Porsche system guide
Porsche PASM Explained
Porsche Active Suspension Management electronically adjusts damper behaviour. PASM does not automatically mean air suspension: many PASM vehicles use steel springs with electronically controlled dampers.
What the system does
- Varies damping to balance body control and ride comfort.
- Responds to drive mode and vehicle sensor inputs.
- May work alongside air suspension, PDCC or other chassis systems.
Models and applications
- Available or standard on selected 911 and 718 variants.
- Used with selected Cayenne, Macan and Panamera suspension configurations.
- Integrated into Taycan chassis configurations where fitted.
Normal characteristics
- Ride firmness changes with mode and road input.
- A firmer response in a sport mode is expected.
- Fitment and ride height vary by model and option.
Warning signs
- A PASM or chassis-system message.
- Persistent harshness, poor control or a damper leak.
- Uneven tyre wear, knocking or steering instability.
Diagnostic considerations
- Confirm PASM equipment from vehicle data.
- Combine module data with damper, bush, joint, tyre and alignment checks.
- Verify calibration requirements after replacement.
When inspection is needed
A warning or symptom does not identify the failed part. DIGI-TEC confirms compatible access and the appropriate initial test for the exact vehicle.
