R Disconnect the filling nozzle from the tire and connect it back to tire. Ensure
that the hose is connected to the digital outlet port.
R Check if there is leakage at the connector. If there is leakage, the clip should
be tightened.
Check the set pressure value. It should be equal to or lesser than 65 psi.
Contact customer service.

R Check tire pressure and ensure that it is within recommended range.
R Refer and execute actions described for error 1.
R Ensure sufficient tank pressure/inlet pressure during filling.
R Pressure sensor may not be functioning. Contact customer service.

of the following reasons:
R Leakage at the CMS tank outlet.
R Failure of non-return valve.
R Bursting of the pneumatic pipe at the output
of CMS tank.
R End fittings of the nitrogen tank are loose.
R Safety valve is loosely connected.
R Burst or leakage in the pneumatic pipe at the
output of nitrogen tank.

nal block.
R Connect the LCD connector to connec-
tor on the control board.
R Contact customer service to replace
the control board.
