987.2 - blank PCM screen and other strange behaviour

[finestjammy]

Hi All

I started the car up yesterday and the radio came on (as it always does annoyingly) but the screen remained blank. I was leaving for a hospital appointment so didn't have chance to investigate. When I got home I checked the fuses but all were fine. I switched the ignition on and it sprang back to life. One thing I have now noticed is that when starting the engine the PCM 'reboots' and the Porsche logo startup sequence commences. Thing is I can't remember if it's always done this.

Would a low battery cause this? It's almost like the battery power is being reserved/diverted to the starter and there's no enough left to keep the PCM powered. I'll check the voltage at the terminals when I get chance.

Any help appreciated.

James.

Switch the source to aux and it'll be silent when you get in.

The Porsche logo comes up from time to time on my 997.2 PCM.

Thanks for the tip, that will save my sanity a little

I'll keep an eye on the Porsche logo situation.
