FAQ: Car Data Logger Software

What is the OBD2 protocol?

The OBD2 (On-Board Diagnostics II) protocol is a standardized system used in most cars and light trucks to provide access to vehicle data for diagnostics and monitoring. It specifies a range of standardized vehicle data that can be logged from your car.

What kind of data can I log with OBD2?

With OBD2, you can log a variety of parameters, including fuel system status, engine load, coolant temperature, fuel trim, fuel pressure, engine RPM, vehicle speed, intake air temperature, MAF air flow rate, throttle position, and more.

How do I decode raw OBD2 data?

To decode raw OBD2 data, you need a database of decoding rules and suitable OBD2 software. A 100% free OBD2 DBC file is available, containing the majority of the standardized Mode 01 OBD2 PID decoding rules. You can load your raw OBD2 data and the OBD2 DBC file in free software tools like asammdf or OBD2 dashboard integrations.

What is UDS?

The Unified Diagnostic Services (UDS) protocol is a communication protocol used within automotive ECU communication. It’s an off-board diagnostic protocol used when the vehicle is standing still, allowing for detailed diagnostics and data retrieval from specific ECUs.

How can I use the CANedge as an UDS data logger?

The CANedge can be configured to send UDS requests by sending a request frame and adding a flow control frame within X ms after the request. The resulting log files with UDS responses can be loaded in tools like CANalyzer or processed via the free Python CAN bus API.

Is my car compatible with OBD2 data logging?

Most cars and light trucks use the OBD2 standard. OBD2 has been mandatory in the USA since 1996 and in the EU since 2003. However, each vehicle model differs in terms of what OBD2 data parameters are supported. Check for metal pins in the CAN High (pin 6) and CAN Low (pin 14) pins of the OBD2 connector.

What are the different OBD2 signal protocols?

There are five OBD2 signal protocols in total: ISO 15765 (CAN), SAE J1850 (Ford Motor Company), SAE J1850 (General Motors), ISO 9141-2 (Chrysler and some EU/Asian vehicles), and ISO 14230 (KWP2000) (mainly used by EU manufacturers).

What’s the difference between OBD2 and J1939 data logging?

Generally, OBD2 data logging is used for cars and light trucks, while J1939 data logging is used for heavy-duty vehicles like trucks, tractors, and excavators. The J1939 protocol is a standardized protocol used in most heavy-duty vehicles today.

Can I stream OBD2 data in real-time?

Yes, the CLX000 series enables real-time streaming of raw CAN data and OBD2 data via USB. You can use our OBD2 streaming intro for more information.

Can I record GPS data with my OBD2 logger?

While some cars have built-in GPS, it’s rarely possible to extract the data via OBD2 or proprietary CAN data. For practical purposes, it’s recommended to use a CANedge including GNSS/IMU to record GNSS/IMU data timesynced with the CAN/OBD2 data.
