Table 1. DTC Detection Drive Pattern

DTC No.

DTC Detection Drive Pattern

P0089

Ignition switch ON

P0604

One of following conditions is met:

  • Ignition switch ON

  • Engine idling

  • Vehicle being driven in a stop-and-go city drive pattern for more than 15 minutes.

P0606

P0607

P060A

P060D

P062F

P06DD

Engine idling

P1607

One of following conditions is met:

  • Ignition switch ON

  • Engine idling

  • Vehicle being driven in a stop-and-go city drive pattern for more than 15 minutes.

CAUTION / NOTICE / HINT

Note:

When replacing the ECM, perform ECM Initialization and Registration.

Tip:

  • When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing a new ECM, perform all of the initialization and registration procedures for the "Learning Values Write" function by following the instructions shown on the GTS display.

  • Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

PROCEDURE

  2. CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS on.

    3. Clear the DTCs.

      Powertrain > Engine and ECT > Clear DTCs

    4. Turn the ignition switch off and wait for 30 seconds or more.

    5. Turn the ignition switch to ON.

    6. Start the engine.

    7. Drive the vehicle with a stop-and-go city drive pattern for more than 15 minutes.

      CAUTION:

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

    8. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes / Pending.

    9. Confirm that the pending DTC is not output again.

      Powertrain > Engine and ECT > Trouble Codes
