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.
