Read Measuring Value Block (function
08)

The control module can transmit measured
values to the VAS5051 tester and VAG1551
Scan Tool (ST). These measured values provide
information about the operational status of the
system and the sensors connected to it. In many
cases the data supplied can be used to
troubleshoot and repair malfunctions. The
measured values provided by ESP are contained
in six display groups, which can be accessed via
their display group numbers.

- Connect the VAS5051 tester or VAG1551 Scan
Tool (ST) and select the address word 03 "Brake
Electronics".

Test table: display group 1
Notes:

Display fields 1 through 4 show the current wheel circumference speeds in km/h. These are calculated by the ABS control
module -J104- on the basis of the signals received from the wheel speed sensors. If one of the display fields shows no
reading, proceed as for DTCs 00283, 00285, 00287, 00290 "ABS Wheel Speed Sensor" DTC table page 01
-357
.
In order to check whether wheel speed sensors are properly allocated to each wheel, the vehicle must be raised. On
vehicles with manual transmission put the gear shift lever in neutral. On vehicles with automatic transmission move the
selector lever to position "N". Turn appropriate wheel by hand. Remaining drive wheels must be secured against turning.
When a vehicle is accelerated uniformly on a dry surface, the displayed value will increase continuously by whole
numbers; e.g. 6 km/h, 7 km/h, 8 km/h ... . The difference between displayed values 1-4 should not be more than 1 km/h
(error from out-of-round wheels). If the values jump, for instance from ...6km/h, 7 km/h, to 12 km/h...or if the difference
between the displayed values is greater than 1 km/h, then check the installation of the wheel speed sensors and rotors. Repair Manual, Brake System, Repair Group 45
