WOW! I was just about to post the same thread!!
This happened to me last month with that HUGE ice/snow storm in the midwest. At home, we had 8 in of snow, followed by 1.25 in of ice, than another 4 in of snow on top of the ice. REAL nasty!
I pulled into the snow/ice covered entrance to my storage unit (where I keep my classic cars) to steal the batteries out of my cars to use on an inverter. My electricity had gone out and I had to figure a way to keep the sump pump going... Well the dive is steep and it is lower than street level, about 150 ft in length.
I pull up to the gate, and the gate won't open because it it iced shut. Realizing that I had forgotten the keys to my lock, I start to back up out of the drive.
I was spinning the wheels, and then got stuck on the snow bank of the pile of snow the plow driver left at the drive. While spinning, the ABS light came on and stayed lit.
Just a note, no amount of cursing will cause the light to turn off...
I was mostly mad, because I was getting ready to make a trip to Louisville to pick up my brother at the airport and ABS is kind-of needed on slick, icy roads.
After 4 ignition cycles, it turned off. Oddly enough, the 4th cycle is when I decided to plug in my scanner to find out what tripped it.
Does anyone have an idea what caused it to trip?
