CSS Electronics - OBD2 DBC File - Decode Your Car Data

The OBD2 DBC file contains conversion rules for decoding raw OBD2 data to human-readable form (km/h, %, ...).

DBC is the standard CAN database format used in most CAN tools - incl. our CANedge software/APIs.

This OBD2 DBC contains ~150 of the standard Mode 01 PIDs - and you can easily extend it with e.g. propri

etary PIDs.

The database is 100% free and can be used natively with the CANedge series through the asammdf GUI/API.

OBD2 Data Logger - Easily Record Your Car Data

Do you want to record OBD2 data from your car?

This intro recaps the basics of OBD2 logging, the top 4 benefits and example use cases. You can also download sample OBD2 data from an Audi A4 (speed, RPM, ...).

Note: In contrast to most OBD2 dongles/scanners, the CANedge logs time series data to an SD card - which you can freely process via 100% free software/APIs. Learn below why the CANedge is ideal for OBD2 data logging at any scale. 

How does OBD2 data logging work?

Vehicle Data Car Record OBD2 OBD-II Logger Odometer Vehicle Distance

First, let us briefly recap the basics of OBD2: OBD2 offers a standardized set of parameters (OBD2 PIDs) that you can record - and easily decode - across most cars. 

To log OBD2 data involves 3 simple steps:

  1. Configure your OBD2 logger with a list of OBD2 PIDs
  2. Connect it in your car via an OBD2 adapter to start logging
  3. Extract the SD and decode the data via the free software/API

Top 4 benefits of OBD2 data logging

OBD2 logging lets you collect data from practically any car - below are the top benefits:

Driver/vehicle/part optimization

OBD2 data lets you e.g. monitor/optimize driving behavior and tune your car. OEMs can use the data to analyze the performance of new prototype parts in the field

Rare issue diagnostics

Rare issues in cars may occur briefly while driving, yet not during repairs. Logging the OBD2 data lets you analyze the period around an event to troubleshoot the problem

Car fleet management

OBD2 logging at fleet level enables e.g. driver behavior research, fuel cost reductions, reduced breakdowns, compliance, dispute handling and other valuable benefits

Data control & custom integration

With an OBD2 logger, you record the raw time series data, which can be extracted via SD or uploaded to your own server - for easy custom integration via open APIs
