"---" code that indicates an instrument panel error
Air temperature sensor fault
Error cause
•
An instrument panel temperature sensor failure is signalled when it is detected that the
sensor circuit is open or shorted to positive/negative
Troubleshooting
•
Check the sensor connector and the instrument panel connector (PIN 12): if it is not OK,
restore; if it is OK, check the continuity of the pink cable between the sensor connector (cable
harness side) and the PIN 12 of the instrument panel connector: if not OK, restore the cable
harness; if OK, check the correct sensor resistance: if it is not OK, replace the sensor; if it
is OK, with key set to ON, check if there is voltage at the sensor connector PIN 1: if there is
no voltage, replace the instrument panel; if there is approximately 12V, restore the cable
harness (there is a short circuit in the battery). If there is 5V voltage, connect a 10 kOhm
resistance to PIN 1 of the sensor connector and to the vehicle ground connection: if, with
key set to ON, the voltage measured upstream the resistance decreases, replace the in-
strument panel. If voltage continues to be approximately 5V, restore the pink cable (there is
a short circuit at + 5V). In case there is a short circuit to ground connection of PIN 12 of the
instrument panel connector: Check the earth insulation of the sensor connector pink cable:
if there is a connection, restore the cable harness; if it is earth insulated, check that sensor
resistance is correct: if not OK, replace the sensor; if it is OK, replace the instrument panel
RUN/STOP switch
Function
It tells the control unit if the driver wishes to enable engine start-up or to keep the engine running.
Operation / Operating principle
If the driver wants to shut off the engine or to disable engine start-up, the switch should be open, i.e.
the Marelli control unit should not detect voltage at PIN 26 of the control unit connector.
Level in wiring diagram:
Start-up enabling switches.
Location:
•
sensor: right light switch
•
connector: near the headstock, right side
Electrical characteristics:
•
STOP position: the circuit is open
•
RUN position: closed circuit (continuity)
PIN:
red/grey cable (watching the cable harness):
