Motor Age Technical Editor Brandon Steckler is back with Wrench Tales #16 and his very good friend from Jacksonville, FL, Tony Mossuto. Tony runs a very successfully shop in the Jacksonville area called Everything Automotive and he was faced with what appears to be a very challenging subject vehicle.
Tony encountered a 2015 Jeep Grand Cherokee suffering from multiple symptoms including “No-crank conditions,” “Runs, but won’t come out of 'park',” accompanied by nearly 60 DTCs spread across 14 different control units and on two different bus networks.
Synonymously throughout the automotive community most techs will concur that intermittent network faults tend to be some of the most challenging faults to encounter. However, the biggest part of that challenge is typically a lack of efficient diagnostic approach.
Listen carefully to Tony and Brandon as this story of diagnostic success is shared, amazingly with virtually no disassembly whatsoever. Tony fixed this network fault issue with logic, patience and the implementation of a solid game plan.
This is among the great diagnostic techniques that simply can’t be learned from reading flowcharts and factory service information. Want to know more? Be sure to tune into this episode of Wrench Tales!
