NOTE: The following testing should be
performed only after the vehicle has
been allowed to COMPLETELY COOL.
This test verifies the performance of
the warm-up feature of the brake
system and must be performed with
a cold vehicle.
77.
Verify that the Banks Brake
Activation Switch is in the “OFF”
position.
78.
Ensure that the accelerator
pedal is NOT depressed. Turn the
ignition key to the “ON” position. The
green LED on the Computerized Brake
Controller (CBC) should light up and
the air compressor should run for
approximately 2 seconds before
turning off.
79.
Slowly press the accelerator
pedal. The green LED should turn off
almost immediately (very little
throttle movement) and the air
compressor panel should vent the
air from the brake actuator. Release
the accelerator pedal and the green
LED should again light up and the
compressor should run for
approximately 2 seconds and then
shut off. Repeat this cycle a few
times to verify CBC function.
80.
Start the engine and let it idle.
The brake valve will close and can be
verified by the muffled sound of a
restricted exhaust pipe.
81.
Slowly press the accelerator
pedal The green LED should turn off
almost immediately (very little
throttle movement) and the air
compressor panel should vent the air
from the brake actuator and the
brake valve should open. Release the
accelerator pedal and the green LED
should again light up and the
compressor should run for
approximately 2 seconds and then
shut off. Repeat this cycle a few
times to verify CBC function. NOTE:
The engine speed (RPM) should not
exceed 1200 rpm prior to brake
disengagement.
82.
Allow the vehicle to reach
normal operating temperature. The
brake will remain active until the
vehicle reaches approximately 125°F
engine coolant temperature
(measured with a Tech II scan tool).
Once the vehicle warms
up, the brake will turn off.
83.
Re-install the lower dash panel.
NOTE: Once the vehicle has passed
the initial functional tests outlined in
Steps 77-82 the vehicle can be
driven in order to complete the
required functional testing.
84.
Obtain a vehicle speed of
approximately 40-45 mph in an area
where speeds of this nature are safe
and traffic is light. Turn the Banks
Brake activation switch to the “ON”
position. Release the throttle. The
brake should activate and the vehicle
will begin to slow. Bring the vehicle
to a safe stop (using the service
brakes). As the vehicle speed drops
below approximately 15 mph the
brake should turn off. Turn the Banks
Brake activation switch to the “OFF”
position
85.
Obtain a vehicle speed of
approximately 40 mph in an area
where speeds of this nature are safe
and traffic is light. Set the cruise
control to 40 mph. Activate the Banks
Brake by placing the activation
switch in the “ON” position. The
cruise control should disengage and
the vehicle should begin to slow.
86.
