What is Porsche PASM sports suspension?
Porsche’s Active Suspension Management system (PASM) is an electronic active damping system which is available as an optional extra on all of the German manufacturer’s current, lesser-powered Boxster, Cayman, Macan and Cayenne models – but is standard on the more powerful versions.
Why is my PSM not working on my Porsche?
Brake light switch causes intermittent PSM failure. It may need adjustment or replacement even if the brake lights work. To find out why your Porsche system has failed, start by reading the ABS / PSM module’s trouble codes. Porsche PSM failures can be diagnosed with a diagnostic scanner.
When do you get the warning PSM failure message?
Message is ‘Warning PSM Failure’ followed by ‘Warning Auto Start Stop Failure’. Then, maybe the brakes stay slightly applied, or not depending on how it feels. Twice in six months and always on cold days. I know it needs OPC love and care but I can’t get it to then for about three weeks.
What to do when ABS and PSM fail?
Once you return the SAS, you need to carry out steering angle sensor calibration. If you are getting ABS failure and PSM failure, drive to the workshop message on the dashboard; when you press the brake pedal or start to drive, the problem may be the brake light switch.
Why is my PSM not working on my 981?
Intermittent PSM failure comes up on multi screen on 981. Seems to be linked to a hot footwell on cold days. Blast cooler air at it and stop, switch off completely – key out – restart and it has cleared and will not do it again for days, or an hour later with the heater set to ‘feet’ and toasty.
