I've got the weak horn bushing issues going on and was wondering if disconnecting the bat before I get into the airbag area will I cause some other random issue, i.e. security codes for radio, sunroof memory, rear main seal squirting, IMS jumping out, pistons slamming into valves, coolant bottles exploding, oil and coolant swapping paths, pass window falling into door....etc. I'm kinda joking about all that but then again the F150 in the driveway (that never breaks) would never let me forget it if it happened. Is the disconnect neccessary? Seems like it could get violent if the airbag were to get shorted.
Thanks

what car (year)
new are differant than old -
Also this gaget saves you from any troubles
"
Automotive computer memory retaining tool designed to maintain the memory of the on-board vehicle computer (CCU) when the power source (battery) is disconnected. Use of this tool when changing or interrupting the power source prevents loss of certain driveability codes, keyless entry codes, digital radio setting, cellular phone settings and other memory related functions. Prevents loss of radio function on anti-theft radio systems.
Use with 9 volt alkaline battery "
available at many local auto parts stores or on-line under $10

I didn't have any issues on my MY99 when disconnecting the battery when I swapped steering wheels. The only thing I had to do was re-enter my radio code and re learn the windows (Cycle them up and down fully) so they would do the auto lower when I opened and closed the door.

Yeah, I've had to disconnect the battery on mine several times, and I've never had a big problem. Most that I noticed was that , like LJPete said, the auto windows took a cycle or two to relearn the one touch feature but everything else was good to go

One other thing to consider is that the emission codes will revert to a "not ready" state if the battery is disconnected. I made the mistake of replacing my battery just before taking the car in for inspection, and it failed the ready test. I had to drive it for a few days and then take it back to get a passing grade.

Radio codes if needed can be obtained before disconnecting battery.
Ecu will relearn fast enough once battery reconnected and car driven.
Seat memories and window positions and what not will have to be reset.
Much less trouble though than dealing with after effects of having an air bag go off in your face while you are removing steering wheel. If passenger side air bag triggers it can destroy dash. This is approx. a $2000 part and labor to replace is not cheap.
Sincerely,
Macster.
