Central locking

1. Replace the battery in the remote.
2. Press the button on the remote.. does the little red light on the remote come on when you press the button
3. When you take your key and put it in the lock and twist I right/left do the doors lock?

 

mate.....having the same issue here with no solution yet...could you please check if the lights on your power window switches remain lit even after the keys are turned off?

and does your locking mechanism go "lock,unlock,lock" a few times when you

a) unplug the car batteries and and plug them back on/ turn off the master switch and turn it on )

b) take out the power window fuses and install them back.....(the fuses are in a panel behind the left seat)......

just check and see if this happens.....

 

If the immobilizer function is working properly, and it sounds like it is, you would not be able to start the car if you are unable to have the red light change status and hear the two beeps if it were not. Then it sounds like you have an actuator problem, start with the fuse and move forward from there.

 

Diagnosis on the electrical system is difficult on the internet.. so please bear with us..

So your alarm siren isn't working... and it sounds like your passenger door lock has some issues as well.
To confirm, the drivers door is locking when you turn the key?
You can hear the lock working in the drivers door?
Can you hear the passenger door lock working at all when you turn the key?
I'd still replace the battery in the key fob if you haven't yet. (its a 12v gargae door battery. pretty common and cheap. it can wear out in as little as 6 months, clean the contacts in there when you do and apply dieelectric grease)
To confirm: The red light in the remote fob blinks when you press it? The red light on the left hand dash blinks as well (by the odometer reset button and the sport switch and rear fog lights)?

A burned out and shorted alarm siren can do funky things to the alarm system.

However.. like any electrical issue start simple, and then go complex.
1) Fuses check them and see if they're burned out (fuse 73 and 74 behind drivers seat- see manual for location)
2) The alarm siren is located behind a panel in the front trunk in front of the windshield. Remove it and the alarm is a black thing on the right hand side. There is a plug on the back of it. Pull it out and then try to use your alarm system with the remote.
3) You can open the siren if you'd like and see if the circuit board is good. Its probably toast. GM makes a siren but many don't get an alarm beep. The original siren by ferrari can be expensive. if the electrical board isn't corroded you might be able to replace the internal battery with a rechargable 9V battery.
4) If all the above checks out then its working down the system to the door locks.
5) the siren (esp its battery) is known to be faulty and start with whats known and fix it before going to the unknown..

 

If you just want to hear the "beep" "beep" when you lock the car.. replace the alarm siren.

 

Darn! Was hoping removing the siren might help. At least now you can cut it open and check out the battery and board.

Just trying to discern the symptoms..

When you're in the car and you press down the button on the inner door handle, do both doors lock? Or do they lock and then unlock in the same motion? Oh and if you're outside the car and press the lock button on the remote, do any of the lights flash on the car?

Wondering if its a bad alarm module or other component..

 

BTW not sure if these Volvo alarm modules work.. will have to test one of these days..

Interesting. They should lock at the same time when you press the drivers door tab on the inside of the drivers door. Something is amiss.. I'm not sure if its a lock cylinder thats sticking.. does one lock but the other doesn't?

 

If you want to try to diagnose the problem using the 360 Spider wiring diagram, let me know.


The door locking module is supposed to energize both left and right doors, simultaneously. I suspect that color MV (Brown-Green) is battery (+) in the diagram below; could be color MN (Brown-Black).

At any rate, both colors go to left and right door connectors (1F and 11C) respectively.

And I apologise to continue on this.. but if you press on the remote, do any of door locks make a sound?

Could be the relay that Black 360 is referring to..

Are you comfortable with diagnosing this if its a flaw in the electrical system? I'm just asking..

BTW: the wiring diagram at ferraridatabase.com should help.. fyi the door lock module Black 360 is referring to is this.. below the steering wheel.

You might just want to try reseating the connector into the module. BTW I assume that your car battery is up to snuff and fully charged as Ferrari gremlins love low voltage.

Can you remove the connector and apply 12 volts +/- to the appropriate pins to activate the locks? This will confirm that the module is at fault. If you do just make sure you have the correct pins.
