traction control and 4wd on and flashing

After installing 4.56 gears and ARB front locker, the traction control and 4wd lights are on and flashing. What can be causing this? thx

Your system is disabled and cannot use those features. You need to do the YAW calibration tweak.

Could be several things... Did you hook the ADD harness back up properly.

Also, sounds like the old speed sensor wire problem. Very common for one to lose connectivity after any type of install. Test those with a multi meter.

Thanks for the quick replies. I forwarded them to my mechanic. I will report back. Thanks again
