IFI fault storage function - GF07.12-P-3101HC

ENGINE 606.912 in MODEL 210.020 except CODE (491) U.S. version

ENGINE 606.912 in MODEL 210.020 to 31.5.96 with CODE (491) U.S. version

Notes on DTC memory

DTC memory: fault display
current faults : are displayed against a gray field

stored faults : are shown against a light background

All inputs and outputs are checked for plausibility during operation.

All faults that occur are stored in the DTC memory of the IFI [ERE] control module (N3/7).

The faults remain stored when the ignition is "OFF" and after disconnecting the vehicle battery.

In the event of serious faults, the electronic diesel control (EDC) MIL (A1e34) will light.

Version

Emissions-related faults trigger the CHECK ENGINE malfunction indicator lamp (A1e26) and the

CHECK ENGINE

ENGINE ELECTRONICS

indicator in the multifunction display.

The faults are marked by an OBD fault code.

Such faults include:

Lifting sender B28/3
EGR [ARF] vacuum transducer Y31/1
Pressure control flap vacuum transducer Y31/2

Fault ambient data

The fault ambient data at the time the fault was stored can also be displayed with the HHT. Only the ambient data which existed when the fault occurred for the first time is stored. The ambient data is spread over several display screens (up to 8 display screens), The last two display screens are reserved exclusively for development.

Display screens showing the result √/F point to the fault causes such as:

Voltage too high
Voltage too low
Signal too strong
Signal too weak
Value implausible
