I think that you mean DAST module. If the car was wrecked, I would make sure the front wheel speeds are reading correctly and I would bet that you need to calibrate (re-zero) the steering angle sensor.
You do this by performing DAST calibration mode 1.
There has to be a code in the DAST system. Find what that code is. C1138 in the brake module simply means that there is a fault in the DAST system.
