2016 Mack Pinnacle check engine MP8.


Recommended Posts

Had the check engine light pop on this afternoon. Is there any easy way to see the actual code. I scrolled through the cluster menu to Diagnostic and the only two options that I had was for the Cluster diagnose and the Cluster part numbers as shown in the attachment below

You truck can be programmed by the dealership to allow you to view fault codes through the dash cluster. This feature was standard in the early years of the MP equipped trucks. Then drivers started clearing the codes before the trucks made it to the dealership for repairs , due to this the  feature was discontinued.  It can be turned on through software download from corporate.
