j1939 communication errors when connecting
Posted: Tue 19. May 2020, 21:36
Hello everybody
I am using PEAK-USB CAN for datalogging J1939 equipment. Quite often when connecting to machine, Either in P-CAN view, Busmaster or Simulink, i am getting canbus connection errors on the machine i am connecting to. This only happens when i am pressing connect, and a second after the trouble codes are gone. I have no errors on CAN network, and logging is working fine afterwards. Does anyone of you have an idea on how to avoid this issue?
The biggest issue with this, is that sometimes a LOT of controllers are reporting CAN communication errors, and then goes to safemode. Then i have to restart engine again and start all over again.
I am using tool in passive mode. Or so i think. Maybe i have overlooked something.Does anyone of you have some inputs to this problem?
Cheers
EDIT:
also i am using the right bitrate and have tested with and without CAN-terminator on PEAK-usb can tool. I have two of these tools and problem persists with both. Problem is only happening the second i press connect, and goes away right away. Sometimes when connecting i can hear the engine changes rpm.
