Default Help 03 WRX wont start after new battery!

Ok, so my buddy has an 03 wrx and recently the battery went on him so he got a new one put it in and now as soon as you connect it the horn goes on and just stays on. not intermittent just stays on unless you pull the fuse or relay. Also there is no power anywhere. no interior lights, nothing happens with the key no door locks, windows, no security light or gauges at all for that matter. Tried the key thing on and off 3 times with no luck and tried the keyless entry nothing will shut this horn off. I am going to go through the wiring diagrams myself to try and trace the source, but does anyone have experience with something like this. I really dont think its security related, but the car is completely dead. The only thing that works is the little switch on the steering column that turns the parking lights on


All fuses look good??

Been there, done that. It sucks!!! No store in the city of Cincinnati carries that fuse. The dealer didn't even have it. Had to order one. We bypassed it for a day or two with a piece of wire. Not the best idea for electrical safety, but we need to have the car running.

Sounds like a fuse but could also be the ground wire that runs off the negative. The battery will choke (like fry) when you turn the car over. If it is it is somthing is not grounding. Check the starter and make sure that's grounded. Get a tester and just run down the board. 40$ can save you 30 minutes of pulling fuses.

If the fan is coming on though...heh...might be ECU.

well nothing works at all, as soon as you connect the battery the horn just keeps blaring and wont stop and there are no interior lights, no ignition nothing. but if you flip the switch on the steering consol the parking lights come on. all the fuses are ok . I think it may actually be the security system, but I always thought the horn would go on and off. this just stays on and wont do anything else

sounds like it has/had an aftermarket security system. there is usually a "passcode" of things you have to do in the car to disable it.

Seems like basic trouble-shooting to me. I'm still thinking it sounds like the battery terminals are reversed. Did you actually look at the negative and positive signs on the battery? It's not uncommon to have batterys that look the same where the terminals are reversed. If you're positive, red's going to plus then it's probably time to break out the meter.

how would having reverse polarity cause the horn to stay on and nothing else to work besides the parking lights. I am really pretty certain that the battery is hooked up correct. at least now. My friend didnt tell me if he hooked it up backwards first.

As far as the security thing. its def not an aftermarket one, it has the factory keyless entry and when we called subaru they took the vin and said that it does have the factory alarm.

Now looking at the wiring diagrams, the security control module looks like it hits the interupt relay which would kill the ignition, also branches off to the illumintaion (maybe why I dont have any light?) and also has a horn trigger switch. so if this thing is fully switched it looks like it could be very possible its causing all my problems.

Now the only thing I am thinking is I tried the disable both with turning the key on and off 3 times and with the remote but nothing happens with either. do all the doors and hood need to be closed to disarm the thing? because when we hook the battery up we have been leaving the hood open, and I know for a fact my STi has a hood switch that will trigger the alarm and it will keep blaring untill the hood is closed.


I dont know, but we need to get this car moving again asap and realy dont want to tow it to subaru and pay a premium for their troubleshooting

Horns and light work whether the polarity is reversed or not. It's just DC to them, the direction doesn't matter. Everything else, the polarity has to be correct.

Like the poster above me said, how can you not be 100% sure? It's either installed right or not.

I am not 100% sure because its not my car, not at my house and I have to drive to go look at it. I didnt put the battery in my buddy did, so when I go back I will have to check it out. I didnt really think to look at that when I was there for the fact that I really didnt think anyone would ever mess something like that up, but I guess it is very well a possibility

I've seen people screw that up. Never underestimate someone's stupidity. If true, I'd blame the parts place more than your buddy. I assume he put the battery in and it was running before he did it? If not and someone else put it in and he was able to drive away then you know it's not the battery polarity.

The sequence of events is kind of missing.

If it wasn't running before the new battery then maybe the battery's a wild goose chase and something else was already messed up.

This may be a stupid question but is the new battery dead? I've had several cars that when the battery was literally at the brink of being out of juice it would just turn the horn on and nothing else.

I had this same problem.

Under the hood, you have a fuse box. In that fuse box is your MAIN FUSE and other important fuses.

Open that fuse box, and the only fuse that you cant PULL out is most likely the one thats burn. You need to loosen 2 hex nuts and itll lift out.

Replace that and youll be ok.


When I had this problem, I tried to jump the battery, when I did so, I accidentally switched positive and negative. As soon as I made contact the horn just went off and stayed on. I was bummed. I asked my cousin/mechanic. He knew right off the bat it was a main fuse. When I checked them it was clear which one was burnt. I replaced it at a local auto store, Autozone has it as well.

It can be a couple fuses that will set the horn off and keep your car from starting. Check them all.
