CLF control unit connector pin 9. If NOT OK, change the vehicle cable harness; if OK, check
the continuity across inertia sensor platform (Sensor box) connector pin 3 and CLF control
unit connector pin 8. If NOT OK, change the cable harness; if OK, check for the correct
power supply (12V) at pins 1 and 2 and ground at pin 10 of the CLF control unit connector.
If NOT OK, restore the cable harness; if OK, change the instrument panel.
DIAGNOSIS INSTRUMENT: LOGIC ERRORS
CAN line toward CLF control unit U1711
•
No signal/Configuration error
Error cause
•
With no signal, no signal is received from the CLF control unit. In case of configuration error,
some devices are present (e.g. CLF) that were not foreseen in the vehicle configuration
stored in the control unit.
Troubleshooting
•
No signal - Check the pins 8 and 9 of the CLF control unit connector, vehicle-engine con-
nector pins B2 and B3 and Marelli control unit vehicle connector pins 66 and 80. If NOT OK,
restore. If OK, with key OFF disconnect the following: a) CLF control unit connector, b) inertia
sensor platform (Sensor box) connector and check the continuity across inertia sensor plat-
form (Sensor box) pin 3 and CLF control unit pin 9. If NOT OK, replace the vehicle cable
harness; if OK, check the continuity across inertia sensor platform (Sensor box) pin 2 and
CLF control unit pin 8. If NOT OK, replace the cable harness; if OK, check for the correct
power supply (12V) at pins 1 and 2 and ground at pin 10 of the CLF control unit. If NOT OK,
restore the cable harness; if OK, replace the CLF control unit.
•
Configuration error - Open the Navigator devices status page to check if the control unit
setting is actually consistent with the motorcycle setting. Example: if the bike is equipped
with CLF control unit, the correct status we should find on the Navigator devices status page
will be: Aprilia Traction Control PRESENT. While on a bike equipped with CLF control unit
and Navigator indication: Aprilia Traction Control NOT PRESENT update the control unit.

No signal/Configuration error
Error cause
•
If there is no signal, no signal is received from the inertia sensor platform (Sensor Box control
unit). In case of configuration error, some devices are present (e.g. Sensor Box) that were
not foreseen in the vehicle configuration stored in the control unit.
Troubleshooting
•
No signal - Check the pins 2 and 3 of the inertia sensor platform (Sensor Box) connector,
vehicle-engine connector pins B2 and B3 and Marelli control unit vehicle connector pins 66
and 80. If NOT OK, restore. If OK, with key OFF disconnect the following: a) CLF control
