Default BRANT Question

Hi All,

I am about to embark on an AV head unit install and will likely disconnect the battery when doing this as it needs to be hard wired in. (Cant find wiring harness for the kenwood AV style units)

Being a noob I am not entirely sure how the BRANT system works and how it is wired in but I do know it is an expensive exercise if it malfunctions.

So my question - if I disconnect the battery, will this reset or scramble the BRANT system in anyway that may cause me to not be able to start my car when i reconnect the battery?

Cheers
Matt

You will not need the master code to reset it (if required)...the reset procedure has been covered many times on this forum...just do a search.

Contact Subaru.

Or go buy a patch harness from Supercheap, unplug stock deck, plug in new deck and harness. Voilla, no need to chop up your wiring or disconnect the battery.

thanks Kato - I looked into this as it is the way I usually do it however no one carrys the harness for the new units (checked autopro/repco etc) as they include reverse camera and navigation options so there is heaps more pins than the plug on the kenwood patch harness.

Subaru don't usually give out master codes, things may have changed but I doubt it.

Ive unplugged my battery a few times now and never ever had an issue with the Brant... Im at a loss to see why everyone is so scared of it?

Early Brants will hold the code in backup for between a few hours and a few days but that's all. Brants from MY03 onwards have an upgraded backup battery and will (theoretically) hold your code for up to 3 months.

TMI on the brant Kato? I dont wanna provide opportunists with that sort of info i suppose...

Anyway thats Kinda scary to know about the Early BRANT's, thought the usercode would have been stored in some sort of non-volatile RAM memory rather than rely on battery backup to remember the code... thats pretty piss poor.
