Electronic Front Wheel Drive (Fwd) Control - New Holland T8010 Manual

ELECTRONIC FRONT WHEEL DRIVE (FWD) CONTROL

General Description
The FWD consists of the FWD axle, a drive shaft,
FWD clutch, FWD control valve, FWD control switch,
brake pedal switches, true ground speed circuit, hitch
position circuit, transmission speed circuit, and
electronic control modules (through the Data Bus).
Because the FWD is electronically controlled,
automatic operation is possible.
Operating Modes
The FWD system operates in one of three (3) modes
based on operator commands and the signals
received from the other tractor systems.

Section 25 - Four-Wheel Drive Front Axle - Chapter 1
All FWD operator commands are sent to the Arm
Rest Control Module (hard wired to the Arm Rest
Control Module), then relayed to the PTO controller
via the Data Bus. Transmission speed and true
ground speed signals are sent (hard wired) to the
Instrument Cluster Unit (ICU) then relayed to the
PTO controller. Diagnostic and programming
information are communicated between the PTO
controller and the Instrument Cluster Unit (ICU) by
way of the Data Bus.
