    2011 Volvo L90f " i-ecu reduced communication"

    Well....problem solved. For whatever reason this machine had two aux light harnesses run from the fuse panel area up the right rear cab corner and up above the headliner. It had two plugs labeled "ca" right near the socket bank. The opposite end of the ca plug which was plugged in, had no...

    This is the plug i found disconnected. It is the center plug of a 3 plug bank directly behind the right console, mounted on the rear firewall of the cab. I found the strobe power and ground wires in that plug, powered them up and the beacon works as it should. I had no power or ground at the...

    2011 Volvo L90f " i-ecu reduced communication"

    Hopefully the local volvo experts can chime in on this one..... i have been successfully working through the random issues and oversights that were plaguing this machine. Today i came across a head scratcher. I was diagnosing the rotating beacon light as it was not working. I powered up the...

    L90F volvo error messages

    I can always count on you for the straight scoop! Is there any parameter i can watch on the screen while operating to see if it is in fact the injectors returning too much fuel?
