MPC10 CAN Bus Failure issue when loaded with PV2.9 config s/w

Hello Everyone,
Greetings..!!

I want to discuss and know the reason for solving the issue of CAN Bus Failure for MPC10 Controller,
while when loaded configuration using PV2.9 version software.
But when the configuration loaded with PV2.8 version software the same issue didn't found.

Issue of CAN Bus Failure was coming as like:-
Engine is running and no faults available and system working,
and when User Press Stop button then Controller state is like, Running Loaded to Cooldown and then to Spindown state.
Within this state time Engine is already stopped and RPM=0.
After this when Spindown state expires, then MPC10 controller gives "CAN Bus Failure" Shutdown.

Please support for this what can be the reason for this kind of Issue.

-regards
