Battery flat help .

[slim]

Just got a bit of a dumb question , but iv never changed a battery in a later model commodore , my 2006 vz seems to have a flat battery this morning , Can you simply pull it out and replace it like an old car without buggering up the computer , Or do you have to do it some other way , Gota get cracking ASAP . Any advice appreciated . Cheers Slim

If you do it quickly, the radio should be ok.

Radio pin is in the book in the glovebox or call Holden as you are registered owner.

insert a plug into the cigarette lighter socket with a 9 volt battery connected to it that will save the memory while the battery is removed and replaced little trick us autosparky use  Mickrat

In some late model cars, the engine management system controls the alternator output (Audi amongst others) so if the battery is dead flat, or you disconnect it, you need to tell it what type of battery it is before it will go.  This requires plugging it in and and communicating with a gadget you probably have, so when in doubt use a memory minder (goes in cig lighter with a 9v battery) or get cunning with jumper leads! And save yourself some drama!  This kind of set up is becoming increasingly more popular with manufacturers as they look to improve economy and emissions,  system voltage effects how long it takes injectors to open, earlier EFI systems monitor voltage for that reason but they have found it better if the ECU controls it.
Goodluck
