Wheel Speed Sensor, Checking

Wheel Speed Sensor, Checking

Display group 002
The measured value block for display group 002 must be read when the vehicle is being driven slowly. ABS Control Module J104 (w/EDL) 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 Scan Tool VAG1551 when the vehicle is being driven slowly.

- Press buttons 0, 0 and 2 to input display group number 2 "002".
- Press Q button to confirm input.

There are always 4 display fields - arrows - in the display group. Descriptions of the individual values in display fields 1 - 4 can be found in the table.

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 J104 (w/EDL) will store the first usable voltage signals provided by the speed sensors and display these as a fixed value in the measured value block.





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).
