Forscan disable double honk

[Loco Lobo]

I am new to the site and wish to find out how to disable the double honk on my 2013 Cmax SEL. I got forscan and the license and the odb2 connection but when I went in the the body module configuration the only thing I saw was TMPS choices.  Does someone have the information so I can use as built configuration?

 

Thank you

I believe you're going to want to look into the Central Configuration specific option. That's where a lot of BCM related functions are stored. You should be seeing a LOT more there than just TPMS options. If you still only see those, check if there's a dropdown on that screen for different modes like 'engineering mode' or similar. It's been a while since I've messed with these options but in some programming areas of Forscan you have to make that change to see more stuff.

I tried that but still cannot get views of anything more that tpms options.  I also tried to look at the bcm on my 2013 fiesta and could only see the truck remote unlock.

 

But if I choose the as built configuration I see plenty but, I don't know the address and values to disable the double honk. Does anyone out there know which address and values I need to change to disable the double honk on my 2013 Cmax sel?

Unfortunately the BCM AsBuilt options are not well documented if at all for the C-Max, probably because the Central Configuration is the primary and preferred way to update these settings.

 

I'll check on my own later today after work and see if I can provide more accurate information. I also have a 2013 Energi SEL The modules are the same with the hybrid models.

I was thinking that instead of using forscan to disable the double honk (I don't have the ability to do so now) I checked the wiring diagram hoping that the BCM wiring could be cut out. But NO the steering wheel contact goes through the clock spring then into the BCM which then goes through the horn relay. So that isn't going to work. Page 44-1 of the wiring diagram book. 

 

Darn.  So far the only ways for me to eliminate the double honk is to either unplug the horns or pull fuse 20 15 amp from the BJB under the hood.  Of course if I do so then I have NO horns at all.
