"---" 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:

•

•

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):
