•
done (after conventional bleeding) as otherwise damage to the booster pump can occur!

transmission/Tiptronic).
4. Carry out the following tests:
Check the system (brake lines and connections) for leaks.
Read out and erase the fault memory of the PSM control module with the Porsche System Tester 2
(PST 2). Additionally perform the static test in the PSM system.
Check electrical and hydraulic lines (brake lines) for incorrect assignment using the PST 2.
Then start the engine. The PSM−related lights in the instrument cluster must go out when the engine is
running.
Carry out a function check of the brakes. Then perform a short test drive and perform at least one ABS
control operation, taking the road conditions into consideration. Read out the PSM fault memory again.
There must not be any stored faults.
