5 Forensic Case Studies —
Real Fraud, Real Data.
Each case below was detected using a single OBD scan. The vehicle data doesn't lie — these findings were invisible to a visual inspection.
LepreCon.AI — Car Intelligence
The claimant reported an accident at 137,869 km. The LepreCon OBD scan revealed a DAS (Driver Assistance System) fault already active — timestamped at 129,752 km, approximately 8,117 km before the reported incident.
| Fault Code | Status | ECU Mileage | System | Implication |
|---|---|---|---|---|
| U112300 | Active | 129,752 km | Front Sensors / DAS | Pre-existing — not from this accident |
LepreCon.AI — Car Intelligence
The vehicle's dashboard odometer showed 139,830 km. The EZS (Electronic Ignition Switch) module — which independently stores mileage — contained 259,072 km. The discrepancy points to deliberate rollback manipulation.
| Source | Recorded Mileage | Status |
|---|---|---|
| Dashboard odometer (displayed) | 139,830 km | Tampered |
| EZS module (internal ECU store) | 259,072 km | Authentic |
LepreCon.AI — Car Intelligence
The claimant submitted a warranty/insurance replacement claim for the high-voltage battery, citing range degradation. The OBD scan retrieved the battery management system's State of Health reading directly.
| Metric | Value | Threshold for replacement | Verdict |
|---|---|---|---|
| Battery SoH | 90.11% | Typically <70–75% | Within normal range |
| Mileage | 185,996 km | — | High use, expected wear |
LepreCon.AI — Car Intelligence
A replacement claim was submitted for the transmission after a reported accident. The LepreCon scan read the VIN stored inside the Transmission Control Module (TCM) — and it didn't match the vehicle.
| Module | Stored VIN | Matches vehicle? | Implication |
|---|---|---|---|
| Vehicle title / body | 1C4HJXDN1KWXXXXXX | — | Reference VIN |
| Transmission Control Module (TCM) | 1C4HJXFN4NWXXXXXX | NO | Different vehicle — undisclosed swap |
LepreCon.AI — Car Intelligence
The EDR (Event Data Recorder) captured vehicle behavior in the 5 seconds before impact. This data provides an objective, second-by-second reconstruction of driver behavior and vehicle state — independent of witness testimony.
| Phase | Time | Speed | Throttle | RPM | Steering | ABS | ESC |
|---|---|---|---|---|---|---|---|
| 1 — Full throttle | −5.0 to −3.5 s | 173–180 km/h | 100% | 5,376–5,504 | 176° | OFF | OFF |
| 2 — Brake attempt | −3.0 s | 171 km/h | 0% | ~5,450 | +48° | ON | ON |
| 3 — Loss of control | −2.5 to −2.0 s | 160–153 km/h | 0% | 5,500–5,130 | +34° to −56° | ON | ON |
| 4 — Pre-impact | −1.5 s | 141 km/h | 0% | ~4,700 | — | ON | ON |
| 5 — Impact | 0.0 s | 119 km/h | 0% | ~4,200 | ~141° | ON | intermittent |
