<p><P>PROBLEM TO BE SOLVED: To provide an electronic control unit for configuring a plurality of models by identical circuit boards. <P>SOLUTION: A circuit board 40 comprises an MPU 1 with a program adaptable to a plurality of models and a through-hole for pull-up 41a and a through-hole for pull-down connected to the MPU1 via a resistor 5. A laminated bus bar 30 comprises a power supply terminal 31a guiding a power supply and corresponding to the through-hole 41a and a ground terminal 31b guiding to a ground and corresponding to the through-hole 41b. When the bus bar 30 is coupled with the circuit board 40 in a state that either the power supply terminal 31a or the ground terminal 31b is shortened, the shortened terminal is not contacted with the through-hole corresponding to the shortened terminal but the not-shortened terminal is contacted with the through-hole corresponding to the not-shortened terminal. A model signal according to which terminal is shortened is inputted to the MPU 1. <P>COPYRIGHT: (C)2004,JPO</p> |
