•
Bus Off.
Error cause:
•
No communication on CAN line (PIN 66 and/or PIN 80): problem in the entire network (for
example interruption or short circuit to positive or short circuit to ground).
This error is indicated by lighting up in a fixed manner the MI warning light.
Troubleshooting:
•
Carry out the Marelli control unit and the engine-vehicle wiring harness connectors check
procedure: if not OK, restore; if OK, check the ground insulation of the two CAN lines from
PIN 66 and PIN 80 of the VEHICLE connector: if not ok, restore the wiring harness; if ok,
check the continuity of the CAN lines from the VEHICLE connector of the Marelli control unit
to the instrument panel connector, or to the LH lights switch connector, or to the ABS mod-
ulator connector: if not ok, restore the wiring harness; if ok, check that the lines are not in
short circuit to positive, testing all 5 connectors (Marelli control unit, engine-vehicle wiring
harness connector, instrument panel connector, LH lights switch connector, ABS modulator
connector) with 1 connector disconnected at a time and turning the key to ON position: If
not OK, restore; if OK, replace the Marelli control unit.
NOTE
THE PRESENCE OF THIS ERROR DETERMINE THE DEACTIVATION OF THE TRACTION CON-
TROL AND THE CRUISE CONTROL.
