You need the latest version of Truck Com for RRE H trucks, older versions wont work correctly with these.

Also certain early IPM's depending on there serial number required replacement & there was a safety campaign to replace them under warranty.

FWIW any NEW electronic component like a CID, IPM, MCU etc will come without the firmware in & require a firmware download then configuration with Truck Com once fitted on to the truck.

I see it's a 200 HCC - there is an active extended warranty campaign for the main over mast hose to the free lift cylinder due to the rubber outer sheath coming of the hose exposing the braiding. Ask your dealer tech to look up BQM 1803.

The factory are currently working on / trialling a upgraded hose.
