The Bendix ® EC-60 ™ controller ATC function utilizes the
following additional components:
• Drive axle traction control valve (may be integral
to the service brake relay valve or a stand-alone
device)
• Dash-mounted ATC status/indicator lamp
• J1939 serial communication to engine control
module
• Stop lamp switch input (may be provided using the
ECU hardware input or J1939)
• Optional ATC mud/snow switch (sometimes referred
to as an ATC off-road switch)
The EC-60 controller Hill Start Feature utilizes the following
additional components:
• Bendix ® AT-3 ™ Traction control valve
• Dash-mounted HSA Status/indicator lamp
• Dash-mounted enable/disable Switch
• Bendix
® RV-3 ™ Pressure reducing valve
• Bendix ® DC-4 ® Double check valve

BENDIx ® ETRAC ™ AUTOMATED AIR
SUSPENSION TRANSFER SYSTEM
The Bendix ® eTrac ™ automated air pressure transfer
system is used on 6 x 2 semi-tractors that feature Bendix ®
premium and advanced Antilock Brake Systems (ABS).
This system complements the Bendix ® Smart Automatic
Traction Control (ATC ™ ) feature of our ABS system to
provide improved traction at low speeds (e.g. pulling away
on an inclined ramp, or in slippery conditions such as mud
or snow-covered surfaces, etc.) When active, the Bendix
eTrac system vents — or “dumps” — the air pressure of
the tag axle suspension air bags, and increases the air
pressure in the drive axle suspension air bags to a pre-
determined maximum. This action helps the drive axle to
gain more traction.
See SD-13-21021 for more information.
ECU MOUNTING
The Bendix ® EC-60 ™ advanced cab-mounted controller is
not protected against moisture, and must be mounted in
an environmentally protected area.
All wire harness connectors must be properly seated. The
use of secondary locks is strongly recommended.
Cab ECUs utilize connectors from the AMP MCP 2.8
product family.
HARDWARE CONFIGURATIONS
Advanced Bendix ® EC-60 ™ controllers support applications
up to six sensor/six modulator (6S/6M) installations with
ATC and drag torque control. They can support HSA
functions. All 12 volt models support PLC. 24 volt models
do not support PLC. See Chart 1 for more details.
