I have had the PASM Failure message come on after I have been driving and the car is warmed up.
But when I turn the car off, the message usually disappears. However, the car has never hesitated to start.
Could this still be the weak battery issue?
Thanks everyone for the great feedback.

 

Are you running stock size and aspect ratio tires front & rear. Any chance that any of the tires are much more worn than the the others (i.e. fronts almost new and rears completely down to the bars, or just one tire that was replaced due to a puncture or failure)?

 

I think you are on to something, driving today in a heavy rain on very worn tires , all these lights came on. Parking brake , PASM, Auto start/stop, & Anti-Lock warning as i could feel car floating at around 63MPH

Did do a quick on & off with ignition once i got to where i was going, but still all waring lights came back on... i just suspect it over loaded all the sensors driving with bad tires.... i hope will go away with new tires and a battery reset.

< ok, after letting car sit, and wet roads went away.... so did all the nanny lights.... back to normal>

 

buming an old thread
PASM comes on occasionally./....drivin me nuts
driving it about 20km, and it PASM failure light comes on...then i shut off car, and restart car...its gone.
and driving it the next day...same thing...it comes on and then i restart the car no more mesages.
i test all the PASM functions...it all seems to work good...and when the light comes on, when i press the "suspension" button, nothing happens...normally it will say PASM sports, or PASM normal
this happens after i havent driven the car for few weeks...and its happening now every now and then.
any help would be great.;.
its a 997.1 GT3

 

Did you recently disconnect your battery and get this afterwards, sometimes it takes a few start stop cycles for the system to clear out. Or perhaps try disconnecting your battery and reconnect to see if it clears out after driving it again.

 

no, i didnt disconnect at all
all i did was plug in to the ctek for winter...and it was nice out so i took it out, and PASM on after around 10 mins of driving
