Introduction
The communication antenna enables the hands free system to detect and communicate with the active or passive key.
The active key is detectable within a range of 1.5 Metres, whereas the passive key (or active key with flat battery) can only be detected if placed in contact with the lower part of the clear plexiglas windscreen covering the antenna.
An antenna fault will compromise correct key detection.
Wiring diagram

The communication antenna is connected to the hands free system by two cables and a dedicated connection.
Error codes
"Hands free diagnosis" error: "antenna": antenna not detected (open circuit)
or antenna short circuited. The following icon
appears on the tank dashboard:
Note
Checking the integrity of the electrical circuit entails the following actions:
Short circuit to vdc: with the dashboard on, use a voltmeter to measure the voltage between the wire being tested and ground.
Short circuit to ground: with the battery cables disconnected, use an ohmmeter to check for continuity between the wire being tested and ground.
Open circuit: with the battery cables disconnected, use an ohmmeter to check that there is no continuity between the two ends of the wire being tested.
Electrical characteristics and checking component
The resistance between the two terminals of the component side connection must be approximately 2 ohm.
In the event of fault
In the event of a component fault, the hands free system can no longer detect and recognise the keys. The pin code procedure must be used to start the motorcycle.
Installation location

Component replacement methods
No special measures are necessary in order to replace the hands free system communication antenna.

Overhaul of the connecting rods
Make the following dimensional checks on the connecting rods:
Clearance with gudgeon pin on assembly.
In the event of excessive wear (sect. 3 - 1.1, Crankshaft), replace the
connecting rod.
The small end bushing must be in good condition and firmly driven into its seat.

Chain lubrication
The chain fitted on your motorcycle has o-rings that keep dirt
out of and lubricant inside the sliding parts.
So as not to damage these seals when cleaning the chain,
use special solvents and avoid aggressive washing with highpressure
steam cleaners.
After cleaning, blow the chain dry with ...
