Output Diagnosic Test Mode (DTM)

Note:

All functions which could previously be
performed with V.A.G 1551 can now also be
carried out with the tester VAS 5051.

The pump motor and the correct functioning of
the hydraulic circuits (allocation of brake lines to
wheel cylinders and function of valves) can be
checked via the output DTM for interchange or
leaks.

The vehicle must be raised until all wheels are
free to turn. (2nd mechanic required to rotate
wheels)

The -C- key can be used to exit the test
sequence at any time.

After depressing the brake pedal several times
the vacuum in the brake booster will be
exhausted. Therefore more pressure must be
applied to the brake pedal in order to attain the
same fluid pressure in brake system, as that
attained with vacuum.

When vacuum in brake booster is exhausted it
can happen that the wheels do not lock; start
engine and build-up vacuum in brake booster.
