So first chance for my commander to see snow today not a lot. To check things out i gunned it from the stop sign no slipping nothing, slammed on the brakes and started to slide as excepted.

Now all my jeeps before where old school no fancy esp and traction control. As I slid my brake pedal pushed back at me and and pulsated and a clicking noise was present I am guessing this was the traction control? Just confirming this... I had no idea what to expect and honestly didn't realized it worked during braking as well.

It was probably your ABS if you were locked up while stopping. The clicking from traction control happens when you are moving through soft ground (sand) and I would assume ice and snow, but my XK has only seen soft sand. lol

That was your ABS.

ABS = Anti-lock Brake System, keeps wheels turning (pulsing) in front so you can steer , if wheels lock you can't steer in a slide. Watch the NASCAR guys - they lock the brakes all the time and can't steer when they spin, maybe they should install ABS or get their foot off the brake pedal once in a while.

ABS - BTW, What you feel is the sensor releasing the brake and then applying the brake over and over. Police used to disable it because they were used to pumping the brakes to stop to get the same effect but the two didn't mix well together. I have an relative that worked for UPS and they spent many many hours trying to figure out speed without the traditional skid marks when anti-locks were introduced.

Way more that what you asked - I'll stop now!

When the ABS activates, there is an electric pump in the module that takes over for you and pumps the brakes just the right amount to keep the wheels from locking up and gives the best braking for the shortest stopping distance. That feeds back into the pedal and makes the surging pedal and noise, just keep pressing the pedal, it means the system is working like it should.

Keep in mind, in snow, gravel and mud, you actually stop shorter if you lock the wheels at low speed, the ABS system is designed to recognize that and adjust accordingly. So if your wheels actually lock up when you get under 5 mph, that is likely the ABS working the way it should.

Jeep also uses the ABS to create a virtual Limited Slip Differential, when your driving, accelerating, etc, if a wheel slips on ice/mud/snow, etc with the open differentials, that should cause all the power to go to the slipping wheel and lose power to the wheels with traction and get you stuck. The ABS will activate to slow down the slipping wheel, and that redirects power back to the wheels with traction, and thus you don't get stuck. So, if you're driving in ice/mud/snow and hear noises from the clicking, pumping, etc, its just the ABS doing its job to keep traction and power to all the wheels. If your foot was on the brake during these operations (it would be on the accelerator) you'd feel the pedal surging.
