3 channel = look on top of the red end pumpkin. That is where the sensor is located.

4 channel = on each axle hub.

check the sensors first. could be a cut harness or unplug.

Go to a parts store and let them plug in an ABS scanner to read the code. Other than that, a bad wheel sensor or damaged wire harness is the usual culprit.

Yeah its weird, right after the dyno tune it came on. The tuner said most cars don't like going 100+mph while stationary so it may have rumbled something lose. If we don't get rain I'll check there tomorrow. I pulled the plug at the main harness and everything looked ok.

Ok - you did not mention that. Disconnect the battery and clear the light and you may be good to go. The system sensed a fault as the front wheels were stationary while the rear was going 100 mph. My car did the same thing when I ran the car in the air to break in the new rear.

I'll give that a whirl.nnwhile I have your attention I did rear control arms and pan hard bar, adjustable on one end and bushing on the other. How much louder will it make the ride because I'm hearing them rattle ( or at least I think it's the rear control arms) even on the smoothest of roads. I torqued to 72ft/lb as Jim instructed and put about 2 to 3 pumps of grease in.

Mine has never made noise...

Maybe they've come loose. I'm gonna be replacing the shocks at the end of July so maybe that will clean it up a bit.

Probably something else rattling back there if the bolts are tight. Mine have never made a peep since installation. I would check the clearance between the exhaust and the body where it runs up over the rear axle.
