Note:
For display group number 002 remember:
The reading of measured value blocks in display group number 002 must be undertaken when
driving off slowly. Then the ABS Control Module (w/EDL) -J104- will store the first usable
voltage signals provided by the speed sensors and display these as a fixed value in the
measured value block.
