TROUBLESHOOTING
If an existing Six-Gun Tuner has
been previously installed, verify
that the Tuner has the latest
version firmware. Check and
compare to the current version
available on the Banks website.
Banks Brake may not function
properly if Six-Gun Tuner firmware
is not up to the current version.
Six-Gun & Brake Troubleshooting
(Using Tuner/Module LED’s)
If you feel that your Six-Gun Diesel
Tuner and/or Banks Brake is not
functioning properly, some diagnostics
can be performed. Your Six-Gun Diesel
Tuner and Banks Brake is equipped
with diagnostic features that will
detect and display certain errors.
Remove the Six-Gun Diesel Tuner
and Banks Brake from its mounting
location while keeping all connectors
plugged in. Turn the vehicle key to the
ON position. Observe the two LEDs
mounted on the upper corner of the
brake and/or the Six-Gun Diesel Tuner.
• 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
temperature is not within its normal
operating range. The GREEN LED will
stop flashing once the engine coolant
temperature is with normal operating
range. Power will not be added if the
coolant temperature is not within its
normal range.
• None of the LeDs will illuminate if
the fuse on the Six-Gun wiring harness
is blown or the power supply hook-
up is not properly connected. If the
power connection and fuses are okay,
contact Banks Technical Service.
• the ReD LeD will flash if a
connection is incorrect or if there is
a problem with the system, when
the engine is running. The RED LED
will flash in sequence to identify a
particular fault code. A Six-Gun Diesel
Tuner’s fault 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. 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 Six-Gun Tuner fault
codes.
Table 2 lists the Banks Brake fault
codes.
For example, if a faulty thermocouple
is detected (code 2,3) by the Six-
Gun Diesel Tuner, 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 fault code
will be eliminated and replaced with
a steady GREEN LED. 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.
