I'm curious on how they figured out the CAN bus code to chirp the horn if the
PIWIS couldn't chirp it. Does the horn switch on the steering wheel activate the horn over the CAN bus? Otherwise I can see how they captured the code.

Remember you can always enable/disable the Mods4Car module so that a dealership cannot even tell it is there and basically it isn't, it is listening on the CAN BUS but not replying so it isn't doing anything unless it gets the signal to wake up and go active again. Right now Mods4Cars is running a group buy, a good time to pick up their module. |
