPECT DTC (P013611, P013613, P013614, P013615, P013617 OR P013623)

(a) Refer to the P013611, P013613, P013614, P013615, P013617 or P013623 flowchart.

HINT:

  • If P013611, P013613, P013614, P013615, P013617 or P013623 is output, troubleshoot for that DTC first. Then proceed to "Inspect ECM".

Inspection Mode

(e) Start the engine.

(f) Allow the engine to idle, and then rev the engine.

(g) Check for exhaust gas leaks around the heated oxygen sensor.

If any exhaust gas leaks are present, repair them and proceed to "Perform Confirmation Driving Pattern". If no exhaust gas leaks are present, proceed to "Perform Confirmation Driving Pattern".

HINT:

  • If no exhaust gas leaks are present, there may be a malfunction in the heated oxygen sensor circuit.
  • If any exhaust gas leaks are present around the heated oxygen sensor, noise appears in the output voltage of the heated oxygen sensor.
  • Perform "Inspection After Repair" after repairing or replacing the exhaust system.
