Checking ABS and PSM

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2004 Porsche Boxster, 2003 Porsche Boxster, 2002 Porsche Boxster, 2001 Porsche Boxster, and 2000 Porsche Boxster. However, it is still accessible from the selected car via links, so may be relevant.

If work has been done on the hydraulic unit -D-, the speed sensors and the cable harness or if the hydraulic unit -D- 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 - for example, at the intermediate piece in the front-left wheel housing -E- - a system check or a swap test (swap test menu for vehicles with PSM) 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 ABS or PSM system and read out the fault memory there! The fault can then be localized using the appropriate menus (Drive links/Actual values)!
