i WABCO Maintenance Manual MM-1719 (Revised 08-18)

ASBESTOS FIBERS WARNING The following procedures for servicing brakes are recommended to reduce exposure to asbestos fiber dust, a cancer and lung disease hazard. Material Safety Data Sheets are available from WABCO.

Hazard SummaryBecause some brake linings contain asbestos, workers who service brakes must understand the potential hazards of asbestos and precautions for reducing risks. Exposure to airborne asbestos dust can cause serious and possibly fatal diseases, including asbestosis (a chronic lung disease) and cancer, principally lung cancer and mesothelioma (a cancer of the lining of the chest or abdominal cavities). Some studies show that the risk of lung cancer among persons who smoke and who are exposed to asbestos is much greater than the risk for non-smokers. Symptoms of these diseases may not become apparent for 15, 20 or more years after the first exposure to asbestos.

Accordingly, workers must use caution to avoid creating and breathing dust when servicing brakes. Specific recommended work practices for reducing exposure to asbestos dust follow. Consult your employer for more details.

Recommended Work Practices1. Separate Work Areas. Whenever feasible, service brakes in a separate area away from other operations to reduce risks to unprotected persons. OSHA has set a maximum allowable level of exposure for asbestos of 0.1 f/cc as an 8-hour time-weighted average and 1.0 f/cc averaged over a 30-minute period. Scientists disagree, however, to what extent adherence to the maximum allowable exposure levels will eliminate the risk of disease that can result from inhaling asbestos dust. OSHA requires that the following sign be posted at the entrance to areas where exposures exceed either of the maximum allowable levels:

DANGER: ASBESTOSCANCER AND LUNG DISEASE HAZARD

AUTHORIZED PERSONNEL ONLYRESPIRATORS AND PROTECTIVE CLOTHING

ARE REQUIRED IN THIS AREA. 2. Respiratory Protection. Wear a respirator equipped with a high-efficiency (HEPA) filter approved by NIOSH or MSHA for use with asbestos at all times when servicing brakes, beginning with the removal of the wheels.3. Procedures for Servicing Brakes.a. Enclose the brake assembly within a negative pressure enclosure. The enclosure should be

equipped with a HEPA vacuum and worker arm sleeves. With the enclosure in place, use the HEPA vacuum to loosen and vacuum residue from the brake parts.

b. As an alternative procedure, use a catch basin with water and a biodegradable, non-phosphate, water-based detergent to wash the brake drum or rotor and other brake parts. The solution should be applied with low pressure to prevent dust from becoming airborne. Allow the solution to flow between the brake drum and the brake support or the brake rotor and caliper. The wheel hub and brake assembly components should be thoroughly wetted to suppress dust before the brake shoes or brake pads are removed. Wipe the brake parts clean with a cloth.

c. If an enclosed vacuum system or brake washing equipment is not available, employers may adopt their own written procedures for servicing brakes, provided that the exposure levels associated with the employer’s procedures do not exceed the levels associated with the enclosed vacuum system or brake washing equipment. Consult OSHA regulations for more details.

d. Wear a respirator equipped with a HEPA filter approved by NIOSH or MSHA for use with asbestos when grinding or machining brake linings. In addition, do such work in an area with a local exhaust ventilation system equipped with a HEPA filter.

e. NEVER use compressed air by itself, dry brushing, or a vacuum not equipped with a HEPA filter when cleaning brake parts or assemblies. NEVER use carcinogenic solvents, flammable solvents, or solvents that can damage brake components as wetting agents.

4. Cleaning Work Areas. Clean work areas with a vacuum equipped with a HEPA filter or by wet wiping. NEVER use compressed air or dry sweeping to clean work areas. When you empty vacuum cleaners and handle used rags, wear a respirator equipped with a HEPA filter approved by NIOSH or MSHA for use with asbestos. When you replace a HEPA filter, wet the filter with a fine mist of water and dispose of the used filter with care.5. Worker Clean-Up. After servicing brakes, wash your hands before you eat, drink or smoke. Shower after work. Do not wear work clothes home. Use a vacuum equipped with a HEPA filter to vacuum work clothes after they are worn. Launder them separately. Do not shake or use compressed air to remove dust from work clothes.6. Waste Disposal. Dispose of discarded linings, used rags, cloths and HEPA filters with care, such as in sealed plastic bags. Consult applicable EPA, state and local regulations on waste disposal.

Regulatory GuidanceReferences to OSHA, NIOSH, MSHA, and EPA, which are regulatory agencies in the United States, are made to provide further guidance to employers and workers employed within the United States. Employers and workers employed outside of the United States should consult the regulations that apply to them for further guidance.

NON-ASBESTOS FIBERS WARNING The following procedures for servicing brakes are recommended to reduce exposure to non-asbestos fiber dust, a cancer and lung disease hazard. Material Safety Data Sheets are available from WABCO.

Hazard SummaryMost recently manufactured brake linings do not contain asbestos fibers. These brake linings may contain one or more of a variety of ingredients, including glass fibers, mineral wool, aramid fibers, ceramic fibers and silica that can present health risks if inhaled. Scientists disagree on the extent of the risks from exposure to these substances. Nonetheless, exposure to silica dust can cause silicosis, a non-cancerous lung disease. Silicosis gradually reduces lung capacity and efficiency and can result in serious breathing difficulty. Some scientists believe other types of non-asbestos fibers, when inhaled, can cause similar diseases of the lung. In addition, silica dust and ceramic fiber dust are known to the State of California to cause lung cancer. U.S. and international agencies have also determined that dust from mineral wool, ceramic fibers and silica are potential causes of cancer.

Accordingly, workers must use caution to avoid creating and breathing dust when servicing brakes. Specific recommended work practices for reducing exposure to non-asbestos dust follow. Consult your employer for more details.

Recommended Work Practices1. Separate Work Areas. Whenever feasible, service brakes in a separate area away from other operations to reduce risks to unprotected persons.

2. Respiratory Protection. OSHA has set a maximum allowable level of exposure for silica of 0.1 mg/m3 as an 8-hour time-weighted average. Some manufacturers of non-asbestos brake linings recommend that exposures to other ingredients found in non-asbestos brake linings be kept below 1.0 f/cc as an 8-hour time-weighted average. Scientists disagree, however, to what extent adherence to these maximum allowable exposure levels will eliminate the risk of disease that can result from inhaling non-asbestos dust.

Therefore, wear respiratory protection at all times during brake servicing, beginning with the removal of the wheels. Wear a respirator equipped with a high-efficiency (HEPA) filter approved by NIOSH or MSHA, if the exposure levels may exceed OSHA or manufacturers’ recommended maximum levels. Even when exposures are expected to be within the maximum allowable levels, wearing such a respirator at all times during brake servicing will help minimize exposure.

3. Procedures for Servicing Brakes.

a. Enclose the brake assembly within a negative pressure enclosure. The enclosure should be equipped with a HEPA vacuum and worker arm sleeves. With the enclosure in place, use the HEPA vacuum to loosen and vacuum residue from the brake parts.

b. As an alternative procedure, use a catch basin with water and a biodegradable, non-phosphate, water-based detergent to wash the brake drum or rotor and other brake parts. The solution should be applied with low pressure to prevent dust from becoming airborne. Allow the solution to flow between the brake drum and the brake support or the brake rotor and caliper. The wheel hub and brake assembly components should be thoroughly wetted to suppress dust before the brake shoes or brake pads are removed. Wipe the brake parts clean with a cloth.

c. If an enclosed vacuum system or brake washing equipment is not available, carefully clean the brake parts in the open air. Wet the parts with a solution applied with a pump-spray bottle that creates a fine mist. Use a solution containing water, and, if available, a biodegradable, non-phosphate, water-based detergent. The wheel hub and brake assembly components should be thoroughly wetted to suppress dust before the brake shoes or brake pads are removed. Wipe the brake parts clean with a cloth.

d. Wear a respirator equipped with a HEPA filter approved by NIOSH or MSHA when grinding or machining brake linings. In addition, do such work in an area with a local exhaust ventilation system equipped with a HEPA filter.

e. NEVER use compressed air by itself, dry brushing, or a vacuum not equipped with a HEPA filter when cleaning brake parts or assemblies. NEVER use carcinogenic solvents, flammable solvents, or solvents that can damage brake components as wetting agents.

4. Cleaning Work Areas. Clean work areas with a vacuum equipped with a HEPA filter or by wet wiping. NEVER use compressed air or dry sweeping to clean work areas. When you empty vacuum cleaners and handle used rags, wear a respirator equipped with a HEPA filter approved by NIOSH or MSHA, to minimize exposure. When you replace a HEPA filter, wet the filter with a fine mist of water and dispose of the used filter with care.

5. Worker Clean-Up. After servicing brakes, wash your hands before you eat, drink or smoke. Shower after work. Do not wear work clothes home. Use a vacuum equipped with a HEPA filter to vacuum work clothes after they are worn. Launder them separately. Do not shake or use compressed air to remove dust from work clothes.

6. Waste Disposal. Dispose of discarded linings, used rags, cloths and HEPA filters with care, such as in sealed plastic bags. Consult applicable EPA, state and local regulations on waste disposal.

Regulatory GuidanceReferences to OSHA, NIOSH, MSHA, and EPA, which are regulatory agencies in the United States, are made to provide further guidance to employers and workers employed within the United States. Employers and workers employed outside of the United States should consult the regulations that apply to them for further guidance.

1WABCO Maintenance Manual MM-1719 (Revised 08-18)

1 IntroductionContentsThis manual contains service information for the following systems.

� WABCO mBSPTM anti-lock braking system (ABS)

� Automatic traction control (ATC)

� Electronic stability control (ESC) for trucks, tractors and buses

The ABS version is marked on the ECU. Figure 1.1. If you cannot identify the ECU version installed on your vehicle, contact WABCO North America Customer Care at 855-228-3203.

Figure 1.1

Anti-Lock Braking System (ABS)ABS is a system designed to provide and maintain the best possible traction and steering control during an extreme braking event. During a potential wheel lock event, the ABS ECU, using information provided by the wheel speed sensors, sends a signal(s) to the appropriate modulator valve(s) to hold, apply or release the brakes as needed. ABS works automatically. The driver does not have to select this feature.

System Components

Electronic Control Unit (ECU)The ECU is the control center or “brain” of the ABS, ATC and ESC systems. It receives information from the sensors and CAN data link, processes data and sends signals to modulators and active braking valves to achieve different tasks.

Wheel Speed Sensing SystemsWheel speed sensing systems consist of a tooth wheel mounted on the hub or rotor of each monitored wheel and a speed sensor installed with its end against the tooth wheel. The sensor continuously sends wheel speed information to the ECU. A sensor clip holds the sensor in place and against the tooth wheel. Figure 1.2.

Figure 1.2

Pressure Modulator ValvesA modulator valve controls air pressure to an affected wheel-end brake during an ABS or ESC event to reduce speed and prevent wheel lock-up. Modulator valves are also used during ATC events to correctly gain traction on the affected wheel end.

A modulator valve is usually located on a frame rail or cross member near the brake chamber or as part of a valve package. A valve package combines two modulator valves, a service relay or quick release valve, and depending on the vehicle configuration, an active braking valve (ABV). Figure 1.3, Figure 1.4, Figure 1.5 and Figure 1.6.

1 Introduction


Foot Brake Valve (FBV)The foot brake valve (FBV) is part of the mBSPTM brake system. It provides the system with the driver’s brake demand. The FBV generates the electrical and pneumatic signals required for the control of a pneumatic braking system. Normally, the FBV is actuated by a foot pedal assembly. Figure 1.7.

Figure 1.7

Steering Angle Sensor (SAS)The SAS is part of the mBSPTM ESC system. The SAS delivers the driver’s steering input (steering wheel position) to the ECU using the vehicle chassis CAN communication data link. The SAS is provided by the vehicle manufacturer.

Electronic Stability Control (ESC) ModuleThe ESC module is part of the mBSPTM ESC system. It measures the vehicle yaw rate as well as vehicle lateral acceleration. It exchanges data with the ECU via the ESC system internal data link. The ECU supplies the module with voltage and ground. The ESC module must be initialized by diagnostic tools whenever the ECU or the ESC module is replaced. Figure 1.8.

Figure 1.8

Trailer Modulator ValveFor some stability control applications, an additional modulator valve (the same as what is used for ABS modulation) will be located in the trailer control line downstream of the front axle ABV which is also used to control the trailer.

Off-Road ABS SwitchOn some vehicles, an off-road ABS switch can be included. The off-road ABS function improves vehicle control and helps reduce stopping distances in off-road conditions or on poor traction surfaces such as loose gravel, sand and dirt.

ATC SwitchA vehicle manufacturer might offer an ATC switch to control the ATC function. The ATC switch can be configured to momentarily disable ATC.

2 Stability and Safety Enhancement Systems


2 Stability and Safety Enhancement SystemsAutomatic Traction Control (ATC)ATC is available as an option with mBSPTM ECUs and is standard on most. ATC helps improve traction in low traction road conditions. ATC reduces the potential of jackknifing caused by excessive wheel spin during acceleration or in curves.

ATC ComponentsATC uses the base ABS components plus an active braking valve that can be installed with individual modulator valves, or installed as part of the rear valve package.

When installed with individual modulator valves, the active braking valve is mounted on the frame or cross member, near the rear of the vehicle.

When it is part of the rear valve package, the active braking valve is attached to the relay valve.

ATC SwitchIf the vehicle manufacturer offers an ATC switch to control the ATC functionality, the switch can be configured as an ATC momentary override option. This function allows the driver to momentarily disable/override ATC for the duration of the ignition cycle.

Electronic Stability Control (ESC)Electronic Stability Control (ESC) combines the rollover prevention with directional stability in order to keep the vehicle traveling on its intended path by providing spinout and drift out control. ESC is automatic. It becomes active when the system senses imminent directional or roll instabilities, often before the driver is aware. You will notice a difference in the vehicle when stability control is functioning, but you should continue to drive as normal and provide any additional needed corrections. You may again notice a reduction in engine torque and additional deceleration from the retarder, if so equipped. You also may notice individual or all brakes applying depending on whether the vehicle is in a roll or directional control event.

ESC ComponentsESC is built from the ABS platform and uses many of the same components as ATC. An active braking valve to control the front axle brakes and trailer, a foot brake valve, an ESC module and a Steering Angle Sensor (SAS) are required.

The ESC ECU contains parameter settings which are specific to a vehicle configuration validated by WABCO Engineering. It is imperative that the correct ECU is installed on your vehicle in service. Contact WABCO or your respective vehicle OEM with any questions regarding ESC ECU.

Hill Start Aid (HSA)HSA supports select automated manual transmissions in reducing/totally eliminating the rolling back of the vehicle while launching on a grade. When requested from the transmission, HSA holds pressure in the service brakes of all axles of the towing vehicle when the vehicle is standing still. HSA will hold pressure for a maximum of three seconds following full release of the brake pedal.

HSA ComponentsHSA is available with the mBSPTM brake system. Same as ESC, HSA is built from the ABS platform and uses many of the same components as ATC and ESC. HSA uses the front axle active braking valve as well as the rear active braking valve to help maintain the pressure trapped during HSA activation.

The foot brake valve provides the system with the driver’s brake demand. The measured pressure is used by HSA to set the trapped pressure and/or activate the HSA function. The vehicle manufacturer can provide an HSA switch multiplexed through the dashboard or hard wired for momentary HSA deactivation.

Drag Torque ControlThe ABS ECU has the ability to send a message to the engine to increase engine RPM to prevent drive axle lock-up, if the vehicle is on a downhill grade and in the incorrect gear.

3 Diagnostics, Troubleshooting and Testing


3 Diagnostics, Troubleshooting and TestingMaintenance InformationThere is no regularly scheduled maintenance required for the WABCO mBSPTM ABS, ATC or ESC systems. However, this does not change current vehicle maintenance requirements.

� Lamp Check: To ensure the ABS tractor lamp is operating, drivers should check the lamp every time the vehicle is started. When the vehicle is started, the ABS lamp should come on momentarily. If it does not come on, it could mean a burned-out bulb.

� ABS Wheel Speed Sensors: Check the wheel speed sensor adjustment and lubricate the sensor and sensor clip whenever wheel-end maintenance is performed. Use only WABCO- recommended lubricant.

ABV Testing

Electrical Checks

� Check ABV 3/2 solenoid by itself for resistance.

� Check ECU harness and ABV 3/2 solenoid together for resistance. Figure 3.7.

� Verify no change in resistance or open circuit between ABV by itself and through harness.



ESC CAN Network TestingThe ECU and ESC module are all connected on propriety CAN network with internal terminating resistors on each one of these components. A failure to one of the components will cause others to fault out.

ESC Module Testing

Electrical Checks

For the following checks, all of the ECU connectors must be plugged in. The ECU provides voltage, ground and CAN communication to ESC module.

� Take measurements at the ESC module harness connector.

� Measure voltage supply Key ON.

� Measure CAN High voltage Key ON.

� Measure CAN Low voltage Key ON.

� Measure terminating resistance across CAN High and Low with Key OFF.

With ECU and ESC Module disconnected:

� Verify continuity end to end on each line

� Verify no shorts to ground or battery on all lines.

� Verify no continuity between pins.

Measurements should read as follows:

ESC Module MountingThe ESC module contains sensors which measure both lateral acceleration and yaw rate. Thus, it is critical that the module is securely mounted, leveled and in correct location to the vehicle and that the module is mounted as expected by the ECU and as per vehicle OEM specifications.

The module should be installed in a manner where the label is right side up. The module must be mounted perpendicular to the vehicle frame rails on a cross member or cross member bracket. The module connector could be facing the front or rear of the vehicle depending on the OEM’s specified mounting. It is critical that the unit be mounted in the exact location and manner as originally installed by the vehicle manufacturer.

SAS TestingContact the OEM for electrical checks and all troubleshooting.
