Troubleshooting in electronic control systems
requires access to a multimeter and/or PC and
ECOM.
Our electronic control systems store fault
codes in their control units. The fault code can
be read off using a PC and ECOM. It is
generally possible to locate faults and test
various components relatively easily using a
PC and ECOM.
Control Area Network, CAN
Our electronic control systems operate in
networks with other control units and
components, CAN communication.
It is not possible to carry out troubleshooting
with a test lamp in electronic control systems
which use CAN communication. Troubleshooting
is carried out on these control
systems with a PC and ECOM. Cables which
form part of CAN communication controlled
circuits are marked with the letters CAN on
their connections.
