"Hello All",

I know that the subject of the Xtrail Battery has been discussed before - including a thread posted previously by Me - But I was directed to a Video about Battery changing where before disconnecting the existing Battery you are told to `Lock the Doors and take the Keys away from the vehicle` - words to that effect.

I think that it is mentioned that this is to prevent any problem with the Immobiliser / Keys / Fobs when the New Battery is connected - I hope that I will be able to simply open the Door after fitting the New Battery.


There is also a procedure to follow when the New Battery has been fitted regarding NOT Starting the Vehicle - but turning the Key to `On` and leaving it for 2 Minutes - I am guessing that this is so that the ECU is Reset - ?

It is many Years since I fitted a Car Battery and I don`t remember having to go through ANY procedures such as these.

So that I don`t have to note the exact wording and Type it here the Video`s for `Removing a Car Battery` - and a seperate one for `Fitting a Car Battery` are here:

http://www.youtube.com/watch?feature=pl ... 7L074W5YfY

http://www.youtube.com/watch?feature=pl ... 0YcY_iWTig


The Video`s are from the AA - on the `Honest John` Driving website so they are definitely `legitimate` / `Safe` to view.

I know that I will now have to take notice of these details - But can any Members comment whether they have carried out these procedures when changing an Xtrail Battery - ?


Regards,

Chris

Hi Chris, when I changed my battery I never did anything different to when I had any other car. My car is a 52 plate T30 deisel. Everything worked ok afterwards. One note though, is your radio key coded and if it is do you have the code. Mine is the original radio/CD changer and does NOT have a code. Personally I would NOT lock the doors or at the least leave a window open incase you need to get into the car for some reason things dont work.

Mines a T31 with keyless entry.
I charge my battery regularly and have been disconnecting it from the car first until now since I have bought a CTEK. Before disconnecting I attached a second battery in parallel to maintain memories. Once however I got it wrong and the car was without battery power for about 2 hours. I had no problems other than I lost my radio presets and the auto function on the drivers window had to be reset.
Locking the car before changing seems very odd.

"Hello All",

Thanks very much for the messages - I am now reassured that I do NOT have to do what I asked about in My original message - regarding the AA Advice in those Video`s.

I also have never had to carry out the `Lock the Doors before disconnecting the Battery` process - AND it seems a ridiculous thing to do to Me !

Although you could probably still open the Driver`s Door on My Xtrail just using the Key in the Lock [only keyhole on My Model] I cannot see any advantage of doing this `Lock the Doors` process - ?

I can only assume that the AA Patrolman / AA Technical Department know of some Cars where this HAS to be done and because they cannot see any disadvantages of doing it to all Cars [?] have included that process in the advice on the Video [?].

Also in the Video for fitting the New Battery - after connecting the New Battery it is stated to firstly `Lock and Unlock the Doors` using the Remote / Keyfob - I wonder if this is because you have been advised to have Locked the Doors before removing the Old Battery - ?

I am slightly confused about that point because the next Important detail is to `Turn ON the Ignition - BUT - NOT Start the Car` - this is obviously to allow the ECU to Reset - obviously from Members messages there is no `Reset process` after a Battery change / disconnection regarding the Immobiliser / Keys - ?


In the past I think that I have seen a reference to `Must have the TWO Keys / Fobs TOGETHER in the Car` - regarding the Immobiliser recognising the Keys after a particular process that I think involved the Immobiliser and Keys `Pairing` - I take it that this was something like getting the Immobiliser / Starting system to Re-recognise the Keys / Fobs - ?


I did previously wonder whether changing / disconnecting the Battery would cause ANY process to have to be done regarding the Immobiliser and Keys / Locking system ?

As I mentioned above I am very grateful for the replies and although I made the comments above wondering about the `Advice` from the AA I will now be replacing My Xtrail`s Battery as I would have done before the AA Video`s were brought to My notice.

The Video`s were mentioned to Me by a Friend who I had told that I was going to fit a New Battery to My Xtrail.

He stated that I should check out these Video`s as Battery changing seems to have become more complicated than it was previously - and that He did not want Me to get into a situation where there was a problem with either the Immobiliser / Keys & Locking System or the ECU Reset.



"Thanks again Gentlemen".

Regards,

Chris

P.S: raccoon - Thanks for mentioning the Radio Code - I do have this - obtained from Nissan - but I appreciate the reminder.
