DESCRIPTION
GENERAL
The EC-16
 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-16
 controller can 
be assembled and programmed to provide an optional 
traction control feature. Figure 1 shows the basic EC-16
 
controller confi guration. 
Designed to minimize the potential of brake lock up on all 
wheels during aggressive braking, the EC-16
 controller 
based antilock system provides the vehicle with a high 
degree of stability and steerability during braking. In most 
cases, vehicle stopping distance is also reduced. The 
antilock portion of the EC-16
 controller based system 
minimizes wheel skid during hard or aggressive braking. By 
controlling wheel skid at all wheels on the vehicle, optimum 
steering control and stopping distance is obtained. 
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 
information from the sensors during acceleration, as well 
as braking. The system helps maintain vehicle stability on 
hazardous road surfaces and improves driveability and 
safety. 
There are two versions of the EC-16
 controller. The 
older version, was factory pre-programmed with vehicle 
particulars, such as the number of speed sensors, if the 
traction control feature was enabled and the type of traction 
control (torque limiting, differential braking or both). A part 
number was assigned to the EC-16
 controller which was 
specifi c for the programmed features contained in the unit. 
The newer version contains a self confi guring or learning 
feature that allows the EC-16
 controller to be confi gured 
by the user when installed on the vehicle. Because of this 
feature, all of the new version EC-16
 controllers contain 
all the features and options available and will activate the 
specifi c features required for the vehicle it is installed on. 
The new version EC-16
 controller can be installed on 
vehicles with only antilock or vehicles using the traction 
control feature. The procedure for activating the self
