G35 MT6 Coupe
Horn/alarm issues

I posted this in another thread but I'm new here and want to make sure I'm doing this right so I'm posting it here too. I have a 2004 G35 MT6 and when I try to set my alarm the horn blows constantly and the key fob will not shut it off. I have to use the key fob to unlock and then start the car toy get the horn to stop. This happened 4 times yesterday and now this morning I came out to go to work and the car is completely dead, it wouldn't even jump start. I have a new battery so I know that's not the problem...any ideas?

Has this vehicle ever been involved in a flood?
Bad ground/poor battery cable connections/corrosion?
Defective IPDM?

Grab your multimeter and follow the steps on SC page 9
