Being thorough pays off everytime!
When a vehicle arrives in your bay with a hesitation/"fish bite" misfire without any codes or any valuable data on your scan tool, where do you start your diagnostic approach?
Do you own an E-scope or are curious how the E-scope user interface is setup? In this Video, Brandon Steckler demonstrates key features of the ATS Escope in this Ignition Misfire Case study.
Proving circuit integrity is a key-point in this video. To always take that extra step in your diagnosis to be 100% sure that you know the vehicle will be fixed with your findings.
Great job Brandon and Trained by Techs! This is 2 birds with one stone for a lot of us who are interested in also seeing that Escope in action. Great video, keep it up.
What were the smooth running values on the scan tool?
very nice brandon thanks for sharing
Great job Brandon! Brian thanks for sharing.
Thanks Brian. I hope to see you again at the next training class/event. Are you by chance going to Super Saturday in PA oct 12th? All of us at TBT will be there. Some of us even hosting classes of our own.
I am planning on being there in October, maybe we will cross paths before then.
This vehicle is an 08 Volvo XC90 4.4L with misfires. Each COP has 4 wires, power, ground, trigger and a feedback wire. CH A is the COP 6 ground voltage drop at 3.4v. CH B is the COP 5 ground voltage drop at 0v CH C is the COP 6 power wire with no voltage drop at 14.4v CH D is the COP amps at the fuse. The normal COPs draw 10.6A and COP 6 draws only 4.2A because of the ground voltage
