OBD Log Upload

Standard OBD-II scanners often stop at triggered trouble codes, but modern vehicles emit hundreds of parameters per second over CAN bus. Uploading raw logs—captured using professional diagnostic tools—enables deeper analysis of live trends, such as fuel trim oscillations, torque converter lockup timing, or throttle response latency. This granular data reveals intermittent issues that fail to set codes but impact driveability or efficiency.

The system correlates timestamps, bus traffic, and ECU addresses against known fault signatures. For example, a delay in hybrid inverter coolant flow after hard acceleration might not trigger a code but could indicate early pump degradation. Logs captured during a cold start cycle help identify sensor drift, while highway cruise data reveals transmission shift point inconsistencies. We support industry-standard formats like .blf, .asc, and .csv with timestamped frames.

Fleet operators benefit from batch upload—drag-and-drop multiple logs to spot recurring patterns across vehicles. A sudden cluster of catalytic converter-related diagnostic trouble codes across a fleet could point to a specific exhaust composition issue from a fuel batch rather than component failure. Logs can be anonymized and stripped of VIN before upload if preferred, and all transmissions are encrypted in transit and at rest.
