Banks Power Dodge Trucks: (Diesel ’98 - 02 5.9L Cummins ISB) Speed Control- Banks SmartLock (used with CBC-equipped Banks Brake) - Manual (Page 9)

FuNCTioNAL TESTiNg
Once the installation is
complete, a test drive should
be performed to ensure that
the Smartlock Trans Brake
is functioning properly. The
following procedure should be
used to verify that the torque
converter is locked when
the brake is active and that
it disengages at the proper
vehicle speed.
1.
Obtain a steady vehicle
speed in 3rd gear with
overdrive cancelled and the
torque converter locked on a
flat road where it is safe to
allow the vehicle to slow to
approximately 20 mph.
2.
While maintaining this
speed, turn the power switch
for the Banks Brake to the
“ON” position. Release the
accelerator pedal to activate
the exhaust brake and
SmartLock Trans Brake.
3.
Once the exhaust brake is
activated the torque converter
will remain locked and engine
RPM will begin to decrease
at the same rate as vehicle
speed decreases. Allow the
vehicle to slow until the
engine reaches a speed of
approximately 1200 RPM.
At an engine speed of
approximately 1200 RPM, the
Smartlock Trans Brake will
return control of the torque
converter to the factory
computer and it will unlock
causing the engine RPM to
decrease rapidly. This is an
indication that the Smartlock
Trans Brake is functioning
properly.
4.
Obtain a steady vehicle
speed in overdrive with the
torque converter locked on
a flat road where it is safe to
allow the vehicle to slow to
approximately 20 MPH.
5.
While maintaining this
speed, turn the switch for
the Banks Brake to the
“On” position. Release the
accelerator pedal to activate
the exhaust brake.
6.
Once the exhaust brake
is activated, the torque
converter will remain locked
and the engine rpm will begin
to decrease at the same rate
as vehicle speed decreases.
Activate the overdrive cancel
switch and ensure that the
vehicle downshifts to 3rd
gear. Apply light throttle
pressure to allow the torque
converter to re-lock. Release
the accelerator pedal and
ensure that the torque
converter remains locked until
the engine speed drops to
approximately 1200 RPM.
7.
Once this functional
testing is completed, the
Smartlock Trans Brake is
ready for service.
TRouBLE SHooTiNg
If the system fails to function
properly, verify that the wire
taps are installed correctly
and on the proper wires.
If the Smartlock Trans Brake
should ever need to be
removed from the vehicle,
the system includes a by-pass
plug that must be connected
to the white 10-pin connector
in place of the Smartlock
Trans Brake. Failure to utilize
the by-pass plug will result in
a “Check Engine” light on the
dash and a Diagnostic Trouble
Code being stored in the
factory computer.
