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. For more information, please refer to the IDENTIFICATION NUMBERS . ). 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 Register'.
