C4s psm

Hey guys..new here...owner of a 2004 C4S cab, tip. Equipped with PSM. Previous owner replaced OE shocks. Question is..how do I know for sure if PSM is activated/working? I have not seen a PSM light up on instrument panel, not that Ive gotten in a situation where it would..but would like to ensure it is working. Thanks ahead of time

Shock change does not have any effect on PSM (Porsche Stability Management).
​ OTH 996s does not have PASM (Porsche Active Suspension Management) at all, it's offered to 997s and newer models.
PSM operation can be checked on slippery surface. Also inoperative/failed PSM will cause ABS disconnection and lots of red warnings on your dashboard.
