I have a 1999, and I have disconnected the battery a few times with no problem. From what I have read, the first time the radio is turned on, it registers itself with the ECU (or something), and no longer needs the code, unless you try to change the radio from another truck, or the ECU.

iirc the code is stored in the ecu i've disconnected mine a few times and had no problems with it re-registering when battery is re-connected

Its never crossed my mind, but i have disconected the battery a few times and never thought about the radio code, it just came back on...

We did have a problem with another one though, after we disconected the battery the key would not start the truck again and it had to be re-coded.

( I bet that made you feel a whole lot better

I fitted a new battery to my 2001 model and had no problem with the radio, I think I had to retune it, but that's all

I fitted a new battery to my 2002 model on Sunday,as said everything worked ok afterwards.

On my 1995 Maverick, which has a Ford radio, you need the radio code on battery disconnect, as there is no immobiliser system on the 2.7 td version.

changed my battery on my 2002 model, no need for a code (assuming you have the standard nissan radio fitted) as it will just need retuning again

I think i have a code breaker for ford radios somewhere

You can get round this by putting another smaller battery in parallel while you change the main one. david.
