The EC-30

™

 controller ABS function utilizes the following 

components:

-  Wheel speed sensors (4 or 6, depending on 

confi guration)

- 

Electro-pneumatic ABS modulator valves (4)

-  Dash mounted tractor ABS warning lamp (relay 

controlled)

- 

Service brake relay valve

-  Dash mounted trailer ABS warning lamp (towing 

vehicles manufactured after March 1, 2001)

- 

Blink code activation switch (optional)

The EC-30

™

 controller ATC function utilizes the following 

additional components:

- 

ATC modulator - Integral to the ATR (antilock/traction 
relay) valve assembly

- 

Dash mounted ATC active/warning lamp

-  Serial communication to engine control module 

(interfaces with throttle input and engine torque)

- 

ATC enable/disable switch

The EC-30

™

 controller electronics are contained in a non-

metallic housing and are environmentally protected by a 
hard epoxy potting compound.  The design of the EC-30

™

 

controller electronics is robust against radio, electro-
magnetic and environmental interference.

A patented LED (light emitting diode) diagnostic display 
and magnetic reset switch are incorporated in the housing 
for simple, self-contained diagnostics.

The EC-30

™

 controller utilizes a 30-pin and an 18-pin wire 

harness to interface with ABS, ATC and vehicle system 
components.

The EC-30

™

 controller has been designed to replace the 

EC-17

™

 and the EC-16

™

 controllers as the standard Bendix 

ABS controller for OEM and aftermarket installations.  The 
EC-30

™

 controller has a black plastic enclosure similar to 

the EC-17

™

 controller.  However, the EC-30

™

 controller 

utilizes plastic mounting inserts to reduce mounting bolt 
corrosion, where the EC-17

™

 controller utilizes metal 

mounting inserts.  The EC-16

™

 controller utilizes a totally 

metal enclosure.

The EC-30

™

 controller ABS warning lamp power-up 

sequence has been simplifi ed compared to the EC-17

™

 

and EC-16

™

 controllers.

The EC-30

™

 controller ABS warning lamp, at power-up without 

faults, will illuminate for 2.5 seconds and then turn off.

The ABS warning lamp for EC-17

™

 and EC-16

™

 controllers, 

at power-up without faults, will illuminate for approximately 
8 seconds and fl ash twice before turning off.

The EC-30

™

 controller can be bracket mounted to the vehicle 

cab or chassis as a stand alone ECU.  See fi gure 1.

The EC-30

™

 controller can be assembled on one of four 

different valve models.  The controller valve assembly is 
then mounted in place of the standard service brake relay 
valve on the vehicle.    An assembly model designation 
is assigned when the EC-30

™

 controller is mounted on 

an AR (antilock relay) valve or an ATR (antilock/traction 
relay) valve.  See fi gure 2.  Some models include bobtail 
proportioning and/or ATC functions.  See  chart 2.
