If you EVER found the need to investigate CAN-BUS HIGH SPEED Network with No Comms or No Start issues and would like to know…( Ignoring the Different GM Make-Model as being immaterial):

(1) How Does the CAN-BUS HIGH SPEED Network Function?
(2) What Diagnostic Tools Do I Need?

(a) High End Scan Tool (Snap-On Verus, “GYMKO” Tech 2, Autel MaxiDAS DS708, GM MDI, VXDIAG-NANO)

(b) An Inexpensive Oscilloscope with a Probes and Leads Kit (Hantek or PICO-Scope)

(c) A Lighted, $100.00 (16) Pin DLC “BOB” (Break Out Box)

(d) A Graphing Multi-Meter (Snap-On Vantage or Vantage Pro)


(3) What Diagnostic and Communication Issues are involved?
(4) What Diagnostic Tool Use Approach should I always take?

Then look no further than THIS Video in which “Crazy Ivan” (The Man From Phad) at Pine Hollow Auto Diagnostics… Teams up with Keith “Dino” De Fazio (The Man From New Level Auto) on Staten Island to Investigate & Explain HOW The CAN HIGH SPEED (GM-LAN) Data Bus Works and all that is entailed in TRACING AND FIXING A BROKEN CAN-BUS HIGH Network System, from Start to Finish.

THIS Video is THE Signature CAN-BUS HIGH SPEED Network System Training Session ALL Mechanics should want to Download, Save and Watch as often needed. :>)

THIS is a SUPERB Training Video to tag up with the Thread Topic because Eric "O" from South Main Auto up in Avoca, New York runs into some serious problems on a GMC Yukon Denali Truck .

It follows on that (as usual) he utilizes some EXCELLENT Diagnostic Tactics ...AND... Clever Tools with an approach that will help to "clear the scales from our eyes" in the Mechanical Biblical Sense and clarify SO Much about GM CAN Bus Network Communication Diagnostics:
