So, if I understand you correctly -- you put your fob under the floor mat for a week and then placed the fob on your person (probably in your pocket) for a few weeks and that seems to have corrected the problem ? Perhaps you are on to something. Maybe a few more people who are having BCM issues will try what you did and we shall see if indeed this is working. Will look forward to see some responses -- be they positive or negative.
I have no idea if it helped, from what I'm seeing the BCM is giving everyone diff issues, mine is that the car always needs to see it. if i lock the doors and walk away the panic alarm goes off disables the fob to open the door giving i cannot see fob error & all my dash l lights are on with a 0 on the odometer. if i leave the car unlocked & walk away with fob i come back later & same thing as above except no alarm as the car was unlocked just dash lights and errors. i said screw it hopefully this will get stolen & just left the fob under the matt for little over a week & everything was fine with the car unlocked & fob under matt. now its been over a week & i stopped doing it & everything has been fine. I will let you know if it starts up again. parts are on order & will prob take months. just cant believe a Honda of all brands would crap out on me, been driving them since 91 & have had 8 of them between my wife & i since & this is the worst situation i have been put in, think i'll try Toyota on my next car. I also want to mention going everywhere & disconnecting the battery to prevent this cannot be good. im still hearing an arc when i connect the negative back on.
