VIN Programming Procedure
VIN (Vehicle Identification Number) is a number with the vehicle 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 "IDENTIFICATION NUMBER DESCRIPTION " 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) will be set.
CAUTION:
VIN cannot be changed once it is programmed. Confirm carefully when writing the VIN.
