If necessary, leave an interval of Standard: AIR PUMP OPERATIONS ASV OPERATIONS EXHAUST GAS PULSATION ON OFF Not detected ON ON Detected (b) Other inspection method: The ASV operation can be confirmed by checking the cumulative pressure pulsation* provided in the System Check. Perform System Check operation under Manual Mode. *: The exhaust pulsation value is calculated in the ECM. If the calculated value exceeds a certain level, the ECM determines that the exhaust pulsation is in the AIR system. (1) Start the engine and warm it up. (2) Turn the ignition switch off. (3) Connect the Techstream to the DLC3. (4) Turn the ignition switch to ON and turn the Techstream on. (5) Enter the following menus: Powertrain / Engine and ECT / Utility / Air Injection Check / Manual Mode / AIR (6) Start the engine after the Techstream initialization is finished. (7) Perform the AIR system intrusive operation while the engine is idling. (8) Check that the air-fuel ratio and pressure in the secondary air injection system passage (PULSATION) (9) Turn the ignition switch off.
