Run/Stop
NOTES
•
Indication on the diagnostics instrument always on STOP: disconnect the connector and,
with the switch set to RUN, check if there is continuity towards the two cables switch - Blue/
Green and Yellow/Red: If there is not continuity, replace the sensor; if there is continuity,
check the connector: if not OK, restore the cable harness; if OK, check, with key set to ON,
if there is voltage on Yellow/Red cable: if there is no voltage, restore the cable harness; if
there is, check the Yellow/Red cable ground insulation: If there is continuity with ground
connection, restore the cable harness; if OK, set the key to OFF and check the VEHICLE
connector and the engine-vehicle cable harness connector: if it is not OK, restore; if it is OK,
check the continuity of the Yellow/Red cable between the switch connector and VEHICLE
connector PIN 78: if not OK, restore the cable harness; if OK, replace the Marelli control
unit.
•
Indication on the diagnostics instrument always on RUN: disconnect the connector and, with
the switch set to STOP, check if there is continuity between the two cables of the switch: if
there is continuity, replace the switch; otherwise, it means that, with key set to ON, the
Yellow/Red cable (between switch and the PIN 78 of the control unit connector) is shorted
to positive: restore the cable harness.
Butterfly valve in exhaust
Function

exhaust system at high revolutions.
Operation / Operating principle
The system consists of a throttle valve with a re-
