INTRODUCTION

Bendix

EC-60

™

controllers are members of a family of electronic

Antilock Braking System (ABS) devices designed to help improve

the braking characteristics of air braked vehicles - including heavy

and medium duty buses, trucks, and tractors. ABS controllers are

also known as Electronic Control Units (ECUs).

Bendix ABS uses wheel speed sensors, ABS modulator valves, and

an ECU to control either four or six wheels of a vehicle. By monitoring

individual wheel turning motion during braking, and adjusting or

pulsing the brake pressure at each wheel, the EC-60

™

controller is

able to optimize slip between the tire and the road surface. When

excessive wheel slip, or wheel lock-up, is detected, the EC-60

™

controller will activate the Pressure Modulator Valves to simulate

a driver pumping the brakes. However, the EC-60

™

controller is

able to pump the brakes on individual wheels (or pairs of wheels),

independently, and with greater speed and accuracy than a driver.

In addition to the ABS function, premium models of the EC-60

™

controller provide an Automatic Traction Control (ATC) feature.

Bendix ATC can improve vehicle traction during acceleration, and

lateral stability while driving through curves. ATC utilizes Engine

Torque Limiting (ETL) where the ECU communicates with the

engine’s controller and/or Differential Braking (DB) where individual

wheel brake applications are used to improve vehicle traction.

Premium EC-60

™

controllers have a drag torque control feature

which reduces driven-axle wheel slip (due to driveline inertia) by

communicating with the engine’s controller and increasing the

engine torque.

Diagnostic Blink Code Switch A momentary switch that grounds the ABS Indicator Lamp output is used to place the ECU into the diagnostic blink code mode and is typically located on the vehicle’s dash panel. ABS Off-Road Switch and Indicator Lamp Operation WARNING: The ABS off-road mode should not be used on normal, paved road surfaces because vehicle stability and steerability may be affected.

Right Steer Right Drive Right Additional Left Drive Left Additional Driver Left Steer FIGURE 8 - VEHICLE ORIENTATION (TYPICAL) ABS OPERATION Bendix ABS uses wheel speed sensors, ABS modulator valves, and an ECU to control either four or six wheels of a vehicle. By monitoring individual wheel turning motion during braking, and adjusting or pulsing the brake pressure at each wheel, the EC-60™ controller is able to optimize slip between the tire and the road surface.
PAGE 7
Normal Braking During normal braking, brake pressure is delivered through the ABS PMV and into the brake chamber. If the ECU does not detect excessive wheel slip, it will not activate ABS control, and the vehicle stops with normal braking. Retarder Brake System Control On surfaces with low traction, application of the retarder can lead to high levels of wheel slip at the drive axle wheels, which can adversely affect vehicle stability.

4. In response to a serial communications request from a diagnostic tool. 5. During brake torque limiting to avoid overheating of the brakes. 6. When certain diagnostic trouble code conditions are detected. Engine Torque Limiting (ETL) with Smart ATC™ Traction Control The EC-60™ controller uses Engine Torque Limiting to control drive axle wheel slip. This is communicated to the engine control module (using J1939), and is available at all vehicle speeds.
PAGE 9
The ABS response sensitivity is reduced when the actual rolling circumference is excessive on all wheels. For a 100 tooth exciter ring, the minimum number of tire revolutions per mile is 426, and the maximum is 567. The ECU will set diagnostic trouble codes if the number of revolutions are out of this range. In addition, the size of the steer axle tires compared to the drive axle tires also has to be within the ABS system design.

Reconfiguring EC-60™ Controllers SYSTEM CONFIGURATION ™ The EC-60 controller is designed to allow the technician to change the default system settings (chosen by the vehicle OEM) to provide additional or customized features. When replacing an ECU, be sure to use an equivalent Bendix replacement part number so that the standard default settings are provided. Depending on the model, the customizable features include ABS control settings, engine module communication etc.

Troubleshooting: General SAFE MAINTENANCE PRACTICES WARNING! PLEASE READ AND FOLLOW THESE INSTRUCTIONS TO AVOID PERSONAL INJURY OR DEATH: When working on or around a vehicle, the following general precautions should be observed at all times: 1. Park the vehicle on a level surface, apply the parking brakes, and always block the wheels. Always wear safety glasses. 2. Stop the engine and remove ignition key when working under or around the vehicle.

Troubleshooting: Blink Codes and Diagnostic Modes ECU DIAGNOSTICS BLINK CODES ™ The EC-60 controller contains self-testing diagnostic circuitry that continuously checks for the normal operation of internal components and circuitry, as well as external ABS components and wiring. Active Diagnostic Trouble Codes When an erroneous system condition is detected, the EC-60™ controller: 1. Illuminates the appropriate indicator lamp(s) and disengages part or all of the ABS and ATC functions. (See page 9.) 2.

mode selected by the technician, a sequence of one or more groups of blinks. Simply record the number of blinks for each sequence and then use the troubleshooting index on page 17 for active or inactive trouble codes and you will be directed to the page that provides troubleshooting information. DIAGNOSTIC MODES NOTE: Diagnostic Modes 1. Sequences of blinks illuminate the ABS indicator lamp for half a second, with half-second pauses between them. To enter the various diagnostic modes: 2.
PAGE 14
Using blink codes, the technician may review all inactive trouble codes stored on the ECU. The ABS indicator lamp will display inactive diagnostic blink codes when the diagnostic blink code switch is depressed and released two times. See page 17 for the index showing trouble codes and the troubleshooting guide page to read for help. Inactive trouble codes, and event history, may be retrieved and cleared by using a hand-held or PC-based diagnostic tool, such as the Bendix® ACom™ Diagnostics software.
