U1602 CAN line without signals - Bus Off.
Error cause
•
No communication on CAN line (PIN 20 and/or PIN 51 VEHICLE): problem on the whole
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 ground
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 box large connector and to the instrument panel
connector: if not OK, restore the cable harness; if OK, check that the two lines are not shorted
to positive testing each of the 3 connectors (Marelli control unit connector, filter box 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.
