Tool tutorialBeginnerEvidence-led
A short, question-driven list improves refresh rate and makes command-response relationships easier to see.
Why this matters
Tool value depends on the question it can answer safely, the vehicles and systems it truly supports, and the repeatability of the result.
Evidence to capture first
- Complaint and operating condition
- Command parameter
- Response parameter
- One corroborating value and system voltage
A disciplined path
- Save the full scan first
- Open the relevant module
- Select only the needed PIDs
- Set a repeatable trigger and export the recording
Decision point
Secure the tool and use a second person for any road data capture.
