Troubleshooting with EconoMind Tuner’s LEDs
Your Banks EconoMind Diesel Tuner
is equipped with diagnostic features
that will detect and display certain
errors. Turn the vehicle key to the
ON position. Observe the two LEDs
mounted on the end of the EconoMind
Diesel Tuner, next to the harnesses.
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. an EconoMind 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 their recommended course of
action for each.
• 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 and stay lit once the
engine coolant temperature is within
its normal operating range.
• No LEDs will illuminate if the fuse
on the EconoMind 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
of if there is a problem with the
system – this sequence will identify
one or more diagnostic codes. a Banks
EconoMind 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 common
diagnostic codes. For example, if a
faulty thermocouple is detected (code
“2,3”) by the Banks 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 diagnostic
code will be eliminated and replaced
by a steady green light.
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.
