A programmed microprocessor has a learning mode of operation wherein data to and from a circuit coupled to a wiring harness in a vehicle is stored by the microprocessor. After the learning mode is completed, removal of the circuit does not cause an error condition because appropriate data is supplied instead by the microprocessor. A sleep mode of operation prevents the microprocessor from interfering with the operation of the circuit when the circuit and the microprocessor are coupled to the wiring harness.
