Volvo vnl def pump wiring rubbing, preventive maintenance save from derate

this is a short on the go video that i wanted to make for a long time, but didn't have a good example, if it was hard to hear i was trying to explain that wiring going from def pump to after-treatment module they rub against each other or on the bracket, it takes a little bit of time but closer to 400000 miles will come up with a def pump or acm codes, very common but not always or will just derate, what i have been doing is insulating the wiring in that area with some sort of rubber, hose or soft plastic, because once insulation is damaged, green corrosion starts to build up in the wiring, then hopefully you can see it to fix it. Before you securing the wiring back make sure to inspect the loom and wiring insulation if there is any wire you can see need it insulate it from weather
