•
If shorted to positive: disconnect the component, set the key to ON, start the vehicle and
check if the error symptom is still "shorted to positive": it means that short circuit is between
black/white cable and a cable in voltage, therefore restore cable harness; if the error symp-
tom is short circuit to ground, it means that short circuit is inside the valve and therefore,
you must replace the component.
•
If shorted to negative or open circuit: check the component connector and control unit con-
nector: if not OK, restore; if OK, check the continuity of the black/white cable between the
two connectors: if not OK, restore cable harness; if OK, with key ON, check if there is voltage
at PIN 1: if there is not voltage, check orange/green cable; if there is voltage, check com-
ponent electrical characteristics and replace the component
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 dis-
able engine start-up, the switch should be open,
i.e. VEHICLE connector PIN 78 of the Marelli con-
trol unit must not be connected to ground.
Level in wiring diagram:
Start-up enabling switches
Location:
•
on the vehicle: right light switch.
•
connector: inside the bow (4-ways
black).
Electrical characteristics:
•
STOP position: the circuit is open
•
RUN position: closed circuit (continui-
ty)
Pin out:
1 blue/green cable: ground connection
4 yellow/red cable: 5 V
