7. WWH-OBD: The Next Evolution in Vehicle Diagnostics

WWH-OBD (World Wide Harmonized On-Board Diagnostics) represents an international standard for vehicle diagnostics, offering enhanced data types, detailed fault information, and improved diagnostic capabilities, as implemented by the United Nations.

• International Standard: WWH-OBD is an international standard used for vehicle diagnostics, implemented by the United Nations as part of the Global Technical Regulations (GTR) mandate.
• Vehicle Data Monitoring: It includes vehicle data monitoring such as emissions output and engine fault codes.
• Access to More Data Types: Currently, the OBDII PIDs used in Mode 1 are only one byte long, meaning that only up to 255 unique data types are available. WWH allows for more available data and provides the possibility of future expansion.
• More Detailed Fault Data: WWH expands the information contained in a fault. Unified Diagnostic Services (UDS) expands the 2-byte DTC into a 3-byte DTC, in which the third byte indicates the failure “mode.”

8. The Advantages of WWH-OBD: Enhanced Data and Fault Information

WWH-OBD offers several advantages over traditional OBD II systems, including access to more data types and more detailed fault information, empowering technicians with enhanced diagnostic capabilities.

• Access to More Data Types:
  • Currently, the OBDII PIDs used in Mode 1 are only one byte long, meaning that only up to 255 unique data types are available.
  • WWH allows for more available data and provides the possibility of future expansion.
• More Detailed Fault Data:
  • WWH expands the information contained in a fault.
  • Unified Diagnostic Services (UDS) expands the 2-byte DTC into a 3-byte DTC, in which the third byte indicates the failure “mode.”
• Consolidated Fault Codes:
  • With WWH, multiple fault codes are consolidated into one code with different failure modes indicated in the third byte of the DTC.
• Additional Fault Information:
  • WWH also gives more information on the fault such as severity/class and the status.
  • The severity indicates how soon you need to have the fault checked, while the class indicates which group the fault falls under according to GTR specifications.
  • The status of the fault indicates whether it is pending, confirmed or if the test for this fault has been completed in the current driving cycle.
• Improved Diagnostic Capabilities:
  • WWH-OBD expands on the current OBD II framework to give even more diagnostic information to the user.

9. Geotab’s Support for WWH-OBD: Enhancing Data Acquisition and Interpretation

• Limitations of OBD II: OBDII contains 10 standard modes to achieve the required diagnostic information for emission standards, but these modes have not been enough.
• Development of UDS Modes: Various UDS modes have been developed over the years since OBDII was implemented to enrich the available data.
• Proprietary PIDs: Each vehicle manufacturer uses their own proprietary PIDs (parameter IDs) and implements them via extra UDS modes.
• Access to Additional Information: Information that was not required via OBDII data (such as odometer and seatbelt use) was made available via UDS modes instead.
• Wider Range of Modes: UDS contains upwards of 20 additional modes to the current 10 standard modes available via OBDII, meaning that UDS has more information available.
• Incorporation of UDS Modes: WWH-OBD looks to incorporate the UDS modes with OBDII to enrich the data available for diagnostics, while continuing to keep a standardized process.
