Hi All, I am hoping someone can help me with my Skyline GT250 2005. I had a flat battery failure and tried to jump start but failed because probably battery had died. I then connected another spare battery but mistakenly connected the wires incorrectly. Since then, it seems the electrical system is not working at all. Headlights, Immobiliser, Ignition nothing works. I called Racv and they replaced the battery thinking the battery was really flat but no luck. Can anyone please help me how I can fix it? Thanks

It could be the the fuses found in the IPDM relay box behind the battery, the 100A fuses found on the positive cable/terminal of the battery or your BCM being fried. Try checking IPDM fuses and the relays, then check the fuses on the positive cable/terminal. BCM is about $400 delivered via Amayama (plus $100 labour for Nissan Ferntree Gully to install and program the BCM to your keys).

The 2.5L doesn't have NATS does it? I thought only the 3.5L needed NATS key programming...

Anyway, I suspect by now it's either fixed or burnt out down a dirt road. :P

2001 to 2002 do not require programming. Only 2003 and beyond require NATS key programming. :)

    • If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
    • Lock me in mate, although I'm not sure if I'll be heading up from Goulburn or down from Sydney, either way, return will be back to Goulburn 
    • Sounds good, we will aim to be there! @The Bogan I'll give you a shout if you are heading up to campbelltown for the meet too.
    • Before I get to the test day, just to finish off the android head unit. This is a demo from car start up....the standard/host system takes a few seconds to boot (same as all v37) but Android comes up quickly. In this vid I'm using the delivered launcher but have set the default to Agami since which is easier to navigate when if use primarily 5 apps. You can see the host system still takes over when required eg putting it in reverse, and you can switch between Android and not by holding the back button 3 sec. It is pretty responsive (fast) but you can see I had to press harder than expected a couple of times.  I still have the phone connected to the stock system, and that also seamlessly takes over Android music playing. v37-android-demo.mp4 The bigger reason that I put this in though is so that I can use Ecutek directly on the head unit. That gives me a dash with logging (up to 20MB only), high and low value warnings on any parameter etc etc. I've run a USB cable from the Ecutek OBD dongle to a USB input on the unit, easy. v37-ecutek-demo.mp4   The unit did freeze on the launcher the other day, I think Agami was trying to verify the license when it didn't have a data connection...will monitor and report back if there are any other problems but so far I'm very happy with the upgrade.
    • Nah that is just crappy GPS mapping, I did have a small excursion (cold tyres, damp track, surprise!), will post up that when I get a chance.
