If it is not:


Perform a calibration of the -J428-, and then refer the customer to the Owner’s Manual and
www.knowyourvw.com for an explanation of the system operation and limitations.

If there is any alphanumeric data in lines 5-18:
Gather MVB information (via guided functions) from AW 13 Distance Control module/Adaptive Cruise Control,
