J1939 page
Your vehicle is equipped with 2 different CAN-based communication buses:
the J1939 bus, which is used for the chassis equipment; and
the CANopen bus, which is used for the body.
These 2 communication buses are completely independent of one another, except for some specific
data that are transferred from the chassis J1939 bus to the IFM Multiplex System, where they are
used. These specific data are the following:
selected gear
current gear
road speed
engine rpm
brake
parking brake
