Diagnosis - APRILIA SL 750 SHIVER Service Station Manual

SL 750 SHIVER
Tester: set the tester on the "continuity" symbol and place the tester probes on the two circuit ends:
the tester emits a sound signal only if there is continuity; the tester can also be set to the Ohm symbol
to check that the circuit resistance is null or a few tenths of an Ohm.
CAUTION: THE CIRCUIT SHOULD NOT BE ENERGISED, OTHERWISE THE TEST IS IRRELE-
VANT.
GROUND CONNECTION check
Check goal: this control is to check if a cable or a circuit is in contact with the vehicle ground (-)
connection.
Tester: set the tester on the "continuity" symbol and place one tester probe on the vehicle ground
connection (or on the battery - terminal) and the other probe on the cable being inspected: the tester
sends out a sound signal only if there is continuity. The tester can also be set to the Ohm symbol to
check that the circuit resistance is null or a few tenths of an Ohm.
CAUTION! IF THERE IS A GROUND CONNECTION COMING FROM THE CONTROL UNIT, MAKE
SURE THAT DURING THE TEST THE CONTROL UNIT IS EARTH CONNECTED TO THE CIRCUIT.
VOLTAGE check
Check goal: this control is to check if a cable is energised, i.e. if it receives power supply from the
battery or the control unit.
Tester: set the tester on the direct current symbol and place the tester red probe on the cable being
inspected and the black probe on the vehicle ground connection (or on the battery - terminal).
CAUTION
IN CASE OF TEMPORAL MALFUNCTIONING, CARRY OUT ALL DUE CHECKS LOOKING FOR
FAILURES BY MOVING SLIGHTLY THE CABLE HARNESS BEING INSPECTED.
Dashboard
In case the EFI warning light turns on and the words SERVICE or URGENT SERVICE are shown on
the display, due to an error detected in the injection ECU, the malfunction indication will be deactivated
only after the vehicle has been used for a pre-set number of minutes of operation. However, even though
the malfunction is no longer present and the control unit considers the error no longer current but mem-
orised (MEM error indication on Axone), the instrument panel may keep showing there is an error
present.
