Using The Banks PowerPDa
Vehicle Command Center
check the Banks PowerPDA’s
Status Indicator for the “OK” icon.
Any EconoMind Tuner fault will be
indicated by the “Banks Engine” icon
(see Figure 11.1) and its cause can
be investigated by going to the ‘Self
Diagnostics’ screen and scrolling
through the list of logged tuner
events.
1.
Press the center button on the 5-
way navigator to take you to the
System Menu screen.

The ‘Self Diagnostics’ screen
displays a log of diagnostic events
related to the EconoMind tuner (See
Figure 11.3). The ‘Logged Events’ list
takes a moment to update each time
this screen is opened (as indicated
by a slight flickering of the list). Once
the list is updated, the most current
event will appear at the top of the
list. Each event has an associated
timestamp and description, which
will be displayed below the list when
that event is highlighted. Each key
cycle of the vehicle produces a
minimum of two logged events.

Diagnosing EconoMind error
codes without the PowerPDa.
If you feel that your Banks EconoMind
Diesel Tuner is not functioning
properly, some diagnostics can be
performed. Your EconoMind Diesel
Tuner is equipped with diagnostic
features that will detect and display
certain errors.
Remove the Banks EconoMind Diesel
Tuner from its mounting location
while keeping all connectors plugged
in, and position it in such a way
that you can view the end of the
EconoMind housing that contains
the LEDs from the driver’s seat. Turn
the vehicle key to the ON position.
Observe the two LEDs mounted on
the end of the Banks EconoMind
Diesel Tuner:
• 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 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.
