Code 1
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.
Code 2
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.
Code 3
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.
