What are these markings ? (2017 ram)

Hey Karl Happy New Year. The example that I am using at 68-70 per hour is from an assembly plant perspective. If the defect is caught at the assembly plant audit per say an unlocked coil pack wire, then the assembly plant will hold their own audit to make sure that there are no more and that none will get shipped out to the dealerships. We only built 68-70 units per hour so that was all the engine line was required to check per hour, and yes the engine plant was required to send in a crew to inspect all the engines that were still in stock until that clean point was established.
