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. For more information, please refer to the group GENERAL INFORMATION in this SERVICE INFORMATION). 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.

CAUTION: The programmed VIN cannot be changed. When writing the VIN, confirm the VIN carefully.
  1. Select "VIN Writing" function in "Vehicle S/W Management".
  2. Select "Write VIN" in "ID Resister".
