I slide on the leaves and ABS tries to kick in. Pedal goes to the floor, no pulsing, and I get no brakes. Brake and ABS warning lights come on and stay on. Brakes come back under normal operation. I try to engage ABS again and pedal goes to floor, no brake pressure. I've got full fluid in my master cylinder (though it's dirty) with no leaks, all vacuum lines are attached. Any ideas? This may be the first time I've ever engaged ABS on my truck. I can't remember ever doing it before. I'll pull the codes when I get home. 4   L A T E S T    R E P L I E S    (Newest First) Roland Posted - October 19 2007 : 07:04:25 AM hey Peter; For what it's worth, I suggest disconnecting the wiring which will dissable the ABS. Brakes still working normally and ALWAYS. Many locals have had accidents or near accidents (myself) when the ABS was connected but would not work. Uneven, washboard roads, gravel, water, snow... anything but hard dry pavement can cause ABS to fail. I yanked it completely on the Sy, and have it disconnected on the Ty. NO brake issues on either since. With connected, it will happen again. Paul Posted - October 16 2007 : 11:04:27 PM I think I have another ABS just sitting around if you want to try it.

GMCTurbo Posted - October 16 2007 : 2:39:35 PM Just found this article... http://www.asashop.org/autoinc/aug2000/techtips.htm internet self help is great isn't it? :-) GMCTurbo Posted - October 16 2007 : 2:36:46 PM So I figured I'd pull the code now while it's still light out. It's throwing a code 62... <i> Code 41 through 66 4WAL control unit or motor circuit Check for a loose ground connection at the motor circuit. Clear the code and drive the vehicle. If any of these codes return, the EHCU valve may be faulty. </i> I don't seem to have any loose grounds and I pulled and reconnected all wiring to the ABS units so I'll see if I can reproduce on my way home.
