IL TEMPERATURE CIRCUIT SENSOR
When the Engine Temp. item on the Dashboard Monitor
page displays an error, this meas that the electrical circuit
going from the potentiometer to the ECU is interrupted;
this means that:
The sensor is damaged or the wires are cut out; it is
therefore necessary to check the connections and the
sensor's resistance; if the sensor is damaged, replace
it as described in chapter 15 in this section;
On the rare occasion that the circuit inside the ECU is
interrupted: replace the ECU following the instructions
described in chapter 13 in this section.
It is possible to carry out a further test on the signal
coming from the sensor using the Dashboard Monitor front
page. In fact, the engine temperature is displayed in the
middle of the page. When the engine is cool, this can
easily be compared with the external temperature.

IR TEMPERATURE SENSOR CIRCUIT
When on the Dashboard Monitor page, the Air Temp. item
displays an error, this meas that the electrical circuit from
the potentiometer to the ECU is interrupted; this means
that:
The sensor is damaged or the wires are cut.-out: check
the connections the sensor's resistance. If the sensor
is damaged replace it as described in chapter 14 in
this section.
On the rare occasion that the circuit inside the ECU is
interrupted: replace the ECU following the instructions
described in chapter 13 in this section.

ATTERY VOLTAGE
An icon will appear on the bottom LH part of the Dashboard
Monitor front page. Here the user will easily view the voltage
on the battery terminals, which can be therefore checked
immediately.
