Diagnostic Service 14. No additional action is needed.

1. Check if module is blocked (maybe cable is inhibited), try to release to release it.

2. Perform reference run, use the “Move x Satellite motor” routine to find a block point by moving the  motors to left/right limits and back to zero position and than check if the new Zero position is identical to the initial one , if module moveable and error still present  stepper motor is defect.
