network (for example, battery cut-off or short circuited or shorted to ground).

Troubleshooting

•

Check the Marelli control unit VEHICLE connector: if not OK, restore; if OK, check the earth

insulation of the two CAN lines from PIN 20 and PIN 51 of the VEHICLE connector: If not

OK, restore the cable harness; if OK, check continuity of the two CAN lines from the Marelli

control unit VEHICLE connector to the filter casing large connector and to the instrument

panel connector: if not OK, restore the cable harness; if OK, check that the two lines are not

short circuited to positive testing each of the 3 connectors (Marelli control unit connector,

filter casing large connector and instrument panel connector) with 1 connector disconnected

at a time and by setting the key to ON: If not OK, restore; if OK, replace the Marelli control

unit.
