Too Low
4)
Repair Manual, Electrical Equipment, Repair Group 01
- Fill fuel tank and erase DTC memory
- Check DTC memory from instrument cluster.
4) The malfunction "Fuel Level too Low" will be stored if the fuel level in the tank is or was too low. The malfunction remains as
a static malfunction and will not be set a sporadic malfunction even if the customer fills the tank with fuel in the meantime.
Therefore it is possible to recognize malfunctions which have been stored due to lack of fuel e.g.: misfiring or malfunction
regarding oxygen sensor control.
