It s written "cut off power protection" , but in french , i send the picture, otherwise, when pcm is on, i have all the informations on the display of the instrument cluster,and the functions on the steering Wheel works fine with the pcm.

 

no idea except broken pcm3. not rare situation.

 

So, you think there s nothin to do with gateway...

 

to install new gateway is a good thing for diagnostic or coding, but this is not your case.
is pcm3 shows outside temperature, fuel cons. etc?

 

Yes, it shows all these informations.

 

Other question, when all is installed, what i have to code on the car? If it s possible to code something...

 

vlad, you seems to be russian, no? if yes then read here http://www.drive2.ru/l/6986951/

if all information is visible then it is broken pcm for sure.
coding enables navi, bluetooth, usb. for your 2004my it all can work without coding up to month, but it will gone.

 

Hi Serg,
I m back with my PCM3, it was a pcm unit defect.
I found an other unit but it was mounted in a cayenne S 957 without bose amplifier, is it possible to code it on a car with bose?
How to do it?
Thanks a lot for your anwer.
Best regards
Vladimir

 

sure, with PIWIS
