Six-Gun Troubleshooting
(No Banks PowerPDA Installed)
Your Six-Gun Diesel Tuner is equipped
with diagnostic features that will
detect and display certain errors.
Remove the Six- Gun 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 end of the Six-Gun
Diesel Tuner, next to the harnesses.
If all wire connections are correct, a
steady GREEN LED is illuminated. If the
GREEN LED is not illuminated when
the ignition is ON, check power supply
hookup and the fuse on the Six-Gun
main wire harness. If the connections
and fuse are okay, contact Banks
Technical Service.
If a connection is incorrect or if
there is a problem with the system,
when the ignition is ON the RED LED
will flash in sequence to identify a
diagnostic code. A Six-Gun Diesel
Tuner’s 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 available diagnostic codes
and the recommended course of
action for each. 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
ignition 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
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.
NOTE: The “4,3” code comes on when
the Six-Gun Diesel Tuner module is
first installed on a vehicle. To eliminate
this code, follow the instructions
described in “Transmission Learning”
(Section 6). If problem persists,
contact Banks Technical Service.
If the Six-Gun Diesel Tuner should ever
need to be removed from the vehicle,
all vehicle connectors must be re-
connected to their stock configuration.
Failure to reconnect the vehicle may
result in a “check Engine” light on the
dash and a Diagnostic Trouble code
being stored in the factory computer,
and the engine may not start.
