MONITOR DESCRIPTION

This DTC indicates an open or short circuit in the circuit containing the air pump of the secondary air injection system. 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 Air Injection Check only allows technicians to operate the AIR 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 AIR system operation using the intelligent tester is prohibited, the intelligent tester display indicates the prohibition (WAIT or ERROR). If ERROR is displayed on the intelligent tester during the test, stop the engine for 10 minutes, and then try again.

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

  • When performing the Air Injection Check operation after the battery cable has been reconnected, wait for 7 minutes with the engine switch turned on (IG) or the engine running.

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

  1. Start the engine and warm it up.

  2. Turn the engine switch off.

  3. Connect the intelligent tester to the DLC3.

  4. Turn the engine switch on (IG).

  5. Turn the tester on.

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

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

  8. Turn the engine switch on (IG) and turn the tester on.

  9. Enter the following menus: Powertrain / Engine and ECT / Utility / Air injection check / Automatic Mode.

  10. Start the engine after the intelligent tester initialization is finished.

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

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

  13. Check for pending DTCs.

    OK

    No pending DTC is output.

  14. After "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.

CAUTION / NOTICE / HINT

Tip:

  • By using the intelligent tester to perform the Air Injection Check operation in the System Check, the air-fuel ratio and the pressure in the secondary air injection system passage can be checked while the secondary air injection system is operating. This helps technicians to troubleshoot the system when it malfunctions.

  • Read freeze frame data using the intelligent tester. 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.
