In case of a fault that aff ects the automatic regulation, the control unit displays an error code consisting
of the letter

followed by a number which identifi es the type of fault according to the following Table::
E 1
external air temperature sensor (E.T.) interrupted.
E 2
external air temperature sensor (E.T.) short circuit..
E 3
cab air temperature sensor (I.T.) interrupted..
E 4
cab air temperature sensor (I.T.) short circuit.
E 5
