Battery Voltage; Battery Voltage Pre Recovery; Battery Voltage P0560 - APRILIA RSV4 R Service Station Manual

RSV4 R

Battery voltage

•
Example value with key ON: 12.0 V
•
Example value with engine on: 14.2 V
In case of recovery, this value is set by the control
unit

Battery voltage pre Recovery

•
Example value with key ON: 12.0 V
•
Example value with engine on: 14.2 V
Value drawn from the signal read without taking
into account any recovery
CAUTION
BE CAREFUL WITH THE POSITIVE BATTERY CABLE - IT
HAS TO GO UNDER THE TOP OF THE FRAME.
CAUTION

DIAGNOSIS INSTRUMENT: LOGIC ERRORS

Battery voltage P0560

•
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 panel does not indicate the presence of this error
even in the ATT status.
Troubleshooting
•
If too high: check correct operation of the voltage regulator.
•
If too low: check voltage regulator connectors, engine - vehicle cable harness connector and
the control unit connector (paying special attention to possible oxidation): if not OK, restore;
if OK, check that red/white cable resistance from the voltage regulator connector to the
control unit connector is a few tenths of Ohm: if not OK, restore cable harness; if OK, check
correct operation of the electrical alternator: if not OK, restore; if OK, check operation of the
voltage regulator
