Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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 category "GENERAL INFORMATION " in this SERVICE ARTICLE). 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.
- Select "VIN Writing" function in "Vehicle S/W Management".
- Select "Write VIN" in "ID Resister".
- Input the VIN.WARNING: Before inputting the VIN, confirm the VIN again because the programmed VIN cannot be changed.
