Read Measuring Value Block
(function 08)
The control module can transmit measured
values to the 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 from the
Bosch 5.0 series are contained in three display
groups, which can be accessed via their display
group numbers.
- Connect the VAG1551 Scan Tool (ST) and
select "Brake Electronics" via address word 03
page 01
-4 .
Notes:
When the printer is switched on, the contents of
the display will be printed out on the scan tool
log.
When reading the measuring value block, also
check wiring and connectors for loose
terminals.
- Check the control module version page 01
-52
and press the button.
