P0630

Ignition switch ON

CAUTION / NOTICE / HINT

Tip:

Read freeze frame data using the GTS. 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, and other data from the time the malfunction occurred.

PROCEDURE

  1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0630)

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS ON.

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

    4. Read the DTCs.

      Powertrain > Engine and ECT > Trouble Codes

      Note:

      If P0630 is output, the VIN or frame number must be written to the ECM using the GTS. However, all DTCs are cleared automatically by the GTS when the VIN or frame number is written. If DTCs other than P0630 are output, troubleshoot them first.
