Hi. I have a 2016 Kubota SVL95-2 that is throwing E026 and E027 codes which I understand is no communication with the ECU and ACU controllers. It has a new wiring harness in it due to a small fire starting in the engine bay. There is no voltage on the CAN high and low circuits which I believe to be causing the no communication. I am not able to determine what supplies voltage to the CAN system. I have checked all fuses and connections that I know of. Has anyone ever seen this before? It has me puzzled. Thanks.
No need to worry your heads about this issue. I got a clue from a Kubota guy. The new wiring harness has all new fuses installed but not relays which I never realized and never took the cover off to check. Put relays in and of course the issue went away!
Whew. That tidbit will be mentally filed away for the next time we encounter it.
