Check the pins 66 and 80 and the Vehicle connector of the Marelli control unit. If not OK,
restore. If OK, check pins 5 and 6 and the ABS control unit connector. If not OK, restore. If
OK, check overall operation of the Marelli control unit and ABS control unit: replace the
affected component if you find any fault.
DIAGNOSTICS INSTRUMENT: LOGIC ERRORS
CAN line towards ABS control unit U1711 - No signal/Configuration error
Error cause
•
If there is no signal, no signal is received from the ABS control unit. In case of configuration
error, some devices are present (e.g. ABS) that were not foreseen in the vehicle configura-
tion stored in the control unit.
Troubleshooting
•
Open the diagnosis tool devices status page to check if the control unit setting is actually
consistent with the motorcycle setting. Example: if the bike has an ABS system the correct
state that should be found in the diagnostics instrument device status screen will be: Aprilia
Traction Control present. In the event of a bike with ABS system present and indication of
the diagnostics instrument of: Aprilia Traction Control not present, update the control unit.
VCU ERRORS
Failed CAN reception from motor ECU C1300
Error cause
•
The VCU does not receive the signal from the motor control unit.
Troubleshooting
•
Check the continuity of the cable between PIN K2 VCU - PIN 66 VEHICLE motor control
unit and between PIN J2 VCU - PIN 80 VEHICLE motor control unit. The error is automat-
ically memorised when the communication between the two control units is restored. To exit
the diagnosis status and allow the VCU to resume operation in normal conditions, it is how-
ever necessary to switch from «OFF» to «ON».
Failed CAN reception from instrument panel C1301
Error cause
•
The VCU does not receive the signal from the instrument panel.
Troubleshooting
•
Check the continuity of the cable between the PIN K2 VCU - PIN 27 instrument panel (black
connector) and PIN J2 VCU - PIN 26 instrument panel (black connector). The error is au-
tomatically memorised when the communication between the two control units is restored.
To exit the diagnosis status and allow the VCU to resume operation in normal conditions, it
is however necessary to switch from «OFF» to «ON».
