MBS-2 Installation

The Wabash National Modular Brake System –2 (MBS-2) is Wabash’s second

generation Trailer Antilock Brake System. All MBS-2 controllers incorporate

the new PLC (power line carrier) data link that permits tractor to trailer

communications. In addition MBS-2 systems incorporate the new Wabash

active wheel speed sensor based on Hall Effect technology. The use of this

new sensor adds several new advantages:

•Mounting the sensor inside the hubcap provides a protected environment

as well as a fixed location for the sensor and magnet. This reduces fleet

maintenance by avoiding excessive gap issues associated with the

traditional VR sensor.

• Ability to detect when the trailer is moving in reverse. The ECM reads the

reverse signal and provides output drives that can be used to light a back

up light or to raise a self steering lift axle.

• Ability to read temperature at the wheel ends. If excessive wheel-end

temperature is detected, the ECM lights a warning lamp and also

transmits a warning signal over the PLC bus.
