    Hello everyone hopefully I can find some answers here... New to the site...
    Truck
    2011 Mack Pinnacle CXU613 MP8
    My problem on my truck I have the lighting bolt ON
    Abs light ON
    ATC Light ON

    Codes
    136 Abs
    44 SID
    4 FMI
    Pressure Modulator Valve, Left
    This item has been replaced
    Codes are still present even after clearing with a computer.

    I have replaced item as stated above have checked 16 pin connector under fifth wheel cleaned and greased too

    Engine codes are still present... This all started several months ago when I had a front driver side steer abs sensor wire was cut so I replaced with new sensor then codes did quit showing for a week... After 1 week with new sensor the same exact codes came back....

    I'm thinking now I have a broke wire somewhere if anyone has any problems similar I would greatly appreciate any feedback/help!
