Vehicle diagnostics your shop can actually defend in a dispute
Record OBD-II fault codes, freeze-frame conditions, and repair verification as structured, auditable data — standalone, with no garage-management suite required.
The problem
Diagnostic scans get logged in a note box or a spreadsheet, so nobody can later prove which fault codes were present, what the freeze-frame conditions were, who cleared a code, or whether the repair was actually verified — until a warranty dispute or compliance check demands exactly that evidence.
The solution
Vehicle Diagnostics & Fault Codes gives every scan a structured record: stored and pending codes, freeze-frame data, photo evidence, a clearing audit trail, and a side-by-side verification scan — searchable, reportable, and ready to hand to a warranty provider.
Everything a compliance-grade diagnostic record needs
Every capability below is implemented in the module.
Structured scan records
Capture every OBD-II scan with stored and pending fault codes recorded as distinct, filterable data instead of free text, each scan auto-numbered (DIAG/YYYY/NNNNN) and tracked through a Draft to Confirmed to Done workflow.
Freeze-frame evidence
Preserve the exact operating conditions — RPM, coolant temperature, load, speed — present when each fault triggered, with photo and video attachments of the fault and dashboard conditions alongside the data.
Clearing audit trail
Every code that gets cleared is logged with who cleared it and when, turning the single biggest liability gap in warranty and roadworthiness disputes into a defensible, timestamped record.
Side-by-side verification
Run a post-repair verification scan and see resolved, still-present, and new codes compared directly against the original scan on one screen — proof the repair worked, not just a claim that it did.
Vehicle and customer history
Every vehicle and every customer carries a smart button straight to its diagnostic history, with odometer readings tracked alongside each scan so mileage and fault patterns stay connected.
Recurring-fault analysis
Group and filter diagnostic records by fault code, vehicle, system, or technician to see which codes keep recurring — turning isolated scans into an actionable maintenance signal.
Garage-maintained code library
Build and maintain your own fault code catalog — generic OBD-II plus manufacturer-specific codes — with system and severity classification, seeded with a starter OBD-II library out of the box.
Compliance-ready reporting
Generate a printable diagnostic certificate for a single scan or a multi-vehicle fault-code timeline report, ready to hand to a warranty provider, fleet owner, or regulator.
Standalone by design
Installs and runs on its own with no dependency on a garage-management, fleet, or accounting module — evaluate and adopt diagnostics without replatforming your existing repair workflow.
How it works
Scan the vehicle
Create a diagnostic scan against a vehicle, record stored and pending fault codes, freeze-frame conditions, and attach photos at the bay.
Confirm and clear
Move the scan to Confirmed, clear fault codes as repairs are made, and the system logs who cleared what and when.
Verify the repair
Run a post-repair verification scan and compare it against the original — resolved, still-present, and new codes shown side by side.
Report and close
Mark the scan Done, print a diagnostic certificate or timeline report, and review recurring-fault trends across the fleet.
Frequently asked
No sales fog. If your question isn't here, email us and we'll answer it the same way.
No. Vehicle Diagnostics & Fault Codes installs standalone on Base and Mail and runs on its own — it does not require any garage-management, fleet, or repair-order module to function.
