5.3.1 Diagnostic Software "Trailer CAN Router-Repeater"

which system – whether CAN Router or -Repeater – is connected and adapts the
display of the diagnostic software accordingly.
The following important tasks are covered by the diagnosis:
Diagnostic memory Under menu point "Messages/Diagnostic memory“, current and aged system errors
and notes are shown (see chapter 6.1 „Diagnostic messages“, page 20).

Status monitoring • Monitoring the CAN communication between the CAN router/repeater and the T-
EBS modulator
If a fault is reported in the CAN communication, the cable connection must be
checked.
If multiple CAN routers are connected in series, each device must be checked
individually. Always choose the interface directly before the CAN router for checking
the communication status to the downstream T-EBS modulator or attached router.
• Monitoring the status of the warning lights
