Hello,
ZOL! How are you? What about your English? Привет, вообщем, эта я так, к слову... :wink:
Попробуй сначала сделать так
What to do if your OBC displays only PPPP. If the OBC display suddenly starts to diplay only PPPP, you can reset it back to normal. Apparently this happens if there is an elctrical surge in the system (although it's never happened to me, despite many occasions of having to jump-start the car). First, press CODE, and then press the small recessed button on the lower right of the unit. After a second or two, the LED in the M MPH button will flash once, and the OBC is reset. All memory is wiped out, so you'll have to reset the date and time.

Сам не шарю, в инете есть инфа по этой трабле. Ищи по PPPP или AAAA - эта для америкосовских бэшек (патамушта в милях)
