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.

PROCEDURE


  1. READ CURRENT DTC


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG) and turn the GTS on.

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

    4. Read the DTCs.

      Note

      If P0630 is set, the VIN must be input to the ECM using the GTS. However, all DTCs are cleared automatically by the tester when inputting the VIN.
