A TEXA scan gives you the evidence: fault codes, live data and system status. What you test next decides whether the job gets fixed the first time or turns into parts swapping.

Diagnostic Coach is built around the FIXDIT process, a six-step method that starts with finding and inspecting evidence and then running a test plan where every test answers a specific question. Pair a capable scan tool with a repeatable process, and your techs spend less time guessing.

The six FIXDIT steps:

• F – Find Evidence: Gather everything: when it started, customer questions, history, conditions, codes from all modules, a full function test, a road test, a visual inspection and known bulletins.
• I – Inspect Evidence: Review it, decide what is relevant, how to replicate the fault and where to start.
• X – eXecute Diagnostic Plan: Plan what to test first, which tool to use, static or dynamic testing, what good and bad look like, and record the results.
• D – Determine the Cause: Find the root cause before fixing anything, using the 5 Whys.
• I – Implement Repair: Follow manufacturer procedures, special tools, calibrations and bulletins.
• T – Test: Retest under the same conditions, confirm the fix and consider the OBD drive cycle.

For fleets and mobile diesel techs, DPF, EGR and SCR faults are some of the most costly to get wrong. The Diesel Engine Systems course covers common rail injectors, fuel pressure, non-start faults, DPF regeneration, EGR operation, AdBlue dosing and SCR systems, with hands-on tests and case studies.

Recorded live sessions have also covered topics such as SCR and AdBlue faults, DPF and NOx sensor testing, and diesel injector testing.
