2005 DB9 a few question

[mike-2txrc]

Evening, just wondering if you could help as I have a few questions.

Does the 2005 DB9 have adaptive steering as it seems to go heavy whilst driving but light when parking etc?

Does the 2005 stereo have Bluetooth phone capability as I pressed the phone button and it said fit SIM card???

Battery change, if I change it does it lose a load of settings? If so is there a way to keep to power on whilst changing the batt?

Thanks in advance.

Can't help on the steering question but I suspect not.

• Bluetooth - It's an option... IIRC if it's fitted, there will be a blue light / logo at the bottom of the waterfall.
• SIM - The phone integration lets you pop a SIM into the dash. Section 9 of the manual covers it. - https://db9s.com/db9-manuals-and-brochures/
• Battery & settings... Yep, I suspect so.

Just from my previous ownership of a later DB9
Blue tooth most likely not however I used a Bovee 1000 ( ebay) which worked with my iphone so I could play Spotify through the system.
I am not sure about the adaptive steering.

Yes, the DB9 has speed sensitive servotronic power steering.

After the battery is disconnected the seats and the windows need recalibrating, but only takes a minute.
(Whoops, forgot about the misfire learning, haven't changed my battery for a few years)

Noted... Ta.

FWIW - Mine had battery problems but annoyingly the recalibration routine didn't sort the rear windows (Volante). It has also lost its BlueTooth configuration (I can operate via the steering controls but I'm unable to change the settings).

What year DB9 and what was the issue with the rear windows?

Most importantly the misfire correction factors have to be re-learned.

Yes; the finest piece of poor design you're every likely to meet and incredibly difficult/dangerous to reset.

As for bluetooth, if fitted there's a blue LED at the base of the waterfall as mentioned before. My 2007 car has it.

You can try replacing the battery without losing the adaptation. You need to take the battery and connect it with wires to the terminal under the hood. Then replace the old battery with new ones in the cabin. Then remove the clamps of the temporary battery under the hood. I did this on a Range Rover.

My Rapide went completely flat/dead. I had to pull fuses to get the windows/seats/door locks working again. I've driven the far at least 500 miles since then. I had no idea about this procedure. What does it entail?

2006... The window had gone down and stayed down. I'm not sure of all the steps leading up to it, as it happened prior to me purchasing at auction, though there was significant evidence of previous battery issues and other 'fiddling' in that area.

I tried the window reset procedure and applied similar principles to the roof switch, without success. I fixed it by grounding out the relevant connections on the connector block, to operate the window manually. I left it in the fully 'up' position, from where it has been happy ever since.

In the past I've read that you do five rundowns from 70mph without touching the brake, a/c off, don't touch anything until it gets to 20mph - which takes miles. I've tried it on the A12, being the only place round here with a decent run, and it's fking lethal.

I also just found this, which seems safer:

Either way you'll need AMDS or a Foxwell with appropriate software to know if it's learned them. It's absolutely bonkers.

Yeah the rundown procedure is ridiculous, i've never had this with any other car i've owned.

But please bear in mind AM had to include this into the cars because of government legislation, and very importantly if the car has completed it or NOT the engine does not operate any differently, all the rundown procedure does is to enable an algorithm inside the ECU to trigger a dash warning to the driver if a severe misfire is happening.

I would still recommend enabling the system, this would protect the engine and the primary cats. Preventative maintenance is to look at the misfire monitor at service every year plus replace the plugs and coils every 5 years.

[Blitzuk]

Thank you for the additional information. That whole process seems obscene and sodding dangerous. I'll have to look at attempting it down a very long and quiet road at night!

'will not lose their misfire correction factors if... the PCM has lost its 'Keep Alive Memory'...

That doesn't make sense to me. Don't they mean 'WILL lose their misfire correction factors if... the PCM has lost its 'Keep Alive Memory'?

It seems to me that they are saying the two memory functions are no longer mutually-dependant, so a car after those in the table will not lose its misfire correction even if the PCM has been reprogrammed or has lost its "Keep Alive Memory". Just got to hope the notoriously inaccurate AML Tech Pubs got this right

[Emilio Largo]

Correct.

The question to me remains where exactly in the car or in which component this data keeps being stored even if the "Keep Alive Memory" of the PCM is lost due to battery change.
