I have a 2009 340 Monterey sport yacht with Volvo 5.7 gxi motors. I’m getting a caution check engine on my starboard engine, it comes on after about 10 minutes at running speed. All engine indications are normal and engine is running perfectly. When I switch on the oem mode I get the fault codes ( mid 120, Sid 90 , fmi 4 ) I cannot find these codes anywhere, in manuals, on line or from Volvo. Does anyone know where I can find the codes explanation or know what they mean? Thank you! Jerry
