Fault codes
Dds: no fault code displayed.
Dashboard: no fault code displayed.
Location of connections and components
(A) low / high beam and parking light connections rear running light and stop light connection.
Pin numbering of wiring harness side bbs unit connection.
Checks
The front and rear parking lights use led light units and receive a 12 v power supply. Power the parking lights with an external 12 v power supply to test function (connect correctly as indicated in the wiring diagram).
Check congruence of the ground connection on the running lights.
Check that the parking lights receive 12v arriving from pin 7 of the bbs.
Check the integrity of the electrical circuit and connections (short-circuits to ground, short-circuits to vdc, open circuits).
If none of the aforementioned tests identifies the problem, replace the bbs.
Note
Check integrity of electric circuit - short-circuit to vdc = with dashboard on, using a voltmeter, a voltage is measured between the wire tested and ground.
Check integrity of electric circuit - short-circuit to ground = with the battery cables disconnected, using an ohmmeter, continuity is detected between the wire tested and ground.
Check integrity of electric circuit - open circuit = with the battery cables disconnected, using an ohmmeter, no continuity is detected between the two ends of the wire tested.
Lubricating cables and joints
Check the outer sheath of the throttle control and cold start
lever cables for damage at regular intervals. The outer plastic
cover should not be flattened or cracked. Operate the
controls to make sure the inner cables slide smoothly inside
the outer sheath: if you feel any friction or catching, ...
Rectifier-regulator
The rectifier (1) is placed in the electrical components compartment.
The rectifier/regulator consists of an aluminium casing containing the diodes
that rectify the current produced by the
alternator. It also contains an electronic device that regulates the current
supplied by the alternator ...
Hands free key (hf) not recognised
The activation of this (amber yellow) "warning" indicates that the hands free
system does not detect the active key (1,
fig.62) Near the vehicle.
Note
Check that the active key (a) is near the vehicle (and has not been lost)
or that it works properly.
