Since I bought my truck a year ago, the ABS and VSC/TRAC lights have been on. I recently found that there was a break in the harness for the front left wheel speed sensor and repaired it, so that those systems are functional again. ABS light and VSC/TRAC lights off, no error codes. However, now I hava a new related problem. The VSC/TRAC (I think more the VSC) is overactive. Especially taking off turning right, power is cut, brakes applied, and a loud pulsation. Taking off straight or turning left sometimes results in mild symptoms. Once up to speed, no troubles at all.

I've tried (twice) the zero point calibration and decel sensor calibration. It seems to have helped a hint, but didn't fix the issue. I need help! Where to look next?
