Hello Honda Fit People - can anyone help me?
I left my overhead light on overnight and drained the battery. It's a new battery so it shouldn't be forever dead, just out of juice. My husband and I tried to jump it - it initially started, but then didn't start again after I shut it off. When we tried to jump it again, the security system engaged (horn and lights blinking) and I tried to disarm it by pressing the unlock button on my remote key (like the manual says to do). It didn't work. We disconnected the cables and tried again. This time the horn just continually honked (not the usual rhythmic succession of honks with flashing lights) and wouldn't stop until we disconnected power. This continued after I tried locking and unlocking the car with both remote keys to try to disengage the alarm system. Finally, my husband just pulled out the relay he thought was connected to the horn so we could try jumping it without the loud honking bothering the neighbors at night. It stopped the honking, but this time my car wouldn't start or even show any sign that power was coming through - turning the ignition did nothing, even after several minutes of connection to his car's engine. We could hear some kind of humming inside the my engine when the cables were attached, so it seems like there was power coming through (so the connection was good), but nothing would happen when I turned the key...

So, then my husband replaced the horn relay and tried jumping it again, and the battery fuse blew. He replaced that and jumped it again, and my car started, but we couldn't get it to move out of park. He assumed it must have been the car's Immobilizer System, but the Fit manual says that that would keep the engine from starting at all. He tried it again and the engine isn't starting, so we don't know if it's the fuse again or the security system or what...

Before I call the dealership and try to explain all this to them (badly) over the phone...does anyone have any ideas?

Thanks,
Amanda

 

hey Amanda similar situation for my 2012 Honda fit sport left the indoor lights on overhead drained the battery jumpstarted it and the alarm system flashing lights and horn all started going berserk. I finally got the car to start but the alarm system lights in horn wouldn’t go out, and after I jumpstarted a few times to gently recharge the battery a little bit at a time I did get the car to start, but the alarm system wouldn’t accept my key to turn off the alarm and just go back to normal as a reset what I tried was to disconnect the fuse that goes to the horn and it worked beautiful. The only problem was I couldn’t get the car into gear and the interior lights still didn’t work, and my remote entry function was dead. The only way to get the car into gear was to put the shoes back in to where the porn relay was then I tried driving the car down a quiet street with no houses after starting it and I’d have to say maybe about a quarter mile later. The alarm system turned off and the car ran great and the horn didn’t go on anymore, but it does every time you restart it and put it without disconnecting the horn relay so I’ve got something now to check each and every fuse to see if any fuses are blown luckily I have a nice tester and I’ll just go through everything inside the fuse panel and in the engine compartment shoe panel and hopefully I’ll find a fuse that blue and I’ll be OK. Let me know what your outcome was. Did you ever get it fixed or did you sell the car
