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 assembly, emission control valve set 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 assembly, emission control valve set or air injection control driver assembly, it immediately illuminates the MIL and stores a DTC.

INSPECTION PROCEDURE

Tech Tips


  • By using the GTS to perform the Secondary 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 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.

PROCEDURE


  1. CHECK AIR INJECTION CONTROL DRIVER ASSEMBLY (POWER SOURCE CIRCUIT)

      Front view of wire harness connector

      (to Air Injection Control Driver Assembly)

      Disconnect the air injection control driver assembly connector.

    2. Connect terminals DI and SIV of the wire harness connector for the air injection control driver assembly.

    3. Connect the GTS to the DLC3.

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

    5. Enter the following menus: Powertrain / Engine and ECT / Utility / Secondary Air Injection Check / Manual Mode / AIR PUMP: ON, ASV 1: OPEN, ASV 2: OPEN.

      Tech Tips

      When Manual Mode is selected, the GTS initialization (atmospheric pressure measurement) is performed automatically. The initialization takes 10 seconds. After the initialization, AIR PUMP and ASV operation can be selected.

    6. Start the engine.

    7. Perform the secondary air injection system forced operation while the engine is idling.

    8. Measure the voltage between the SIV and E terminals of the ECM connector when the secondary air injection system is ON and OFF.

    9. Turn the ignition switch off.

      Note


      • Performing Secondary 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 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.
