WARNING: This page is about a different car, the 2004 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
  1. Connect the hand-held tester to the DLC3.
  2. Record the DTCs, freeze frame data and misfire counter data.
  3. Use the hand-held tester to set the check mode (see PRE-CHECK ).
  4. Read the value on the misfire counter for each cylinder while idling the engine. If the value is displayed on the misfire counter, skip step (e).
  5. Drive the vehicle several times with the engine speed, load and its surrounding range shown with ENGINE SPD, CALC LOAD in the freeze frame data or MISFIRE RPM, MISFIRE LOAD in the DATA LIST.

    If you have no hand-held tester, turn the ignition switch OFF after the symptom is simulated once. Then repeat the simulation process again.

    HINT:

    In order to memorize the misfire DTC, it is necessary to drive with MISFIRE RPM, MISFIRE LOAD in the DATA LIST for the period of time in the chart below. Take care not to turn the ignition switch OFF. Turning the ignition switch OFF switches the diagnosis system from check mode to normal mode and all DTCs, freeze frame data and other data are erased.

    ENGINE SPEED TIME

    Engine Speed Time
    Idling 3 minutes 30 seconds or more
    1,000 RPM 3 minutes or more
    2,000 RPM 1 minute 30 seconds or more
    3,000 RPM 1 minute or more
  6. Check if there is misfire or not by monitoring DTC and the freeze frame data. Record the data.
  7. Turn the ignition switch OFF and wait for at least 5 seconds.
