Lighting of engine diagnosis (EOBD) warning lamp
The engine diagnosis warning lamp indicates a failure of a component or of a system relating to emissions if it is causing an increase in emissions,
to exceed the legal limits.
Ignition misfirings, which carry the risk of destroying the catalytic converter, cause the engine diagnosis warning lamp to flash.
The engine diagnosis warning lamp is not used for any other purpose, except if there a risk of destruction of the engine or a risk for the safety of the
vehicle occupants.
Access to the EOBD fault codes
Access to the memorised fault codes is open to any trained person equipped with a normalised diagnostic tool known as SCANTOOL with which the ECU
permits dialogue.
Access to the diagnostic codes is as follows :
Mode 1 : reading of the number of fault codes and of the engine speed (dynamic)
Mode 2 : reading of the fixed datastream (associated variables)
Mode 3 : reading of the fault codes
Mode 4 : deletion of fault codes
