DII Brake Question
It's been very cold here in Oklahoma City the past few days. The roads have been icy and it snowed here today. So the other morning around 6:30 AM I was driving down a city street and when I pressed down on my brake pedal my brakes locked up and I started to slide.....(I was on ice, NOT snow)
*Note: I did NOT panic and STOMP on the brake pedal. I applied my foot to the brake pedal as I normally do when I drive.
My question is: What is causing my brakes to lock up on iced over paved streets?
Any help/input would be greatly appreciated.
Thank you

All the lights come on on the instrument cluster when I turn the key to start the truck. I thought Spike meant, "Are the 3 Amigos illuminated when the vehicle is running".
But to answer your question, no....there are no lights that are constantly on and the lights have not been painted over.

What would happen if it was so icy all four tires locked up at the same time. I do not think the ABS would turn itself on because it does not have a tire spinning. As far as the computer is concerned the truck is completely stopped.

I have never had that happen in any vehicle I have ever driven with ABS on ice, but that does not mean it cant happen.
I suppose it all comes down to tires, how slick it was and how hard he was on the brake.
If its smooth sheet ice the slightest braking will lock up the wheels and I could see the ABS seeing that as completely stopped.
Now the question would be was the speedo at "0" when this happened?

I see where you are coming from and I understand what you are saying and I agree that is a very good possibility.

It's fairly routine to lock up all four on ice, especially so with a dry pavement tread design. If the entire roadway is icy, and if it has an even skiff of dry snow, antilock function is non-existent. I use Bridgestone Blizzaks in the North Dakota winter. They are very good on ice, in particular when extremely cold (20 - 35 below F) thanks to the extensive sipes and soft rubber. Even with those tires, if the traction is equally bad under all four, antilock will not work as no single wheel, or combination of wheels, will have significantly different rotational speed to trigger the antilock modulator.
