Diagnostics Process

Mr. Wilson’s ways re Diagnostics
Between remembering from the time, and years later looking back, the following is essentially what Mr. Wilson taught us in the late ’60 into the early ‘70s s in his Auto Shop classes at Burlington Central High School in Ontario.

I never realized how much I’d end up using his approach through the years, with work very much included in that statement.
(By “work”, I am referring to Machinery, Materials, Piping, Process and Controls issues I was involved with for periods of time throughout my working years.)
He was a top shelf diagnostician out of the auto mechanics trade, as well as being a very good wrench.
Plus, he was one of the best teachers I ever had, being one of my “Top 5” out of my K’ to Gr. 13 years.

Don’t be a “Parts Replacer”.
Be a Mechanic.

Always start with the basics, then go up the ladder of complexity from there.

1st: Assess the Problem.
2nd: Diagnose the Problem
3rd: Prescribe a solution to the Problem
Always in sequence and DON’T
• Bypass a step!
• Diagnose before Assessing!
• Prescribe before Diagnosing!

If it’s a new problem that arises immediately upon, or soon after, your work completion, no matter how unrelated it may appear to be on the surface, revisit that work as part of the Assessment.

When you do your work, imagine you’ll be the next guy working on vehicle and let that guide you re what to do, or not do.
(e.g. using anti-seize compound on exhaust bolting components, or replacing a barely useable brake system bleed screw)

Fix it right, fix it once.

Think, question, contemplate and never stop learning.

In hindsight, I saw how his approach was actually very universal in terms of a diagnostics process.
None of the concepts or principles were at all automotive specific.
It’s here for the intended benefit of all, while also being my perennial thank you to him.

B is often ignored.
C is often corrupted by not adhering to its proper sequence.
D is often ignored.
E, F & G were his approaches to Work
