1. Understanding OBD2 Data Logging

OBD2 data logging involves capturing information from your car’s On-Board Diagnostics system. According to the SAE J1979 standard, OBD2 provides a standardized set of parameters across most vehicles, enabling you to monitor various aspects of your car’s performance. This process typically involves three key steps:

1. Configuring your OBD2 logger with specific OBD2 PIDs (Parameter IDs).
2. Connecting the logger to your car via an OBD2 adapter.
3. Extracting the data and decoding it using specialized software or APIs.

MERCEDES-DIAGNOSTIC-TOOL.EDU.VN can provide detailed guidance on selecting and configuring the right OBD2 logger for your Mercedes, ensuring you capture the most relevant data for your needs.

9. Frequently Asked Questions About OBD2 Data Logging

9.1. What OBD2 parameters can I log from my car?

The OBD2 protocol (SAE J1979) specifies a range of standardized vehicle data that can be logged. Available parameters include:

• Fuel system status
• Engine load
• Coolant temperature
• Fuel trim
• Fuel pressure
• Intake manifold pressure
• Engine RPM
• Vehicle speed
• Intake air temperature
• MAF air flow rate
• Throttle position
• Air status
• Oxygen sensor status
• Runtime since engine start
• Distance with MIL on
• Fuel tank level input
• System vapor pressure
• Absolute load value
• Hybrid battery pack life
• Engine oil temperature
• Engine fuel rate
• Torque
• VIN
• Various DTCs

Consult the OBD2 PID Wiki page or the SAE J1979 standard for further details.

9.2. How do I decode raw OBD2 data into physical values?

To decode raw OBD2 data, you need a database of decoding rules and suitable OBD2 software. We offer a free OBD2 DBC file containing the majority of standardized Mode 01 OBD2 PID decoding rules.

9.3. What is UDS?

The Unified Diagnostic Services protocol (UDS, ISO 14229-1) is a communication protocol used within automotive ECU communication. An UDS diagnostic tool can be used to send requests messages into the CAN bus, with the purpose of e.g. retrieving information from specific ECUs. While OBD2 is intended as an on-board diagnostics protocol (for while the vehicle is moving), UDS is intended as an off-board diagnostic protocol (for when the vehicle is standing still).

9.4. How to make UDS requests over ISO-TP (ISO 15765-2)?

Requesting OBD2 PIDs is relatively simple: An OBD2 scan tool or OBD2 data logger sends a specific CAN frame (the OBD2 request) and if the car supports the OBD2 PID, it responds with a single CAN frame. In contrast, UDS requests may require performing transport protocol requests. The communication flow may be as follows:

• An ‘UDS data logger’ sends a request frame specifying the service ID (SID) and data identifier (DID) of interest
• The car responds with a first frame, which contains the SID, DID, total message length and initial payload bytes
• Shortly after the first frame, the UDS logger acknowledges the first frame by sending a flow control frame
• After this, the ECU sends consequtive frames with the remaining payload of the message

9.5. UDS and OBD2 extended PIDs for car data logging?

The UDS service ID (SID) and the data identifiers (DID) are sometimes combined into one ID and referred to as an ‘extended OBD2 PID’ – for example 0x220101. Recording UDS data via service 0x22 requests is sometimes used to extract car data beyond what is available through service 01 OBD2 PID requests. For example, some electric cars provide access to State of Charge (SoC%) via UDS requests under service 0x22.

9.6. Using the CANedge as an UDS data logger?

The CANedge can be configured to send UDS requests. This is done by sending a request frame and adding a flow control frame within X ms after the request. When done right, this triggers the full sequence of UDS responses. The resulting log files with UDS responses can e.g. be loaded in tools like CANalyzer (by converting the MF4 data to Vector ASC) for decoding. Alternatively, the multi-frame UDS response data can be processed via our free Python CAN bus API e.g. to push parameters to a Grafana UDS dashboard.

9.7. Will OBD2 data logging work with my car?

Most likely, yes. 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, and some manufacturers have begun restricting access to OBD2 data.

9.8. What if my car uses a different OBD2 signal protocol?

There are 5 OBD2 signal protocols in total:

• ISO 15765 (CAN): Dominant, required in all vehicles sold in the USA since 2008
• SAE J1850: Standard of the Ford Motor Company
• SAE J1850: Standard of General Motors
• ISO 9141-2: Used by Chrysler and some EU/Asian vehicles
• ISO 14230 (KWP2000): Mainly used by EU manufacturers

The CANedge/CLX000 supports CAN-based OBD2. Contact us if you’re unsure whether your car is supported.

9.9. What is the difference between OBD2 data logging and J1939 data logging?

OBD2 is typically used for cars and light trucks, while J1939 is used for heavy-duty vehicles like trucks, tractors, and excavators. J1939 requires a J1939 DBC file for decoding.

9.10. Which data logger should I choose: CANedge or CLX000?

If your primary goal is to log data to an SD card, the CANedge series is recommended. If you need to stream OBD2 data in real-time via USB to your PC, the CLX000 series is a better choice.

9.11. Can I stream OBD2 data in real-time via USB?

Yes, the CLX000 series enables real-time streaming of raw CAN data and OBD2 data via USB.

9.12. What is the difference between raw CAN data and OBD2 data?

Raw CAN data is broadcasted by the car sensors and used by the car itself to communicate. OBD2 data is available only “on-request.”

9.13. What are the different types of OBD2 devices?

• OBD2 Scanners: Used for diagnostic purposes.
• OBD2 Dongles: Small, low-cost Bluetooth OBD2 readers.
• OBD2 Data Loggers: Record OBD2 timeseries data to an SD card.
• OBD2 WiFi/LTE Loggers: Support WiFi or 3G/4G data transfer.
• OBD2 Interfaces: Allow for real-time streaming of OBD2 data to a PC via USB.

9.14. Will the OBD2 data logger drain my car battery?

In most cases, the logger will turn on/off with the ignition. However, in some vehicles, the OBD2 connector power supply is directly wired to the battery. Verify whether your logger turns on/off with your vehicle by evaluating the LEDs after the car has been turned off for 15-20 minutes.

9.15. Can I get GPS data with my OBD2 data logger?

While your car may have a built-in GPS, it’s rarely possible to extract the data via OBD2 or the proprietary CAN data. Using a CANedge with GNSS/IMU is recommended for recording GPS data.
