Ducati Hyper821 - ECU Magneti Marrelli - CAN LINE error

[lengtrung]

Hi guys, I'm Trung, from Vietnam,
my bike got a serious problem - CAN LINE error, hope you will support me to fix this issue.

One month ago, I got the error "CAN LINE" on dashboard, all light flashing, fan turns on, push start button but not working, the bike totally dead ! Then I open the dash, I see the IC CAN Transceiver "TJA1040", I had replaced it, the bike lives again, everything works perfectly!
Now I get the same problem, I thought cause IC CAN, I replaced it but the bike still dead ! I use multimeter to measure the CAN bus (without battery), each node the same 59.2ohm, the resistor is fine!
The dashboard shows :
+ DTC ( Ducati Traction Control): "---"
+ ABS : "---"
+ RPM bar : flashing
+ Engine temperature : "---"
+ Speedometer : "---"
+ All light flashing

BUT : when I unplugging the ECU,
+ ABS : "2"( 2nd mode ABS)
+ speedometer : "0 km/h"

So I think my ECU got the fault, but I don't know what is the fault ! Thank you for your help will appreciate.

PS: When I unplugging the fuse of ECU then re-plugging it, the dashboard seems received signal CANbus in 1 second ( DTC, ABS, engine temperature) then everything fault again. So my idea maybe the power of ECU fault , IC driver control fuel pump fault, etc...

My ECU uses st10f296 chip
