Hi,

Here is face down (LED side) of five microprocessor electronics boards of XS EVOLUTION interfaces.




Two of them, in this case the two electronic boards to the left in the photo above,
have communication problems on CAN bus, and particularly on FULL CAN vehicles.
These two cards out:




The three others, here, do not have this concern:




When you look carefully at the two cards down, one perceives a missing component here:




This is a 10Kohms resistor (marking 103); PULL UP resistor placed on the CAN line that comes
the PIN P94 / TXO microprocessor MB90F546GS and then passes through the logic of HA08 before reaching the optocoupler HCPL 063N!





So if you have CAN communication problems with your interfaces, you can already take a look to see if this resistance is present!
Pending your back ...

Regards.
