Electrical system
PAY ATTENTION TO THE POSITIVE BATTERY CABLE,
WHICH MUST PASS BELOW THE UPPER PART OF THE
FRAME.
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING,
CAREFULLY READ THE GENERAL TROUBLESHOOTING
CONCEPTS FOR ELECTRICAL DEVICES AT THE BEGIN-
NING OF THE CHECK AND CONTROL SECTION IN THE
ELECTRICAL SYSTEM CHAPTER.
DIAGNOSTIC TOOL: LOGIC ERRORS
P0560 Battery voltage
•
too high/too low
Error cause
•
If too high: too high a voltage has been detected at PIN 42. If too low: too low a voltage has
been detected at PIN 42.
The instrument cluster indicates the presence of this error with the MI warning light on fixed.
Troubleshooting
•
If too high: check that the voltage regulator is working correctly.
•
If too low: check voltage regulator connectors, engine-vehicle wiring harness connector and
ECU connector (check in particular for oxidation): if not OK, repair. If OK, check that resist-
ance of the Red/White cable from the voltage regulator connector to the ECU connector is
a few tenths of an Ohm; if not OK, repair the wiring harness. If OK, check that the alternator
is working correctly: if not OK, repair. If OK, check that the voltage regulator is working
correctly
P1560 Low battery voltage error - GCC error
Functional diagnosis:
•
low voltage
Error cause
•
The error is enabled if, after 5 seconds from the key to ON, the battery voltage is judged low
by the ECU.
•
Low voltage detected to PIN 52 of the Marelli ECU.
The presence of this error is signalled by the fixed lighting of the general warning light.
Troubleshooting
•
Try charging / replacing the battery: if NOT OK, carry out the check procedure for the alter-
nator connector and the control unit connector (paying particular attention to any oxidation):
if not OK, restore. If OK, check that cable resistance between the alternator cable and the
control unit is a few tenths of Ohm: if not OK, repair the wiring harness. If OK, check that
the alternator is working correctly: Restore if not OK.
