Code P0630 Honda Description

The Powertrain Control Module (PCM) stores a Vehicle Identification Number (VIN) in the Electrically Erasable Programmable Read-Only Memory (EEPROM) and outputs the VIN according to commands from the Honda Diagnostic System (HDS). The VIN for each vehicle is registered to the PCM using the HDS. The registered VIN is read by the Central Processing Unit (CPU) from the EEPROM after the vehicle is turned to the ON mode or after the Clear command is executed. If the VIN is not registered in the EEPROM 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 Diagnostic Trouble Code (DTC).
