DTC P0630:

VIN Not Programmed or Mismatch





General Description

The powertrain control module (PCM) stores a vehicle identification number (VIN) in the keep alive memory (KAM) and outputs the VIN according to the command from the HDS. The VIN for each vehicle is registered to the PCM using the HDS. The registered VIN is read by the CPU from the KAM after the ignition switch is turned to ON (II) or after the Clear command is executed. If the VIN is not registered in the KAM when the ignition switch is turned to ON (II) or when the Clear command is executed, it is detected as a VIN unregistered condition and a DTC is stored.
