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 there
commended 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 reconnected 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.
