OPERATING THE BENDIX
EQUIPPED VEHICLE UNDER FAULTED
CONDITIONS
If the Bendix Intellipark
®
system faults while driving, the driver can continue their
route.
If the system has faulted, the capability of the Intellipark
EPB system may be reduced. Drivers must not rely on
the Intellipark EPB system to automatically park the
vehicle. Drivers continue to be responsible for safe
and proper operation of the vehicle.
• Parking with a faulted Intellipark EPB system requires
the following steps to ensure safety:
• Stop on a level surface.
• Shut off the engine and roll down the driver's window
so the exhaust of air from the parking brakes can be
heard.
• Attempt to park the trailer (if able) by pulling the red
switch. Listen for the exhaust of air.
• Attempt to park the tractor by pulling the yellow switch.
Listen for the exhaust of air.
• Fan down the air system until the reservoir pressure is
fully depleted in both primary and secondary circuits.
Confirm the air is fully depleted by checking the dash
gauges or opening the drain cocks on all reservoirs.
• Chock the wheels.
• Remove the vehicle battery power if possible.

It may be necessary to unpark with a faulted Intellipark
®
EPB system. If so, follow these initial steps:
• Leave the wheel chocks in place.
• Apply ignition power if necessary.
• Apply vehicle battery power. Do not start the engine.
• Observe the Dash Electronic Control Unit (DECU)
LEDs.
• With the interlock satisfied, press the yellow switch to
release the parking brakes.
If the Intellipark EPB system is reporting a fault and the
vehicle must be operated, perform the following steps:
• Check dash gauges to ensure the air reservoirs are
fully depleted of air. If not, fan down the reservoirs, if
necessary, by repeatedly applying and releasing the
service brakes to automatically apply the spring brakes
on both the tractor and trailer.
• Once the air reservoirs are depleted of air, remove the
wheel chocks prior to starting the engine.
• Start the engine and stay in the driver's seat as the air
reservoirs charge.
• Use the service brakes to hold the vehicle stationary
in case the spring brakes unintentionally release as
air pressure builds.
In case of emergency, the service brakes can be fanned
down by repeatedly applying and releasing the service
brakes to automatically apply the parking brakes on
both the tractor and trailer.
