My son's car is a Seicento Sporting 2002.


I found the two negative pulse wires that control the central locking. Tested them both with 12v light to ground and one wire locked and the other unlocked no problem.

I think the 2 wires touched each other when I got into the car to fit the alarm.


I tested both wires again before starting to fit the alarm and they don't do anything now.


Both doors still lock and unlock with the key.


How can I fix this?

This is sorted now. It was a bad connection.
