VIN Programming Procedure

VIN (Vehicle Identification Number) is a number that has the vehicle's information (Maker, Vehicle Type, Vehicle Line/Series, Body Type, Engine Type, Transmission Type, Model Year, Plant Location and so forth. When replacing an ECM, the VIN must be programmed in the ECM. If there is no VIN in ECM memory, the fault code (DTC P0630) is set.

CAUTIONThe programmed VIN cannot be changed. When writing the VIN, confirm the VIN carefully

  1. Select "Vehicle" and "Engine" (For example, Sedona 3.5L V6).
  2. Select "VIN WRITING".
  3. Check the ECM status. NOTE: VIRGIN: VIN is not programmed LEARNT: VIN has been already programmed Is the ECM status "VIRGIN"? YES Go to step 4 . NO END
  4. Write the VIN with cursor, function and number keys. WARNING: Before pressing the "ENTER" key, confirm the VIN again because the programmed VIN cannot be changed.
  5. After verifying the written VIN, press the "ENTER" key.
  6. Turn the ignition switch OFF, then back ON.
  7. Verify the programmed VIN in the ECM memory.
