1) Why is my system not powering up?
When the system does not power up, usually this is a strong indi-
cation of improper power and grounding. Ensure that the power
line (red wire) is attached to a +12 volt power source (battery). The
grounding line (black wire), should be rerouted back to the battery,
not the frame of the car. Traditionally, techs have used the frame
the car as a grounding source, but through experience, we have
seen that using the true ground (battery) offers the best connection
for the device. Next, ensure that the yellow line is connected to the
ignition fuse located in your vehicles fuse box. Please make sure
the fuse on the F3 wiring harness is installed and not blown. It is
important to confirm with a meter (if possible) that the fuse is on
only when the ignition is engaged and off when the ignition is off.
2) Why are my buttons not responding correctly?
When your remote controller appears to not operate as intended,
some of the key items you need to check are: battery charge (+3v),
proper connection to the ECU, EC/N Code (refer to #7), barriers that
are in between the ECU and the remote, proper powering (refer to #1).
3) Why is my compressor not shutting off?
When your compressor stays on even after the ignition switch has
been placed to the off position, please ensure that the yellow line is
tied to a switched fuse in the fuse box. To ensure this, please use a
volt meter to confirm that the line is on (+12v), if and only if the igni-
tion switch is in the ON position, and OFF when in the off position.
4) My remote does not work inside my cabin. What should I do?
With the improvements in technology, some cars are equipped
with other electronic equipment which may cause interference to
the F3 system. Others vehicles are equipped with noise canceling
material and equipment which also play a role in the interference
of the F3 connectivity. To check if either of these scenarios is true,
confirm that your unit works properly if operated outside. If your
unit does operate as intended outside the vehicle, contact us for
further solutions.
5) Why does my system not turn on when I turn the ignition on?
When your F3 system does not turn on when the ignition switch
is on the on position, this is a strong indicator that the unit is not
powered/grounded correctly. Please refer to question #1.
6) Why does my remote freeze when I am trying to change pressure?
When your remote is freezing, this is an indication that the com-
munication is out of range/ batteries have insufficient charge or
you may have a bad remote. If the batteries are low, replace the
batteries. If the communication range is over 30 meters, operate
the unit in close proximity. If the issue still persists, contact our
tech line to receive a replacement. In order to receive a placement,
please have your receipt to show proof of purchase.
7) Why does my remote display "E/CN" when attempting to
change pressure?
The "E/CN" code is an indicator that the remote is not communi-
cating to the ECU. When this occurs, this is an indicator that the
ECU is not powered or the user is out of range. When the ECU is
not powered, please refer to question #1. If the user is out of range,
ensure to get within the range of 30meters (98 feet).
8) What should I do when the remote goes to sleep before it meets
the set pressure?
Check battery voltage.

FREQUENTLY ASKED QUESTIONS
9) Is it normal for my compressor to be overworking when at-
tempting to reach pressure?
When the compressor sounds as if it is overworking to get to
pressure, relax. This is normal. The ECU was programmed to reach
the designated pressure as accurately as possible. To reduce the
over usage of the compressor, use the system only when needed.
Having two preset settings will reduce the over usage and increase
the system lifetime.
10) Why does my compressor run while exhausting continuously?
When the compressor exhausts while running, ensure that the
air line connections to the ECU are correct. The ECU has a sup-
ply and exhaust line. If the unit is connected backwards, the ECU
will attempt to reach pressure, but won't since the connection is
improper. If the issue persists after confirming proper connection,
check the valves next. The valve could have debris which is not al-
lowing the valves to properly close. If shop air is available, engage
the valves with air to free the valves of debris. If the issue persists,
please contact tech line for warranty claim.
11) Why does my compressor turn on and run by itself while driving?
If the compressor turns on by itself while the vehicle is in motion
and continuously runs, there is a relay that is energized by the bat-
tery, and there is a potential wiring harness connection problem.
It is possible that the ground terminal of the harness is improperly
connected, or has become loose. Please check the connections of
the harness to ensure that all terminals are properly connected. If
all connections are secure and properly connected, please check
the integrity of the relay connection to the compressor. It may be
possible that the relay
is failing or has failed.
12) Why does my compressor still run when I turn the key off, even
when wired to an ignition source?
Please confirm that the following are connected correctly:
A: The yellow ignition wire is properly connected to the correct
fuse that connects to a switched source. There are some fuses
that are always powered even when the vehicle's ignition is
turned off.
B: The red power wire is properly connected to the battery,
preferably directly to the battery terminal to ensure that the
relay is properly energized and reenergized during turn-on,
turn-off cycles.
C: The black wire is properly attached to a ground path. A direct
battery connection to the negative terminal is preferred.
13) Why does my compressor run, but dead heads at the ECU?
The compressor usually stops operating if there is an improper
connection to the valve body inlets and outlets. If your compressor
runs momentarily and then stops, please check the following:
A: The battery on the vehicle is in good working condition. It has
been observed that batteries with insufficient capacities have
been unable to withstand compressor demands. Please check
your compressor's power rating, and confirm that the battery
can meet the voltage and current demands.
B: Please confirm that the air lines are connected to their proper
inlet or outlet valves. This will enable the compressor to properly
operate as demanded by the user's input.
14) Why does my controller show a completely different pressure
than what is actually in the bags?
When the controller shows a completely different pressure, please
contact our tech line for a warranty claim. The ECU contains pres-
sure sensor which can be faulty. Since the sensors are inside the
ECU, the unit needs to be replaced.
