Enhanced OBD Databases

Since OBD-II is emission oriented, there are many desired parameters that are not available from OBD-II. These include:

  • Torque
  • Hybrid operating parameters (SOC, motor/generator speed & torque)
  • Fuel Consumption from injectors
  • Odometer
  • ABS & Stability parameters
  • Air Conditioner status
  • Ride and Handling parameters ( brake and steering)

One potential way to gain access to this information is the Enhanced OBD (EOBD) database used by the service scan tool. Each OEM has its own database relating the network messages to engineering values, and each database has its own additional charge associated with it. Contact us for details.

HEM Data has EOBD databases relating parameters to CAN messages for a variety of vehicle manufacturers including:

  • Chrysler
  • Ford
  • GM
  • Honda
  • Hyundai
  • Kia
  • Mazda
  • Mercedes
  • Nissan
  • Toyota

Check with HEM Data if the OEM of interest is not listed.
