Welcome back to another episode of Mastering Diagnostics with Motor Age Magazine’s Technical Editor, Brandon Steckler. He’s back with another golden nugget to help you along on your path to diagnostic efficiency.
In this episode, Brandon troubleshoots a transmission concern on his 2006 Chevrolet Silverado. The vehicle’s “tow/haul” mode will not function. Brandon takes the time to reference service repair information for a system wiring diagram to first gain an understanding of how the multiple components work together on a data bus to accomplish the goal of “tow/haul mode.”
He then uses the wiring diagram to identify the types of circuits he will be facing and where the components are located on the vehicle. Collectively, with this information in hand, Brandon sits comfortably at his kitchen table to come up with a diagnostic game plan before approaching the vehicle.
As always, Brandon strives to be as efficient as possible. With that, work as little as possible. More time is spent at the computer than is actually spent disassembling the vehicle. It’s this mindset that prevents time from being wasted during the diagnostic process.
Using his Fluke and a few pierce probes, Brandon quickly determines what is functional in the system. He then employs a bypass test to prove the system will function when the prescribed repair is completed. All of this is determined with very little disassembly and only a small amount of time invested.
Stick with Brandon on this episode of Mastering Diagnostics and learn how the bypass test will take your diagnostic efficiency to the next level!
