what does this error mean 3548 the on-board power supply voltage is too low
i have this error on my car, after many days searching the web, i only found one person who encountered this issue "here on MB world" with no solution for him,
3548 the on-board power supply voltage is too low
normally the car would send an error saying that the battery voltage is too low, what does the "on-board power supply" mean?! where is this power supply?
note: i changed the battery & the ECM/ECU with no luck of resolving this error,
any help would be highly appreciated

on board power supply low means?
I suggest you contact MBZ technical support. They should be able to explain where the 'low voltage' message is being triggered. It can be from a high resistance external connector, the power connector to the particular circuit board, a defective voltage regulator on the circuit board, or many other contributors. Many electronic components are very sensitive to supply voltage and will overheat if voltage is too low.
