Recording, Playback and Reports

How do I record live data to catch an intermittent problem?

Select only the PIDs related to the symptom, start a recording or use a trigger, drive until the problem happens, then save the file and review it frame by frame on the scan tool or a computer.

What should a scan report include for a customer?

Short answer: A useful scan report shows the vehicle details, date, all modules scanned, codes found with descriptions, and, after repairs, a post-repair scan showing the codes cleared and systems verified.

Scan reports document the condition of the vehicle before and after work. They help customers understand what was found and support insurance and warranty conversations.

Most professional tools generate a report with the VIN, mileage, a list of modules and their status, and code details. Add notes explaining which codes relate to the customer's concern and which are historical or unrelated.

Keep the pre-scan and post-scan reports with the repair order. Many tools email or print reports directly or save them as PDF files. Make sure the report includes the date and time so it is clear when each scan was taken. Avoid sharing reports that contain other customers' information.

Can I review recorded scan tool data on a computer?

Short answer: Many professional scan tools let you export recordings or reports to a computer through cloud accounts, USB or email, which makes it easier to zoom in on graphs and share data.

Reviewing a recording on a large screen helps when comparing many signals at once. Depending on the tool, recordings may be exported as data files, spreadsheets or images, or viewed through the maker's online portal.

Check the tool's documentation for export options and file formats. Some formats only open in the maker's viewer software. Organize files with the VIN, date and complaint in the file name so they can be found later.

Sharing recordings with a remote expert or another technician can speed up diagnosis. Remove personal customer information before sharing outside the shop. Keep a library of known-good recordings for common vehicles to compare against.

Why is my recorded data missing the moment the problem occurred?

Short answer: The recording may have stopped due to buffer limits, the trigger may not have caught the event, the PID refresh rate may be too slow, or the tool may have lost connection during the drive.

Scan tool recordings have limits. Some tools record a fixed number of frames or a limited time window, and older data gets overwritten. If you selected many PIDs, each one updates more slowly, and a brief dropout can fall between samples.

Reduce the PID list to the essentials to speed up the refresh rate. Use a trigger or marker that saves data before and after the event. Check that the tool's storage has room and that its battery is charged.

For very fast events, such as a sensor that drops out for milliseconds, a scope is better than scan data. Connect the scope to the suspect circuit and use a long time base or trigger to catch the glitch.

What is a digital vehicle inspection on a scan tool?

Short answer: A digital vehicle inspection uses photos, notes and checklists, sometimes with scan results, to document a vehicle's condition and share findings with the customer electronically.

Many shops use digital inspections to show customers what technicians find. Photos of worn brakes, leaking components and tire tread depth make recommendations easier to understand.

Some scan tool platforms include inspection checklists, photo capture and report generation, and a few integrate tire tread and brake wear data from compatible tools. Others connect with shop management software.

Whichever system you use, keep inspections consistent and honest. Photograph the problem clearly and note measurements. Send the report promptly so the customer can make decisions while the vehicle is still on the lift. Keep inspection records with the repair order, and never take photos under a raised vehicle unless it is safely supported on the lift arms or stands.
