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

ENGINE 606.912 in MODEL 210.020 as of 1.6.96 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 with ignition "OFF" and after disconnecting the vehicle battery.

In the event of serious faults, the electronic power control (EPC) MIL (A1e43) 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:

• Crankshaft position sensor (L5/6)
• Fuel rack position sensor (Y23/1I1)
• IFI [ERE] accelerator pedal position sensor (R25/2)
• Fuel quantity actuator (IFI [ERE]) (Y23/1)
• EGR [ARF] 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 z. B.:

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