DESCRIPTION
GENERAL
Bendix antilock systems utilizing the EC-15
 electronic 
controller assembly provide full vehicle, wheel control 
braking for buses, trucks, and truck tractors. By minimizing 
the potential of “brake lock-up” on all wheels during 
aggressive braking the vehicle retains a high degree of 
stability and steerability, and in most cases vehicle stopping 
distance is reduced.
In order to provide full vehicle, wheel control braking, the 
EC-15
 controller assembly is used in combination with 
the following components:
- Four, individual wheel speed sensors
- Four, air pressure modulator valves
- Antilock condition lamp (dash mounted)
PHYSICAL
The EC-15
 controller electronics, that regulate the function 
of the antilock system, are contained in a die cast aluminum 
housing and are environmentally protected. The metal 
housing, coupled with the design of the digital electronics, 
is intended to provide a high degree of protection from 
radio and electromagnetic interference.
A diagnostics display window with 9 light emitting diodes 
(LEDs) and a magnetically actuated reset switch is 
incorporated in the housing for troubleshooting and 
diagnostic purposes.
Two types of electrical connectors are currently used to 
connect the EC-15
 controller assembly to the antilock 
system components; a single, 30 pin, Packard Electric, 
150 series “Metri-pack” or a pair of 14 pin, Deutsch, HID 
30 series connectors.
