30106
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.
