BENDIX SD-13-4869 User Manual

Advanced ECU can include Yaw Control (YC) functionality, 

which has the ability to apply brakes to individual wheel 

ends, as well as applying the trailer brakes, to counteract 

trailer “push” that, during certain maneuvers, could lead to 

a loss-of-control or a jackknife incident.  See "Yaw Stability" 

on page 9 for further details.

The Bendix Roll Stability Program (RSP), is an all-axle 

ABS solution that helps reduce vehicle speed by reducing 

the engine's throttle and applying all vehicle brakes as 

needed, reducing the vehicle's tendency to roll over.  RSP 

focuses on reducing the vehicle’s speed below the critical 

roll threshold during direction-changing maneuvers such as 

driving on curved highway exit ramps or obstacle avoidance 

maneuvers on dry, high friction surfaces.  See "Advanced 

ABS with Stability Control" on page 12 for further details.

During an RSP system intervention, the vehicle 

automatically decelerates .  RSP can slow the vehicle 

with or 

without the operator applying the brake pedal, 

and 

The Bendix EC-60 controller’s ABS function utilizes the 

following components:

• Bendix

®

 WS-24

™

 wheel speed sensors (4 or 6, 

depending on configuration).  Each sensor is 

installed with a Bendix Sensor Clamping Sleeve

• Bendix

 M-32

™

 or M-32QR

 Pressure Modulator 

Valves (4, 5, or 6 depending on configuration)

•  Dash-mounted tractor ABS Indicator Lamp
•  Service brake relay valve
•  Dash-mounted trailer ABS Indicator Lamp
•  Optional blink code activation switch
•  Optional ABS off-road switch

The Bendix 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 - See Figure 4)

: When replacing a steering wheel, 

take care not to damage the Steering Angle Sensor 

or interfere with its operation, and the Steering Angle 

Sensor must be recalibrated (see Troubleshooting
