Test with Porsche System Tester 2
Note
• If work has been done on the hydraulic unit, the speed sensors and the cable harness or if the
hydraulic unit is replaced, a system check (functional check) must be performed with the Porsche
System Tester 2! This is the case, for example, after accident repairs! This prevents any confusion of
electrical or hydraulic lines and ensures faultless operation of the system!
• If certain brake lines are replaced, e.g. at the intermediate piece in the front−left wheel housing, a
system check or a swap test (swap test menu) must also be performed! Unintentional bending of the
brake lines could lead to incorrect hydraulic allocation, despite the different thread sizes used (M12 x
1 and M 10 x 1)!
• If there is a fault indication during operation (when no assembly work was carried out beforehand),
diagnosis and troubleshooting are also carried out with the Porsche System Tester 2! To do this, select
the PSM system and read out the fault memory there! The fault can then be localized using the
appropriate menus (Drive links/Actual values)!
• The Porsche System Tester 2 is connected to the diagnositic socket in the front left footwell in the
same way as for the 911 Carrera (996)! Entry takes place through the ABS system (automatic status
change after PSM)!
