Hi, having trouble with a Cat Challenger. tried to Flash the Right Hand Module with new flash file and I wasnt paying attention and the challenger technician chose the file and flashed the RHC with the EDC ( electronic draft control ) flash file. Now the RHC cannot communicate, looks like CAN isnt working but module have power etc. Any way to reconnect and reflash the RHC?

It is a Challenger 55 ser: 7DM.
The same as the Claas Challenger series 55.
The same as the New Holland 70 series ( 8970 etc )
and the same as the FaitAgri G series.
Cat used the chassis and gearbox and changed a thing or two.

When starts flashing cut off the battery power. Some times this can help
