Multiplexing offers repairers more complete diagnostics
Consequently, multiplexing will modify fault-finding methods
Conventional system
(1) компьютер 1
(2) датчик
The failure of a sensor may result in malfunction of the functions controlled by the ECU 1
Мультиплексная система
(1) компьютер 1
(2) датчик
(3) мультиплексная сеть
(4) компьютер 2
(5) компьютер 3
(6) компьютер 4
The failure of a sensor (controlled by the ECU 1) may result in malfunctions on other functions (controlled by ECUs 2, 3, 4)
It is therefore necessary to retrace the chain of data to find the origin of the fault (сеть, компьютер 1, sensor or wiring)
