When the ESX control throws a fault code mid-mat, this 203-page Bomag BW 170 AD, BW 174 AD, BW 174 AC Service Training PDF (OEM 008 098 20) is where diagnosis starts: the electric training section that decodes those faults fills more of the book than any other system. Six tandem roller variants are covered, including the AM Asphalt Manager versions, from the Cummins 4B3.3 diesel through travel, vibration and steering hydraulics. Circuit diagrams cover the sprinkler system, crabwalk steering and Asphalt Manager wiring, while separate hydraulic schematics map each variant's closed-loop travel circuit, and test point drawings show where to tap charge pressure. Set inlet valve clearance to 0.35 mm; know the F00 fuse runs 250A before you blame the harness. Guess wrong on an ESX fault and you pay for a pump you didn't need. Bookmarked and text-searchable, this PDF lets you confirm the code against the component listing before anything goes on order.
