• The GREEN LED will flash if all wire

connections are correct, the engine

is running, but the engine coolant

temperature is not within it’s normal

operating range. The GREEN LED will

stop flashing once the engine coolant

temperature is within it’s normal

operating range (not to be confused

with Speed-Loader flash on power-up).
• No LEDs will illuminate if the fuse

on the Six-Gun wiring harness is

blown or the wiring harness is not

properly connected. If the fuse and all

connections are okay, contact Banks

Technical Service.
• The RED LED will flash in a certain

sequence if a connection is incorrect

or if there is a problem with the

system – this sequence will identify

one or more diagnostic codes. 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 common

diagnostic 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 diagnostic

code will be eliminated and replaced

by a steady green light. If the 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.
