MONITOR DESCRIPTION

For a short time after cold engine starts, the ECM transmits command signals to the Air Injection Control Driver (AID) to drive the air pump and the Air Switching Valve (ASV). The AID detects open and short circuits according to the voltages at the AID terminals to the air pump and ASV, and the circuit voltage of the AID power source, and transmits diagnostic information as a signal to the ECM.

If the Secondary Air Injection (AIR) system circuit or the AID itself malfunctions, the AID sends a malfunction signal (duty signal) as diagnostic information to the ECM (when the system is normal, a system normal signal is sent). The ECM sets the DTC based on the diagnostic information from the AID.

EXAMPLE:


  1. The duty ratio of the diagnostic signal from the AID is 0 or 100% (remains at 0 V or the same as battery voltage).

  2. The duty ratio of the diagnostic signal from the AID shows an impossible ratio (other than 0, 20, 40, 80 and 100%).

  3. The AID outputs the normal signal (normal duty signal: 80%) while the system is not operating.

MONITOR STRATEGY

Required Sensors/Components (Main) Air injection control driver
Required Sensors/Components (Related) Air switching valve assembly
Frequency of Operation Once per drive cycle

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 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 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 intelligent tester to the DLC3.

  4. Turn the ignition switch to ON.

  5. Turn the intelligent tester 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 intelligent tester on.

  9. Enter the following menus: Powertrain / Engine and ECT / Utility / Secondary 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 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.

    Intelligent Tester 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

    Tech Tips


    • 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.

INSPECTION PROCEDURE

CAUTION:

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

Tech Tips

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.
