MONITOR DESCRIPTION

For a short time a after cold engine start, the ECM transmits command signals to the air injection control driver to drive the air pump and air switching valve. The air injection control driver detects open and short circuits according to the voltages at the air injection control driver terminals connected to the air pump and air switching valve, and the circuit voltage of the air injection control driver power source, and transmits diagnostic information as a signal to the ECM.

If the Secondary Air Injection (AIR) system circuit or the air injection control driver itself malfunctions, the air injection control driver 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 stores the DTC based on the diagnostic information from the air injection control driver.

Example:


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

  2. The duty ratio of the diagnostic signal from the air injection control driver shows an impossible ratio (other than 0, 20, 40, 80 or 100%).

  3. The air injection control driver outputs the normal signal (normal duty signal: 80%) while the system is not operating.

INSPECTION PROCEDURE

Tech Tips

Diagnostic information output by the air injection control driver can be confirmed by connecting an oscilloscope to the diagnostic information terminal of the air injection control driver. Reading the waveform while performing the AIR system forced operation provided in the system check allows the possible trouble areas to be narrowed down.

Tech Tips


  • By using the intelligent tester 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 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.

PROCEDURE


  1. CHECK FOR ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P1613)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch to ON and turn the intelligent tester on.

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

    4. Read DTCs.

      Note


      • Do not perform the system check operation repetitively. It may cause the damage in the system. If it is necessary to repeat the check, leave an interval of several minutes between system check operations.

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

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