Installation of Banks Brake Switch
CAUTION: Do not use force
when working on plastic parts.
Permanent damage to the part
might result.
1. The Banks Brake switch will be
installed on the driver’s side of the
instrument panel (IP) next to the
steering column (see Figure 15). If a
Six-Gun Power Level Selector switch
has been install use the secondary
drill location on supplied template and
install the Banks Brake switch next to
the Six-Gun switch. Carefully remove
the IP from the dashboard by slowly
pulling outwards from the dashboard
around the edges of the IP, allowing
the mounting pins to pull free from
their dashboard sockets. Automatic
transmission equipped vehicles will
need to set the parking brake and
move the shift lever down to the
lowest gear to allow clearance for
instrument panel removal.
2. Cut out the supplied template
(see Figure 20 on page 23) and align
the template onto the rear of the IP,
squarely seating it on the top of the IP
mounting pin (see Figure 16).
3. Using a 3⁄ 8” Uni-drill bit, center the
bit onto the 3⁄ 8” drill location on the
template and slowly drill through the
IP. Using a 1⁄ 8” drill bit, center and
drill through the 1⁄ 8” location on the
template. Remove and discard the
template and any plastic shavings.
4. On the front side of the IP, align the
Banks Brake label onto the previously
drilled hole (see Figure 17).
5. Remove the nut and internal tooth
washer from the Banks Brake Switch.
Rotate the shaft counter clockwise
until the shaft stops. Verify the
locating washer tab is inserted into the
#5 position on the switch (see Figure
18).
NOTE: If the washer is in any position
other then the #5, your Speed Brake
will not function properly.
Figure 15
97246 v.3.0
17
Figure 16
Figure 17
18
97246 v.3.0
6. After confirming the locating
washer is in the #5 location, install
the switch through the 3⁄ 8” hole on the
backside of the instrument panel. The
alignment pin should rest in the 1⁄ 8”
hole and with the switch fully rotated
counter clockwise; the shaft’s flat side
should be facing the steering column.
Secure switch with internal tooth
washer and nut. Snug the washer; be
careful not to over torque the nut and
damage the plastic threads.
7. Install the knob onto the shaft
facing the Off Level on the Banks
Brake label. On the knob, snug the two
(2) set screws with the supplied 0.050”
hex key wrench.
9. Reinstall the IP panel, make all
electrical connections that were
disconnected. Secure all loose wiring
under the dash with supplied cable
ties.
WARNING: Take care to keep any
cables away from the pedals
or where they could become
tangled.
10. Reinstall the lower knee panel
back in place with the factory
hardware. Tuck any excess cable
behind it for a clean appearance.
-END, SECTION 2-
8. Route the RJ12 connector
(phone like connector) to the Banks
Brake switch cable connector, and
plug the connectors together.

Section 3
Banks Brake Operation
The Banks Brake has five (5) operating
settings; HIGH, MED (medium), LOW,
OFF and FB (Foot Brake Activation). See
Figure 19.
Figure 19: Banks Brake Selector
Switch Guide
CAUTION: Using the HIGH setting
with a lightly loaded vehicle
will result in VERY aggressive
braking. Become familiar with the
characteristics of the Strength
Settings before encountering
slippery road conditions, including
rain, snow and icy.
Foot Brake Activation
When Foot Brake Activation is selected
the Banks Brake will only activate when
the foot brake is applied. In this setting
the Brake will apply the highest level of
braking force to assist in slowing the
vehicle.
To enable Foot Brake Activation, turn the
Brake selector switch to the Foot Brake
Activation (FB) level. To Disable, turn the
switch to any other desired level.
OFF mode allows the vehicle to behave
as if the Banks Brake is not present.
When the selector switch is turned
to the LOW, MED, or HIGH settings,
the Banks Brake will activate and will
downshift the transmission and adjust
the turbocharger vanes, resulting in a
braking effect that slows your vehicle to
15 mph.
HIGH strength achieves the highest
level of braking force by aggressively
downshifting the transmission and
closing the turbocharger vanes. This
setting is recommended for heavily
loaded vehicles or whenever aggressive
braking is desired.
MED (medium) strength achieves a
moderate level of braking force by
slightly delaying transmission downshifts.
This setting is recommended for
moderately loaded vehicles.
LOW strength setting achieves a
lower level of braking force and is
recommended for lightly loaded or
unloaded vehicles. The LOW setting may
also be used for daily driving.
20
97246 v.3.0
CAUTION: Your Banks Brake is
NOT a substitute for the hydraulic
brakes on your truck. The device
will not correct or compensate for
improperly maintained hydraulic
brakes. Also, please be aware
that your Banks Brake is not
designed to be used as a parking
brake or to bring your vehicle to a
complete stop. Your Banks Brake
is a supplementary braking system
designed to help you slow down or
to assist you in maintaining a more
constant speed when descending a
grade. Remember that Banks Brake
is first and foremost a preemptive
device and is most efficient when
used to help prevent, rather than
correct, a vehicle over speed
situation.
The use of a Banks Brake does not
increase the load capacity of your
vehicle. Gross combined Weight Rating
specifications should always be adhered
to. The Banks Brake will allow you to
slow your vehicle more effectively within
your vehicle’s weight specifications.
Operation/Driving
Now that you are familiar with the
features that are available with Banks
Brake, it is recommended that you
experiment with the various settings
prior to using the braking features in
a towing or extreme driving situation.
Under light load conditions on local
streets, the MED (medium) setting is an
appropriate starting point to provide a
reasonable demonstration that the brake
is functioning.
NOTE: Whenever the brake is active and
the footbrake is applied, the vehicle will
not upshift until the throttle is pressed.
This is also true even if cruise control is
resumed.
For some model vehicles, whenever the
brake is active the vehicles Tow-haul
mode will activate. The tow-haul mode
will deactivate when the Banks Brake is
deactivated.
Wheel Slip Detection
The Banks Speedbrake continuously
monitors wheel speeds to detect
possible slippage caused by braking.
If this occurs, the brake will shut off
until traction is regained and then
remain off for 30 seconds. This will be
communicated as a fault via the Banks
iQ Status Indicator.
-END, SECTION 3-
Section 4
Banks Brake Troubleshooting
If you feel that your Banks Brake is not
functioning properly, some diagnostics
can be performed. Your Banks Brake
module is equipped with diagnostic
features that will detect and display
certain errors.
temperature is not within its normal
operating range. The GREEN LED will
stop flashing once the engine coolant
temperature is within its normal
operating range (not to be confused
with Speed-Loader flash on power-up).
Remove the Banks Brake Module
from its mounting location while
keeping all connectors plugged in,
and position it in such a way that you
can view the end of the Banks Brake
housing that contains the LEDs from
the driver’s seat. Turn the vehicle key
to the ON position. Observe the two
LEDs mounted on the end of the Banks
Brake Module:
• No LEDs will illuminate if the fuse
on the Banks Brake wiring harness
is blown or the wiring harness is not
properly connected. If the fuse and all
connections are okay, contact Banks
Technical Service.
• A steady GREEN LED will illuminate
if all wire connections are correct,
the engine is running, and the engine
coolant temperature is within its
normal operating range.
• The GREEN LED will flash if all wire
connections are correct, the engine
is running, but the engine coolant
• The RED LED will flash in a certain
sequence if a connection is incorrect
of if there is a problem with the
system – this sequence will identify
one or more diagnostic codes. A Banks
Brake diagnostic code is comprised of
2 digits. Each code is expressed in a
sequence of 2 sets of the flashing red
LED separated by a brief flashing of the
green LED in between. Each set of a
number of red LED flashes represents
a digit. A longer flashing of the green

LED separates the sequences. The
LEDs will continue to flash to display
all the errors, and then repeat. Table
1 lists the common diagnostic codes.
For example, if a low relay voltage is
detected (code “2,3”) by the Banks
Brake, the following red and green LED
flashing sequence is observed when
the key is on:
(1) Two times flashing RED LED
(2) One time quick flashing GREEN LED
(3) Three times flashing RED LED
(4) One time longer flashing GREEN LED
The above flashing sequence will
repeat continuously. When the problem
is corrected, the diagnostic code will
be eliminated and replaced by a steady
green light. If problem persists, contact
Banks Technical Service.
NOTE: If multiple codes are set, they
will be displayed in a series separated
by the longer flashing green LED. When
reading codes, make sure to watch
the entire series until you see the first
code repeat.
