VIN Programming Procedure

For more information, please refer to the "IDENTIFICATION NUMBERS " in the Appropriate 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".
