Loose Gnd?
Long cruise. On the way home a grp of bikers came by and waved, I
was going to toot the horn and wave back, but NO HORN!!!
Earlier in the trip I got a service soon msg for the active handling/
traction control. I reset the warning.
At the next stop after the bikers I got a cup of Joe, restarted the car and the horn worked just fine, and is still wkng now.
I suspect a loose grnd but am curious if pwr for the active handling/traction control may be on the same buss (wiring?) or a common grnd? Wish I had a schematic of the car....
