Volvo EVC

[1pfieffer1]

Hi, brand new to forum and at wits end trying to figure out electrical issue. We had a brownout condition at our marina and now our port engine has 15 trouble codes and won’t go into gear. 2008 Four Winns 358 w/trin Volvo Penta 5.7 GxiE engines and EVC C-3 with joystick. Port engine shows 15 trouble codes and a flashing orange warning light. Starboard engine shows 5 codes with no warning lights. MID 187, MID 200, MID 128 codes on port engine. If I take the starboard power train control unit and put it on port engine it will go into gear. Got new PCU for port engine from Volvo and was supposed to be flashed. Installed and no different than original. Swapped starboard PCU in again and it will go into heat fine. Finding it next to impossible to find anything on internet and local Volvo dealers only deal with smaller boats. Can anyone here here help?
