DESCRIPTION
GENERAL
The EC-17
™
is an electronic antilock controller. It is the
base component in a family of full vehicle wheel control
antilock systems for buses, trucks and truck tractors. In
addition to the antilock function, the EC-17
antilock systems for buses, trucks and truck tractors. In
addition to the antilock function, the EC-17
™
controller can
be assembled and programmed to provide an optional
traction control feature. Figure 1 shows the basic EC-17
traction control feature. Figure 1 shows the basic EC-17

Traction control, an optional feature in the full vehicle wheel
control antilock system, helps improve vehicle traction
during acceleration in adverse road conditions. Integrated
with antilock logic, traction control monitors wheel speed

The EC-17
™
controller contains a self configuring or
learning feature that allows it to be con
fi gured by the user
when installed on the vehicle. Because of this feature, all
EC-17
EC-17
™
controllers contain all the features and options
available and will activate the speci
fi c features required
for the vehicle it is installed on. The EC-17
™
controller can
be installed on vehicles with only antilock or vehicles using
the traction control feature. The procedure for activating the

the traction control feature. The procedure for activating the
self con

™
Controller”.
In order to provide full vehicle wheel control antilock, the
EC-17
EC-17
™
controller is used in combination with the following
components:
- Four or six wheel speed sensors
- Four or six wheel speed sensors
- Four air pressure modulator valves
- One dash mounted antilock condition lamp
- One service brake relay valve
