About Current, Stored and Registered Faults
Current Faults - These faults are detected while the car is running at idle or speed. They represent components
currently failing. These codes cannot be erased, and are only meaningful with the ignition on and the engine
running. Codes found in this system with the KOEO have no meaning. Components not present on the vehicle may
be flagged as failing by the cars internal diagnostics due to the generic nature of the cars software. This is
particularly true in C-Class (202) cars.
Stored or Permanent Faults - These faults are recorded in the permanent memory of the cars system controller
and are the main cause of MIL illumination. These codes can be erased.
Registered Faults - These faults are recorded in the temporary memory of the of the cars system controller. This
temporary memory records the number of times a component fails. When a certain number of failures has occurred
the fault is moved to permanent storage and the Check Engine Light (MIL) will be illuminated. On cars equipped
with Fault Registers the Check Engine Light may stay on after the Stored or Permanent Fault has been erased if
another occurrence of the fault has happened since the Permanent Fault was stored. To extinguish the light erase
the Stored and Registered faults. These codes can be erased.
