Multiplexing offers repairers more complete diagnostics
Consequently, multiplexing will modify fault-finding methods
Conventional system
(1) калькулятор 1
(2) датчик
The failure of a sensor may result in malfunction of the functions controlled by the ECU 1
Мультиплексная система
(1) калькулятор 1
(2) датчик
(3) мультиплексная сеть
(4) калькулятор 2
(5) калькулятор 3
(6) калькулятор 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, калькулятор 1, sensor or wiring)
