The Actron cleared everything that it detected, including the U1000. As soon as I fired the truck back up the ABS, TC, and Parking Brake light all came back on and U1000 reappeared as a 'current' code.

There's nothing different in the way it drives...I just have no ABS nor can I switch 4WD modes. Other than that it runs normal. No 'reduced power', no 'service 4WD' indicators...nothing but these stinking lights.

I believe the Tech2 is better equipped to troubleshoot the problem based on the live data readings from the bus...or lack there of from a specific module.

I wasn't in the mood to fiddle with it today...instead I chose to honor MLK by planting my ass on the couch and playing XBOX.

Any luck figuring this out? I have the same TC and ABS lights on and no switching into 4H or 4L.
