Renault 11 TXE on-board computer faults

[tanago]

Hi all,

The On-Board Computer on my Renault 11 TXE shows random static numbers. Currently it just shows "506" and doesnt change when I press any button! What can be wrong and can it be saved?

Thanks in advance!

Hi,

Is there any pictogram on your screen ? Such as Fuel tank, temperature unit, speed unit ?

Have you tried to disconnect the car battery (-) and put it back on again ?

You may find some directions here although it's in french, should you need any help please ask if you need translation :

Hi I managed to fix it, now it works but very limited

Outside temp - 50°
Fuel - 76L?? :zinzin:
Fuel consumption - missing

any ideas? :voyons:

I did some measurements with the multimeter and compared them to the ODB manual

Outside temp - 50°

showed about 150ohms which is outside the usual range so I ordered a new sensor

Fuel - 76L?? :zinzin:

the 1 & 4 connectors showed 241 ohms which is the max, maybe the fuel float is broken but connectors 1&3 that connect to the dashboard show the correct fuel level

anyone knows if the dashboard & odb have 2 different floats?

Fuel consumption - missing

the speedometer is disconnected from fuel flow meter, can that affect the fuel flow meter? or the fuel flow meter just faulty?
