Why do I have to fit an additional cable to just one side indicator, even though the indicators on the trailer already work via the CAN bus leads?
It the vehicle is shut down, for example after a breakdown, without an ignition key in position, the CAN bus can go into sleep mode after a while, and so the CAN signal for the indicator is lost. This also acts as a safety feature.
