MONITOR DESCRIPTION

This DTC indicates an open or short circuit in the secondary air injection system circuit or a malfunction in the air injection control driver itself. The air injection control driver performs diagnosis of the air pump, air switching valve and itself, and sends the results of this diagnosis to the ECM as a duty signal. When the ECM receives a signal indicating a malfunction in the air pump, air switching valve or air injection control driver, it immediately illuminates the MIL and stores a DTC.

CONFIRMATION DRIVING PATTERN

Note:

  • This Secondary Air Injection Check only allows technicians to operate the secondary air injection system for a maximum of 5 seconds.

    Furthermore, the check can only be performed up to 4 times per trip. If the test is repeated, intervals of at least 30 seconds are required between checks.

    While secondary air injection system operation using the GTS is prohibited, the GTS display indicates the prohibition (WAIT or ERROR).

    If ERROR is displayed on the GTS during the test, stop the engine for 10 minutes, and then try again.

  • Performing the Secondary Air Injection Check repeatedly may cause damage to the secondary air injection system. If necessary, leave an interval of several minutes between System Check operations to prevent the system from overheating.

  • When performing the Secondary Air Injection Check operation after the battery cable has been reconnected, wait for 7 minutes with the ignition switch turned to ON or the engine running.

  • Turn the ignition switch off when the Secondary Air Injection Check operation finishes.


  1. Start the engine and warm it up.

  2. Turn the ignition switch off.

  3. Connect the GTS to the DLC3.

  4. Turn the ignition switch to ON.

  5. Turn the GTS on.

  6. Clear DTCs (even if no DTCs are stored, perform the clear DTC operation).

  7. Turn the ignition switch off and wait for at least 30 seconds.

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

  9. Enter the following menus: Powertrain / Engine and ECT / Utility / Secondary Air Injection Check / Automatic Mode.

  10. Start the engine after the GTS initialization is finished.

  11. Perform the System Check operation by pressing ENTER (Next).

  12. Perform the following to confirm the secondary air injection system pending codes: Press the ENTER (Exit).

  13. Check for pending DTCs.

    OK
    No pending DTC is output.

  14. After the "Secondary Air Injection Check" is completed, check for All Readiness by entering the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

  15. Input the DTC: P1613.

  16. Check the DTC judgment result.

    GTS 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
    Tip:

    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

  17. Turn the ignition switch off.

CAUTION / NOTICE / HINT

CAUTION:

Inspect the fuses for circuits related to this system before performing the following inspection procedure.

Tip:

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, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.
