Serial Communication
The EC-60 ™ controller ESP/RSP function utilizes the
following additional components:
• Steer Axle Traction Control Valve (may be integral
to the service brake relay valve or a stand-alone
device)
• Dash-mounted ESP status/indicator lamp (also
serves as the ATC status/indicator lamp)
• Bendix SAS-60 ™ Steering Angle Sensor (mounted
to the steering column)
• Bendix YAS-60 ™ Yaw Rate/Lateral Acceleration
Sensor (typically mounted to a cross-member near
the back of the vehicle cab)
• Brake Demand Sensors (installed in the primary
and secondary delivery circuits)
• Load Sensor (typically installed in the suspension
air bag)
• An additional Modulator Valve (Bendix ® M-32 ™ or
M-32QR ™ Pressure Modulator Valve) that controls
pressure apply to trailer brakes during system
intervention
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 CONFIGURATION
Advanced model EC-60 ™ controllers support applications
up to six sensor/six modulator (6S/6M) installations with
ATC and drag torque control. Available in 12 volt models,
all advanced model EC-60 ™ controllers support PLC (See
Chart 1).
ADVANCED EC-60 ™ CONTROLLERS USE
POWER LINE CARRIER (PLC)
All new towing vehicles built since March 1, 2001 have had
an in-cab trailer ABS Indicator Lamp installed.
Trailers built since March 1, 2001 transmit the status of
the trailer ABS over the power line (the blue wire of the
J560 connector) to the tractor using a Power Line Carrier
(PLC) signal. See Figures 6 and 7. Typically the signal is
broadcast by the trailer ABS ECU.
The application of PLC technology for the heavy vehicle
industry in North America is known as “PLC4Trucks.”
The Advanced EC-60
™ controller supports PLC
communications in accordance with SAE J2497.
