| The new Wabash National MBS-2® brake system forms the basis
for the Smart Trailer suite. This next-generation ABS system
stands alone with industry-leading innovative design.
FULL COMMUNICATION WITH TRACTOR
The MBS-2® control module communicates with the tractor via
the industry-standard PLC4TRUCKS protocol. ABS warning light in
the cab is automatically controlled by the MBS-2® module.

INTELLIGENT MBS-2® MODULE STORES CRITICAL TRAILER DATA ELECTRONICALLY
Important information such as VIN, Unit Number, and current trailer
mileage, are store din the MBS-2® module, available for easy
access. Soon, additional data such as a complete listing of the
trailer's parts will be added.
NEW ACTIVE SPEED SENSOR IN HUB
A maintenance breakthrough! New design speed sensor eliminates troublesome
tone rings. No more ABS malfunction due to the sensor backing out
of its mount and losing contact with the tone ring, the most frequent
cause of ABS failure. The sensor is contained in a controlled environment,
yet is easily accessible through the hubcap.
ELECTRIC ODOMETER STANDARD
MBS-2® tracks tire revolutions, providing highly accurate mileage
data for maintenance, tracking purposes.
Optional Features:
An exciting array of new Smart Trailer features are available as
options, supported by the MBS-2® brake system. These features
offer major advances in motor carrier safety and efficiency.
TRAILER BACK-UP LIGHT & WARNING HORN SYSTEM
Automatically actuated by rearward rotation of the trailer wheels,
the automatic backup light provides bright illumination to the trailer
rear, greatly easing the driver's task at night and alerting bystander
to the backing trailer. Automatic backup horn provides an audio
alert, providing an additional factor of safety. Backup lights/horn
are available as a package or separately.
OVERHEATED WHEEL END DETECTION SYSTEM
Monitors bearing temperature on all wheels (4S/1M MBS-2® system
recommended for all dual axle trailers). Automatically alerts driver
of an overheating bearing through Trailer Mounted Status Light or
to tractor display via PLC4TRUCKS communication. Provides warning
of unsafe condition before catastrophic failure occurs.
TRAILER MOUNTED STATUS LIGHT
Easily visible in the driver's rearview mirror, the trailer mounted
status light provides continuous feedback to the drive on trailer
status:
Green - All Systems OK
Yellow - Minor Trailer Fault
(ABS Malfunction)
Red - Major Fault, Stop Immediately!
(Overheated Wheel End)
Also functions as a maintenance display with blink code output for
easy trailer diagnostics.
