Need help ASAP. I was driving and all of a sudden SH-AWD,ABS and VSA lights came on... I read on another thread this happen to others and the fix was a lose cable or dirty MAF sensor. So I cleaned the MAF sensor and reset the ECU by disco neg 1st and then pos. wires from battery. waited several minutes connected everything back but still getting all the lights. EVEN THE HORN STOP WORKING! and it won't come off PARK.

Got it off parking by pressing the button under the shift drove it back home from work and got brake system error forgot the exact message. I think it may be the ABS sensor or so I hop.. HORN still does not work.. can it be a fuse ?

FIXED!!!!!!!
I feel a little embarrassed but need to share just in case it happens to others!!!
I was STOP/HORN fuse!!! it was blown. THis cuased all the lights to go on, not allow the car to get off PARKING, and was giving me brake system failure message!. Unbelievable.
Hope this helps others who experience the same issue as this fix will SAVE you over 120.00 which is the amount quoted to me by ACura dealer when I called them.

Wait, there is a fuse to stop the horn?

The stop and horn Fuse in the fuse box... I forgot the number but its one fuse that is assigned for Stop/Horn...

zerogravity

Stop as in break lights.

if that fuse goes off the ECu detects brake failure and the VSA, SH-AWD, ABS lights go on.

Now you have to wonder what popped the fuse?

How many amp?

Look for an intermitent short?

Good info, thanks for sharing.

Get spare fuses for the future fails until you find the source.

Well I been driving all day and thanks God nothing has gone wrong I don't think there is anything wrong with it as this just happen to me for the 1st time in 3 years of ownership. I do honk the horn a lot especially at Cab drivers LOL may that was the issue that cause the fuse to blow.

Having the same problem here. The horn causes the fuse to blow once in awhile. Last time was a month ago. Did it happen again after you replaced the fuse?

I had the exact same problem last night and thanks to this thread, the car is back up and running without an expensive dealer visit. Pretty bad design- one fuse can knock out the major safety systems.
Not sure why the horn fuse blew but it went while I was using it. Bad ground?
Did anyone ever figure out what caused it to go?

Update it hasnt happened again
