Ai606 Central Locking Fault
 

Hi folks

For some reason the central locking has gone wrong, it locks occasionally but wont unlock at all via the remote, all wires/fuses/motors are fine.

Is it possible the main alarm unit is at fault?

Pop drivers door card of there will be an aftermarket motor fitted to drive original locking this may have come loose or slipped on locking bar
If you take card off all will become clear

Thanks for the reply Ian, had someone test the wires to the universal motor and the lock wire has voltage to it both on lock and unlock, the unlock wire has nothing at all?

Checked all the necessary cables for live and earth for the central locking and they are fine?

So the grey/red wire has 12 on lock and unlock

Ian

Yes 12v on lock/unlock but nothing on the other wire on lock unlock.
When installed it worked fine and nothing has been altered or anything, all i can assume is a internal fault with the alarm :(

Helen

Could be

I have spare control boxes and remotes if that helps

Have you tested the output at the alarm control box or at the motor
may be worth trying that
