TROUBLESHOOTING
If an existing Six-Gun/EconoMind
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/EconoMind
Tuner firmware is not up to the
current version.
Six-Gun/EconoMind/Brake
Troubleshooting
(using Tuner/Module LED’s).
If you feel that your Six-Gun/EconoMind
Diesel Tuner and/or Banks Brake is not
functioning properly, some diagnostics
can be performed. Your Banks Brake/Six-
Gun/EconoMind Diesel Tuner is equipped
with diagnostic features that will detect
and display certain errors. Remove the
Banks Brake/Six-Gun/EconoMind Diesel
Tuner 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 Six-Gun/EconoMind
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 (not to be confused with
Speed-Loader flash on power up).
• None of the LEDs will illuminate if the
fuse on the Six-Gun/EconoMind wiring
harness is blown or the power supply
hook-up is not properly connected. The
power supply wire is the fused wire that
connects to the t-tap at the PcM. 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 Banks Brake/
Six-Gun/EconoMind 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/EconoMind
Tuner fault codes.
Table 2 lists the Brake Module fault
codes.
For example, if a faulty thermocouple
is detected (code 2,3) by the Six-Gun/
EconoMind 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.
