Had to replace my timing chain tensioner so I also replaced my front seal water pump belt and belt tensioner. Well after doing all this I put my battery back in which had been disconnected for about 3or4 days and everything seemed fine but my horn no longer works and I had an airbag error message on my system briefly but went away. Then my trunk stopped Poppin open even though the relay clicks, my horn still not working and I'm throwing a p0010 code now as well. I've checked all my fuses unless there's more I'm not aware of. Oh and then today my tire sensor monitoring system is giving me an error message too. What's going on? This has been a great car but electrical has got me absolutely stumped. Any ideas would be helpful-thanks.
