• 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.
• 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 or
if there is a problem with the system –
this sequence will identify one or more
diagnostic codes. A 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 common diagnostic codes. For
example, if a faulty thermocouple is
detected (code “2,3”) by the 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 LED. 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.
