If there are only zeros in lines 5-18:
Check the MVB for -J428- misalignment angle. Ensure the angle is within specification (-0.8° to +0.8°). If it is
not, perform a calibration of the -J428-. 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,
AW 8B - Distance Control Module 2/Adaptive Cruise Control 2, and AW A5 Front Sensors Driver Assistance
System (some vehicle may not have all modules installed). With O.D.I.S. on the OBD screen, click on each
module one at a time, use the dropdown box just above the module list, and select MVB and then green
forward arrow. Display all MVB information for that selected module, then on the right side menu of O.D.I.S.,
there is "OBD Log", select this, then select "New", then "Add", then "Display". This will then open a HTM file
that can be saved to the laptop. Do this for each of the modules requested.
Conduct a visual inspection of the radar sensor(s) and driver assistance camera, their mounting brackets, and
glass. Note any signs of damage or distortion. Verify the sensors are properly secured in the mounting
brackets. Note if there is any damage or obstruction to the glass in the front camera location, if equipped.
Inspect the front bumper cover and grille for damage, distortion, or looseness. Take pictures of any findings.
Have the customer complete the Front Assist Questionnaire, as thoroughly as possible. The questionnaire can
be found on Service Net under Technician References, Technician Helpline, Worksheets/Check Sheets.
Once all information is compiled, create a VTA case. Attach the GFF log (with -J428- test plan data), all
MVBs, the completed Front Assist Questionnaire, and any pictures.
