DTC P0630
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 commands 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 vehicle is turned to the ON mode, or after the Clear command is executed. If the VIN is not registered in the KAM when the vehicle is turned to the ON mode, or when the Clear command is executed, the PCM detects a VIN unregistered condition and stores a DTC.
