checking out ABS

[sgopus]

Actually I'm haveing an issue with a smarty programmer not able to speak with my ABS to allow programming for larger tires, the ABS seems to be wolrking ok, no lights staying on ie ABS/Brake they go off when they should.
However my smarty programmer s3 will not communicatge with my ABS, it gives a communication error, techs at smarty say check the ABS, any suggestions, seems to me everything is working just fine, could it be a bad connection with the ABS computer, not the rear sensor???

ABS isn't what is adjusted for larger tires. Your tire adjustment is in the speedometer/speedo gear. Dealer can also adjust what's called the "pinion factor" in later model trucks (98+ with the sensor in the rear axle).

Myself, i run SCT custom programming with a SuperChips handheld on top for the tire adjustment.
