The actual engine speed (MMI) is calculated by subtracting the dissipation torque from the engine torque.

Notes:

The vehicle must be raised until all wheels are
free to turn. Ask a colleague to help. The
colleague will have to check the wheels to
determine whether they turn freely.
You can stop the test sequence at any time by
pressing the -C- button.
To avoid overloading the components being
checked, they are actuated during the test
sequence for a period of 60 (or 90) seconds.
The actuator test will be terminated if the "
button" is not pressed within this period.

The ABS warning light and the red "brake
system malfunction" symbol blink during the
test.
Pressing the brake pedal repeatedly this
relieves the vacuum in the brake booster. For
this reason, the brake pedal must be pressed
harder in order to achieve the same braking
effect. Your work will be easier if you run the
engine briefly. This will build up vacuum in the
brake booster again.
