MEASURING VALUE BLOCK 1 

Checking wheel speed sensor 

Display group 002 

The measured value block for display group 002 must be read when the vehicle is being driven slowly. ABS 
control module (w/EDL) -J104- saves the first usable voltage signal from the wheel speed sensor and displays 
this value in the display group. The values are displayed on the VAG1551 when the vehicle is being driven 
slowly.

rotated by hand by a second technician).

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.

If the deviations in display fields 1-4 are greater than 6 km/h (4 mph), the following may be cause of 
the malfunction. Air gap between wheel speed sensor and rotor may be too large: Check that wheel 
speed sensor is screwed correctly to wheel bearing housing. Wheel speed sensor or rotor exterior 
damaged: Change damaged component.

NOTE:

For display group 002 remember: Deviations of the displayed values in display fields 1 - 4 must 
never be greater than 6 km/h (4 mph).
