DTC Advanced Diagnostics: P0630
DTC P0630:VIN Not Programmed or Mismatch

General Description
The DTC P0630 is set before vehicle identification number (VIN) is written and resets after VIN is written. Testing is done by carrying out the VIN write process. This test can be done only after EEPROM first initialization is performed. If the VIN is not registered or incompatible, the PCM detects a malfunction and stores a DTC.
