Electrical system
Diagnostic code - 1 flash
A one-flash code indicates a system where the se-
rial line is not present or is not detected. Check the
Immobilizer antenna wiring and change it if nec-
essary.
Diagnostic code - 2 flashes
A two-flash code shows a system where the con-
trol unit does not show the transponder signal. This
might depend on the inefficiency of the immobilizer
antenna or the transponder.
Turn the switch to ON using several keys: if the
code is repeated even with the Master key, check
the aerial wiring and change it if necessary. If this
is not the case, replace the defective key and/or
reprogram the control unit. Replace the control unit
if the problem continues.
Diagnostic code - 3 flashes
A three-flash code indicates a system where the
control unit does not recognise the key. Turn the
switch to ON using several keys: if the error code
is repeated even with the Master key, replace the
control unit. If this is not the case, reprogram the
decoder.
Battery recharge circuit
The charging circuit consists of three-phase alternator and a permanent magneto flywheel.
The generator is directly connected to the voltage regulator.
This, in its turn, is connected directly to the ground and the battery positive terminal passing through
the 30A protective fuse.
