Engine kill after battery died on 2001 550

The car will not run if the battery is completely drained. Even with a jump, to stay running the battery will have to have something to offer after the cables are removed.

If your battery has been "completely drained", give it a good charge and you should have success.

Good luck.

 

Duane- It is always a good idea not to jump a Ferrari. Probably no problem, but might cause ECU problems. The Airbag ECU is particularly susceptible to damage. If your battery is completely drained, the best idea is to use the disconnect switch and then charge the battery using a regular charger. Then reconnect the battery and see what you have. You can do the same thing using your friend's car if he is willing to leave it running long enough to charge the battery with the disconnect switch in the off position.

Like Brown said, a low battery can cause all kinds of problems even if you do get the car running. It acts like a huge resistor instead of an integral part of the system.

If all else fails, here is a document on replacement batteries. Still missing the Braille battery now listed by Ferrari as a replacement. Will have to add it.

Right under the right headlight is the siren. Just pull the plug on the thing. It is a useless POS anyway. Then disconnect the battery and charge it overnight on the charger. It may or maynot hold a charge. Then reconnect and try to start the car. Or use the disconnect switch by the right fender then charge battery then try to start car. I don't understand what you are doing with the pin code. You should not have to use that at all. The battery in the fob is not effected by the car battery. Once the battery is reconnected the alarm ecu will recognise the FOB assuming there is no way for you to mess that up because you were messing with the PIN entery system with a dead battery.

 

Duane- 120 seconds after you use the PIN code and do not start the car, the immobilizer rearms itself, so there is no advantage to doing that except to start the car.

FBB- The latest siren has a completely different type of battery and has caused virtually no problems. What Duane was seeing was the alarm system reacting to an attempt to drain the battery and then steal the car. A technique widely use on C4 Corvettes where a hole was drilled through the bottom of side of the battery. That is what the siren's rechargeable battery is supposed to do. Unfortunately, when the battery is low, the remote may not shut it off if the Alarm ECU does not see its signal.

Taz,

That is so funny. Why can't these smart creative thieves use their powers for good rather than evil?

 

FBB- The first time they are busted and go to prosion, they enter a graduate degree program for thieves. They compare notes, teach each other the latest techniques for disarming burglar alarms, car alarms, etc and learning which car models are the most profitable and easiest to steal. They gain contacts who help them fence or strip and fence what they steal. They are career criminals and that is what they do for a living.

Great world, no?

Hi

Some similar probs at my 99 550.

After a dead battery (10 V), changing to another battery, a 74 AH from my Alfa Romeo which is in new condition (with using the switchoff knob), i have some strange behaviors. Also the battery from the remote is new.

The car runs. This is the good thing.
When i close or open the doors, there is no beep from the sirene.
The red LED in the inside is glowing when key goes from 0 to 2, stops glowing after starting the engine and starts to glow again when the car runs.

When i use the battery switch off and disconnect the battery, the alarm sirene starts to work. It stops only after connecting the battery.
So the batteries from the alarm sirene are OK.
Manual says that a door or boot could be open and send a bad signal, but the check says : all closed.

Should i drive some Kilometers, perhaps the problem will be gone ?
The car was standing for 6,5 months, battery was cutted off, car got new clutch, flywheel, throw out bearing, engine mounts, oil, filters, ........
With the bad battery, the sirene worked at open/close the doors with the fob, but an alarm with 4 or 5 beeps followed, starting was not possible with the 1 cell dead. Think this was normal.

My neighbour told me, that he have heard the alarm 2 days before, new battery was installed since 1 week (nobody was at home), car stands in closed garage, no one can get in. He didn't know how long, it can be 15 minutes, it was not loud in the closed garage.

Any ideas ?

Daniel- Sounds like the alarm siren is gone or the siren battery is discharged. Common problem and the alarm going off may have finished off or drained the siren battery. Try driving her and see if the siren battery will recharge. It only charges while the engine is running.

Terry, when i cut the battery, the alarm works, isn't this sirene not the same as the sirene for the beep ? Today the season starts, so i can drive some Km.
I will update you this evening.

Daniel

 

Yes, it is the same siren! Strange behaviour...
The red light on the instruments panel indicates that the siren's battery is not charging properly, so maybe yours still has some charge left to produce sound but will be flat very soon.

Terry - the siren can recharge its battery even if the engine is not running. My 550 has a factory mod which connects the main battery's negative terminal directly to the siren unit, bypassing the cutoff switch. This was done to avoid the siren's battery to drain completely when the main battery is cut off for long periods in winter.

Daniel - check that your car has two cables from the negative terminal on the battery, one to the cutoff switch and a smaller one to the siren. If not have it installed!

Stefano- Thanks. Did not know that.

Hi all

I think i have found the problem. I have to check it the next days.
Stefano (maranello72) gave me an essential advice.

But first, once again the complete symtoms.
All functions with the key fob are ok, only without beep signal.
When starting the car, the red LED begins to glow after 3 seconds.
Cutting the battery starts the alarm with sirene.
Jacking the secured car have also activated the alarm but without sirene, only the indicator lights.
Driving about 60 Km yesterday was without a sesult.

Now i followed Stefano's (maranello72) advice and checked the small cable from the battery, followed the cable to the sirene.
There is a plug before the sirene, there are 3 more cables (red, yellow and black), coming from another place, going into this plug.
I saw that the black one is broken.

Perhaps, when i changed the engine mounts, i pushed a hydraulic tube from the power steering to the top in this direction, so it's possible that i damaged this cable.
I will fix it the next days, lets see what happen.

Thanks to all.

Daniel

 

Daniel,

don't fix that!!!
The broken black cable was removed from the plug (which is meant to take only 3 cables - positive, negative, serial communication) when the bypass cable to the main battery was fitted, this is normal.

If you reconnect that cable to the siren, the cutoff switch will be useless as the negative will always be connected to the rest of the electrical system via the siren unit.

I understand your siren sounds as it should, but does not produce the short beeps upon locking/unlocking of the doors.
It seems that there is a problem with the antitheft control unit, and not the siren itself.

Stefano

 

Damn, this means that the problem is already there.
