Today my DCCD automatically switched from the AUTO setting (which i keep it on all the time) to the bottom green circle on the dccd setting display on the gauge cluster. I read in the manual that when the green light flashes that the center diff is unable to be controlled manually or automatically and it defaults to 50/50. A day before this happened my ABS light came on????? Has this happened to anybody before........does the ABS have ANYTHING to do with the DCCD malfunctioning? I have an appt. with PRECISION TUNING (in Brick, NJ) to see if they have any info on this before i strip the car back to stock to take it in for a warranty fix. Any help on this matter would be greatly appreciated! :confused: :)

I know the DCCD controler has a "limp" mode which is exactly what you described. The DCCD uses a signal from the ABS system. Since the ABS light came on first, the ABS system may be the cause and that's where I would look first. Check the obvious things like the ABS fuse and brake fluid level.

You could have popped an ABS fuse. More than likely it's a wheel speed sensor.

Dirty/broken/or out of adjustment wheel speed sensor. Should be easy fix.

Old bump...how do you diagnose/repair wheel speed sensors? I know it would be simple to just throw 4 new ones on there, but I'd like a good explanation of how to find out which of the 4 is the culprit. Thanks,

drivers side rear wheel sensor goes bad or throws wrong signal, just replace both rears
