7.3 - ERRORS
In case of a problem, the device shuts down and the display will show one error message from the following list.
Message Description Troubleshooting
E1
Battery voltage
(The battery-saver has activated. Voltage
decreased below the set threshold.)
Start the vehicle in order to recharge the
battery.
E2
Power overload from the evaporator fan
(The evaporator fan overloads the board
beyond the allowed limit. Possible cause: short
circuit or something is blocking the fan from
rotating.)
Take the system to an authorised dealer.
E3
Blocked compressor
(The rotor is blocked or the pressure in the
cooling circuit is too high.)
E4
Minimum compressor rotation speed
(If the cooling circuit is overloaded, the
compressor is unable to maintain minimum
rotation speed.)
E5
High temperature in the control board
(If the cooling circuit is overloaded or if the
surrounding temperature is too high, the control
board signals this issue.)
The presence of
E3 – E4 – E5
codes do not
indicate a malfunction, but is a normal
management procedure for the compressor by
the electronic board. Only if the code continues
to be displayed contact an authorized dealer.
E6
Communication error
(No communication between the display and the
control board.)
E7
Temperature probe
(If the probe has short circuited or has become
disconnected, the system stops working.)
E9
Power overload from the condenser fan
(The condenser fan overloads the board beyond
the allowed limit. Possible cause: short circuit or
something is blocking the fan from rotating.)
Take the system to an authorised dealer.
