When replacing the rack, the steering wheel needs to be tied in place and not let it turn.
You have DSTC. The ABS needs to know the position of the steering wheel at all times for
stability control. The steering angle sensor module, forward of the steering wheel, uses an internal ribbon
cable to let the steering wheel turn full lock left/right. When the column joint was removed and if the steering
wheel turned and not locked down, it will be one full turn off. This can break the internal ribbon cable.
The SAS, steering angle sensor has 3 turns left and right when centered. The internal ribbon cable may have
broken. 1st thing to try is, you have to connect to VIDA or an OBD reader that can calibrate the ABS steering
angle sensor and reset the angle sensor. It will reset the steering wheel to center in the ABS, DSTC system.
Now start the car and turn the steering wheel full lock left and right, if the ABS or DSTC message does not return
it should be OK.
If the reset does not work the ribbon cable may have broken. If yes, the only fix it to replace the
SAS and recalibrate. The SAS is plug and play no software is needed.
