Document Type and Number:
Japanese Patent JPH0656981
Kind Code:
B2
Abstract:
PURPOSE:To improve the operability and to reduce the time at trouble-shooting of a faulty locating and at real vehicle debug without incurring cost increase and large-sized node by mounting externally a check device, receiving an input data other than the data subjected to pseudo input via a data transmission line and using a stored data. CONSTITUTION:Jumpers 13, 23, 33, 43, 53 connecting a check device 7 to nodes 1-5 of a multiplex harness system in loop in an automobile and a means switching the nodes 1-5 and the check device 7 and sending a data to a transmission line 6 are provided. Further, the device 7 is provided with a pseudo data setting switch 791 to set only a data desired for pseudo input and a setting confirming LED 792. Then a micrprocessor 74 to receive always the data from the line 6 and storing it is provided and the input data other than the pseudo input are data stored via the line 6. Thus,the operability at real car debug is improved and the time is reduced while troubleshooting the faulty location without large-size node and high cost increase.
