355 1997 Ferrari 355 spider 5.2 - Central Locking Issues.

I have a problem with my central locking system. When you open the car was the remote fob the door lock pins hop up and down as opposed opening the car. I have replaced both the central locking motors in each door already. I have cleaned all the connections for the switches. I can lock the car but I cannot open the car with the fob, as they always hop when you try to open the car..

I was wondering if the door catch would affect the central locking system as I recently had to tighten the driver’s side door catch as it had come loose.

Is it potentially a faulty central control box?

Any ideas or suggestions appreciated.

 

Qavion,

Thank you for the input, if I use the console switches to unlock the door I still get the same hopping problem. I have removed the switches and I still cannot unlock the doors and the hopping problem persists. I have not been able to loosen the drivers door catch as the door is not currently and I cannot access the door catch. I will have a look at the ECU in the foot well, as I have not checked that yet.

 

Qavion,

Funnily enough, I can open the passenger door by holding up the the central locking button on the door. This will not work on the drivers door and the drivers catch was the one that I adjusted.

My car is right hand drive.

Central locking Issue Summary.
Central locking hops constantly on closure or opening via the remote key fob.
I can manually hold down the door buttons when they are hopping into the locked position.
I can't manually hold open the door buttons when they are hopping.
If I manually lift the door buttons I can open the passenger door but I cannot open the driver's door.
Once the passenger door is open it will still keep hopping as before unless I pushed the buttons down to the locked position.
I get no different behaviour in the passenger and driver's door lock
I have not checked the ECU yet, I think I have a spare somewhere.

 

OEM Ferrari. They had previously worked well.

 

Waiting for parts currently.

 

Typical, I have tried to order the Ferrari 355 Central Locking Module (ECU). I have been told that this is no longer available from Ferrari. Currently they are doing a worldwide part search to see if they can find one in stock.
I wonder whether you can repair these units or is the only choice to source a second-hand used ECU. I don't know whether it's me but whenever I start a job on the 355 it always seems to get complicated.

Any bright ideas?

 

I found a dry joint and soldered it and it is working now, it was pretty basic inside. I still have a problem with locks hoping, I think that this is related to the
Drivers door catch that has moved which is causing the lock to stay closed on the catch. I have read a thread about this on F Chat that explains that if the door striker is in the wrong position when the door is closed it will cause the central locking to hop.
The challenge is I cannot open the driver's door with the internal or external opening mechanism, somehow I need to change the door position to relieve the pressure off the striker that locks the car.
Not had this problem before usually they become loose over time. Perhaps the solution is to drive round for a few hundred miles until it come loose which they normally do!

thanks appreciated

 

I have fixed the central locking module but i can not get the drivers door claw lock to open that connects to the door post connection on the drivers side. I can open passenger side but the locks are still hoping, even with the passenger door open.

Remote wont open doors only causes hopping lockes
Key wont work
Door opener will not work
Removed fuse still no luck
Manually held central locking open, wont open.

I think it an alignment problem between the door claw lock and the door post connection.

Any idea appreciated.

 

The problem as you cant remove door card, door opener or scoop with the door closed without damaging door card or scoop. The actuator is new.

I do appreciate the help, when you have a problem, thanks.
