What are EOBD codes?

EOBD, (European On-Board Diagnostic), is a system for warning the vehicle driver that there is a fault which may cause the emission levels to exceed those allowed by the European directive*. It also has the ability to store fault codes and ‘Freeze Frame’* Data, concerning an emission related incident.

What is an EOBD code reader?

EOBD systems monitor and store information from sensors throughout the car, e.g. air flow sensors and oxygen sensors. Sensor values outside an acceptable range, trigger a Diagnostic Trouble Code (DTC). New diagnostic tools can help you read and interpret these codes, and view the live sensor output.

What is the difference between Obdii and EOBD?

While OBD1 and OBD2 are different systems, OBD2 and EOBD are similar in virtually every aspect. The only difference is that EOBD is made for vehicles that are sold in Europe. On the other hand, OBD2 is designed for cars and light trucks that are targeted for the American market.

What an OBD2 stands for?

On-Board Diagnostic
OBD2, the abbreviation of On-Board Diagnostic, is the self-diagnostic system of all vehicles. All vehicles are equipped with a computer, Powertrain Control Module, which conducts regular self-check to make sure that the vehicle is in good condition.

What is a ECM code?

Definition. The PCM (powertrain control module, also known as ECM or engine control module in other vehicle makes) is referred as the ‘electrical brain’ of the vehicle. If the result of the self-check indicates a problem in the PCM, then it will store the Error Code P0606.
