Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1Original post

New to the site. Need some guidance. 2007 Cayman S (Canadian) replaced OEM audio for Kenwood Double DIN. No issues with install and audio quality is superb. Cadence amps and replaced all speakers except for factory Bose Sub on floor. Battery disconnected for 4 hours. Two failure warnings: PSM and ABS. Had Porsche tech reset through software hook up to OBDii port. Warnings still flashing. Car drives perfect but warnings not resetting. Any advice? Thank you so very much. Proud to be a new member of P9. Steve

POST 2Original post

I looked into doing that, but decided against it. Did not get the warm fuzzies in my tummy when I spoke to four different stereo shops. I don't have Bluetooth , but I feel that having the two year warranty on the system with my certification was worth keeping the old system . I'm sorry you are having problems with it. Did you do it yourself?

POST 3Original post

Thanks for the reply. The install was a professional job and highly recommended by other Porsche owners. I went to see their work in a similar car before taking the plunge. I have a feeling this is going to be a long road.

POST 4Original post

When I installed a Pioneer head unit in my '07 Cayman (Base), I also got a PSM failure message but it went away on its own after a few miles of driving as others said it would. I didn't get an ABS warning, though. I guess you had the Bose system in the car before...I know that it has some sort of crazy fiber optic loop that runs through the car and some other special wiring and communication requirements. I have Sound Package Plus so my life was a little simpler.

POST 5Original post

Since you state you had a " Porsche tech" clear the codes, I assume you took it to a real mechanic - or the Porsche dealer - not the stereo guys. Did this tech use PIWIS , Durametric, or just some generic scanner? A real Porsche tech has PIWIS and would of checked the code (to find the fault) if it didn't clear after a reset. Did you drive the car more than 100m. That usually clears codes associated with having the battery disconnected.

POST 6Original post

Whenever you disconnect the battery the PSM warning will come on, after driving a bit it will turn off. I have never gotten the abs warning though so cant say what is going on with that.
