ATS FORMULA: common fixes + simple tools + wiring diagrams

Please take note that despite all the modern expensive tools and repairs that are being marketed in 2014, TOP mechanics are still using these BASIC simple formula. See this picture below where an INTERMITTENT problem using a CHEAP pocket scanner and a wiring diagram is fixed (happened in November 2013).

ATS FORMULA

ATS WIRING FORMULA is tested in ACTUAL problems as shown here (that is me, Richard Trent in blue cover-all with safety "X' yellow marker on my back).

This was a 2007 GM Duramax diesel engine that the dealer have spent more than a week to fix a turbo line oil leak (not knowing it has an intermittent loss of power and stalling problem? Did they ask the driver/call owner what else is the problem besides the oil leak? When troubleshooting, always ask the vehicle history just like the doctor when the patient is SICK...)

*** Before the oil leak, the truck had INTERMITTENT stalling problem and I ordered a new wiring diagram software for our fleet which took almost a week to set up because it would not work on my MS Windows 8 laptop.

When the truck was picked up, it quit about a mile from the shop. Using a $45 OTC scanner, found it has no gas. A week later, it lost power and quit in the middle of the road 20 miles away from our shop.

Using the same pocket scanner, drove it back in limped mode (stuck at 30 km per hour or 2 hrs). Researched and printed the wiring diagrams (2 hrs because I have no idea what a heck is a GM Duramax diesel engine doing in GM BIG trucks!)...FOUND a bad wiring connector (15 minutes) at one sensor shown by the SAME cheap scanner! Of course we did not call the dealer because the shop owner had enough!
