<p>PURPOSE: To provide the multiplex transmitter in which the number of communi cation nodes having an abnormality detection circuit is reduced and the load of a battery power supply is suppressed. CONSTITUTION: A front L node 120 and a front R node 130 are medium and low speed nodes connecting to a medium low speed transmission line MB2, and each node has a data processing CPU 100 and a WD circuit 107' to detect a fault of the CPU 100. Furthermore, output accessories 121 such as a left head light (high beam/low beam), winker lamp are connected to the front L node 120 and output accessories 131 such as a right head light (high beam/low beam), winker lamp are connected to the front R node 120. The front L node 120 and the front R node 130 are integrated into one node and the output accessories 131 having been connected to the font R node 130 is connected to the font L node.</p> |
