Measured value block, reading

Note:
All functions that have been carried out so far
with V.A.G 1551 can now also be carried out with
the tester VAS 5051.
The control module can transfer a considerable
amount of test data. This test data delivers
information on the operational condition of the
system and/or sensors connected to it. In many
cases the transferred test data supports
troubleshooting and repair. The test data has
been summarized into single display groups
because all the information cannot be evaluated
at the same time. The information can be
selected via display group numbers.

Safety precautions

WARNING!

If the use of test and information devices
during a test drive is necessary, observe the
following:

You must always secure testing and
measuring equipment on the rear seat.

When vehicle is being driven, a second
technician must operate this equipment.
