Never found info to calibrate card. Installed new card and handle/housing and solved issue.If you have another unit i would try swapping card between the 2 and see if code changes to the other machine. If it dosent than that will rule out card needing calabration and problem lies somewhere else.

I'm having same fault with a mpv045vg, replaced the tiller control and housing. Can you share the process to calibrate? Thanks

If you could give me the link i would appreciate it. Thank you.

The problem is the tiller card and the wire harness for the tiller card, once a tiller card has been replaced, you need to calibrate, calibrating them is quite a bit of fun, find the process for that then that should solve your issue, if you are unable to find the process I can paste a link if this issue hasn't been solved yet, thanks

The tiller board fails to communicate
with the Combi controller via
CANbus.
Possible causes:
A. CANbus communication error -
no reception of the message via
CAN
B. Error in the tiller board wiring harness
- short circuit or open circuit
on pins 23 and 35 of the Combi
controller.

Carry out a visual inspection of all the connectors paired with the error code.
Restart the truck and check whether the error code is still present.
* Check the wiring harness between the Combi controller (pin 23 and pin 35) and
the tiller board (CRS 18 connector pin 4 and pin 3).
* Check that the connectors are clean.

Thanks that should help. At least point me in right direction. Have new tiller card and upper lower housing along with Steel handle on order.

A. CANBUS COMMUNICATION FAULT
B. TILLER CARD WIRING FAULT
C. FAULTY HANDLE
