Windows & Locks non functional after flat battery

[Sir.Rothschild]

Hello All,

I have a V12 Vantage. I allowed the battery to go dead (forgot to plug it into the charger) after a few weeks of nonuse. I jumped it yesterday, jumped it, and was greeted with the "alarm system service required" error message which has since cleared itself and gone away. However, my windows are still not functioning (won't roll up or down) and the lock/unlock no longer works.

Does anyone know how I go about repairing this?

If it's anything like a DB9, you can reset the window modules by pulling the relevant fuse/s out for a few seconds. It got one of my windows going again.

Hello All,

I did the fuse trick (i.e., pulled fuse F82 and F83) which resolved the window issue and the locking/unlocking issue. However, now my gauge cluster has gone dark and is nonresponsive. Does anyone have any idea how to solve this? Is there a fuse for the gauge cluster that I could pull to reset it (what number)?

Any help would be really appreciated!

I would start with a disconnect and reconnect of the main battery. As you had voltages low below the 12 Volt, the ECus could go into a non functional state. With a disconnect of the main battery they restart. Like the one you've done with the fuses for the windows and seasts.

Are you sure your battery is now good? If the battery is on its last legs then a total discharge could push it over the edge, and we know how much VH Astons hate low battery voltage. How old is it?

My advice would be to get the tracker module checked first of all to see if that’s ok and wasn’t partly the cause of the drain. If that’s fine, just go and fit a brand new battery. As LTP says electrical gremlins are very common when the voltage drops, and a fully discharged (probably old too) battery will continue to prove troublesome. Hopefully an easy fix for you. BRM.

Replacing the battery sounds wise. I'll do that as a precaution. Is there any special procedure I need to follow when changing the battery? Leave it on the trickle charger?

Not being pedantic, but there’s a difference between a trickle charger and a battery conditioner. You probably meant a battery conditioner, which are “smart” and will cycle the battery once it’s fully charged, rather than a trickle charger just continually trying to stuff a few extra amps in. Continually having an actual trickle charger connected to a battery will not do it any good.

But yes, I had a new battery on my Vantage in September as a precaution and it lives connected to my Ampmatic battery conditioner, unless I’m driving it

Do we bother with engine misfire corrections after disconnecting the battery? They are extremely tricky to put back.

And if your door mirrors autofold, that function will be lost and needs AMDS to reset. I am extremely careful not to disconnect my battery and warn garages not to unless essential.

These are just wife's tale, yes the misfire has to be relearned but that takes a 10 min drive to do and if your car had auto fold mirror that is written in the ECU so it wouldn't erase. I unplug my batterie every winter for 5-6 months for the past 8 yrs and yes when I plug it back in there are some gremlins I have to deal with but I never had to go to a dealership to fix those (window reset, seats reset, door module reset) they can all be done with the removal of the correct fuses. The main reason as to why we have those issues is because when the power is restored some modules don't at the correct time so by removing the fuses you restart them. Yes it is an 2009 Aston Martin Vantage but when you look at the system, it is just another V8 manual car in my case which I will never sell.

1) You're talking about a V8, not a V12.

2) The moment I disconnected the battery the autofold failed. Both my local autoelectrics expert and Nicholas Mee tell me it needs AMDS (which is why the former couldn't reset it).

I don't know how could this be possible but if you say so, I don't have a V12 or automatic folding mirrors so I wouldn't know.

I believe early Vantages (and I assume other VH models) required the the option to fold mirrors on locking was configured by a dealer using AMDS. Later models like mine have an option in the car configuration set-up menu that allows the owner to set this up themselves. I'm guessing, but could imagine that if it's a dealer-configured option and you disconnect the battery the controlling ECU could reset to standard.

My 2007 V8V doesn't have an in-car option to set mirrors - it requires AMDS
