ABSTRACT:
A data processing apparatus for a vehicle which permits accurate and reliable registration of a key ID code in a vehicle. ID code detecting means detects an ID code received in succession from outside. The ID code detected previously is registered in the memory 132 for previous ID code; the ID code detected this time is registered in the memory 133 for the present ID code. First comparing means compares the previous ID code with the present ID code and if the two ID codes match, then the ID code is registered as a reference ID code in an EEPROM. Second comparing means compares the present ID code with the reference ID code and if the two ID codes match, then it issues an engine control enable (OK) signal to an engine CPU.
