INSPECTION PROCEDURE

Tech Tips

Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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 ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0630)

    1. Connect the Techstream to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the Techstream on.

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

    5. Read the DTCs.

      Result
      Result Proceed to
      DTC P0630 is output A
      DTC P0630 and other DTCs are output B

      If any DTCs other than P0630 are output, troubleshoot those DTCs first.

      Note

      If P0630 is stored, the VIN must be input to the ECM using the Techstream. However, all DTCs are cleared automatically by the Techstream when the VIN is input. If DTCs other than P0630 are output, troubleshoot them first.
