1) Put the key in the ignition, but keep the key without contact (Completely closed). The LCD panel turns off.
2) Press the odometer button on the board.
3) Keep the button pressed, turn the ignition key (Without activating the engine). Press and hold the button.
4) After three seconds, the screen shows the number 011301. Then you just have to change the functions of the computer until you see the liters in the gas tank
In the test mode you can know how many liters the tank has. It is good for those who do not have a computer on board and wants to know what the average consumption is.
PS: Apologies for the poor quality, it was recorded with a cell phone and at night! XD
Edit 1: Summary of the screens / indications:
1 Number of the switchboard software.
Â 2 Test (on) all the indicators
3 Liters of reserve. If there was an error, indicate "—"
4 "0.0 consumption". Fuel flow liters / hour. If there was an error, indicate "-"
5 "— | -o." It shows information of the defective sensors, by means of different codes.
6 "- – -TO" water temperature
7 "- – -TC" short? water temperature
8 "-JO- -" fuel level sensor
9 "-JC- -" short circuit? of the fuel level sensor
10 "D- – – -" the fuel flow sensor does not signal
I leave a link to the workshop manual of the Renault-Dacia Logan, which in many respects is equal to the Sandero and something to the Duster ..:
The following link is only for the Fault codes that appear on the screen:
