Understanding Porsche PASM Suspension or PDCC Chassis System Error Dashboard Warning Messages

If you see a PASM or PDCC failure message or warning light on your Porsche dashboard, it’s important to take the appropriate action. The message also can appear as chassis system failure or suspension fault. This section covers what to do when messages associated with PASM or PDCC appear on your Porsche dashboard. If you see a message for PSM then head over to our PSM page.

Why PASM  or PDCC Faults Need to Be Diagnosed Quickly

The PASM or PDCC system in your Porsche is an enhanced feature and critical safety system designed actively change the suspension characteristics for given different driving conditions.

Having a little fun and a sporty afternoon is better with firmer suspension and less body roll. On the other hand, a long road journey is always better with a soft and more compliant suspension. PASM and PDCC allows the driver and the car to control the way the suspension reacts to the driving conditions.

The PASM, PDCC, or Chassis warning messages are never very specific. Problems in the system vary dramatically from a simple ride height sensor, through a leaking strut, leaking hydraulic lines, to suspension pump problems or pressure sensors. Confusingly, the air based system will always attempt to level the car at least across one axle if possible. This often disguises the actual problem and sets multiple faults.

The PASM or PDCC system is connected to many of the vehicles operating systems including PSM. It is critical to performance driving safety and you should quickly have the fault investigated. Leaks in the system for example, cause the air or hydraulic pump to run excessively. Replacement of the PDCC pump is expensive.

Here’s What to do When You See PASM or PDCC Failure on Your Porsche Dashboard

Because the system is so much more than just ride height adjustment, we highly recommend you seek the professional guidance of a Porsche specialist to diagnose and make repairs to solve the PASM or PDCC failure message. The PDCC system requires specific PIWIS based bleeding procedures to correctly activate the system after repairs.
