- RECOMMENDATIONS TO THE INSTALLER
1- Explain to the user how the system works. Provide the user with the following elements: User's
Manual, N/F 3/8" plugs, straight joint 5/16", fastening nuts and hose provided with the system.
2- Inform the user that each time a tire is replaced it should have a pressure lower than the calibration
pressure. The system only provides air to tires, it does not deflate tires.
3- Remind the user that rotor centring must be checked each time that a hub is dismounted to repair the
brakes, to make bearing adjustments or replacements, etc.
4- Remind the user that the excess pressure generated by rolling must not be higher than 12% of the cold
calibrated pressure. If the display indicate a pressure higher than that percentage, the user must verify
whether the pressure is generated due to system failure or by rolling, proceeding as follows:
- Disconnect one or more tires from the system.
- Drive until display readings for connected tires exceed the specified tolerance. Compare
pressures of connected and disconnected tires with a tire gauge.
- If the pressures are similar, rolling causes the increase. If pressures differ, there may be
damage to the control module. See "Failure location guide" in next section.
7 - FAILURE LOCATION GUIDE
To quickly trace an air leak turn the system off and:
a) If the display reading falls quickly, the leak is located in the system network between the VIGIA tire
valve and the control module.
b) If the display reading falls very slowly, the leak is located in the tire (puncture) or a VIGIA tire valve is
defective or loosely attached to the tire stem.
PROBLEM PROBABLE CAUSES SOLUTIONS
Loss of pressure in display.
With the system disconnected,
the reading
falls slowly
.
1-Small pressure loss in one
or more tires. Punctured tire.
2-Small loss between the
original tire valve's thread and
the VIGIA tire valve.
1 - Repair the affected tire.
2 -a) Adjust the VIGIA tire
valves lightly with a wrench.
b) Replace the VIGIA tire
valve's joint.
c) Check the original and
VIGIA valves' thread (clean
with a threading tool). Replace
if necessary.
