They will have grave consequences for the earth’s biosphere unless we dramatically reduce and control the pollutant emissions of motor vehicles, among other things.

The On-Board Diagnosis System (or OBD) was introduced for this purpose. OBD is a diagnosis system integrated in the vehicle’s engine management system which continuously monitors the components affecting exhaust emissions. If a fault occurs, OBD recognizes it, stores it and indicates it via the self-diagnosis fault warning lamp (MIL).

OBD II is the second generation of engine management systems with diagnosis capability. OBD II offers the following advantages over periodic vehicle checks:

  • It checks pollutant emissions continuously,
  • indicates malfunctions early, and
  • provides full-fledged diagnosis functions which simplify troubleshooting and fault correction for workshop personnel.

In the long term, we will expand the capabilities of the diagnosis system to make it possible to detect faults in the exhaust system that are detrimental to emission behavior by means of a simple OBD reader, even during spot checks.
