Failures in the CAN driver LVC138A (photo 2) – completely eliminated until it was possibleĪll supply voltages of stabilizers – 12v, 5v, 3v, measured in static and in dynamics – there are no drawdowns. RF interference due to poor high-frequency isolation in the power circuit 5 V.ģ. Has drawn a card of voltages of cards ISO and CAN – it will be necessary for the future.Īnalyzed and made sure that the problem is only in the CAN board.Ģ.
I took measurements and looked at the oscilloscope.
Some of the suggestions from Ineta were confirmed by the results of my experiments. Look here: The problem of communication loss Renault Can Clip Alliance VI (926573)
