pleted, the LED remains permanently OFF. The
engine can be started.
5. Decoder programmed - fault detected: a light code is displayed according to the fault detected,
after which the LED remains on steadily. The engine cannot be started. The codes that can be trans-
mitted are:
•
1-flash code
•
2-flash code
•
3-flash code
Diagnostic code - 1 flash
The one-flash code indicates a system where the
serial line is not present or is not detected. Check
the Immobilizer aerial wiring and change it if nec-
essary.
Diagnostic code - 2 flashes
A 2-flash code indicates a system where the de-
coder does not recognise the transponder signal.
This might depend on the inefficiency of the im-
mobiliser aerial 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. Oth-
erwise replace the faulty key and/or reprogram the
decoder. If the problem persists, replace the de-
coder.
