EconoMind Troubleshooting using
the Tuner’s LEDs.
(With or without a Banks iQ Installed)
If you feel that your 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 EconoMind Diesel Tuner
from it’s 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 (Figure 53). Turn the vehicle
key to the ON position. Observe the
two LEDs mounted on the end of the
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 it’s
normal operating range.
