Diagnostic mode for Largus tidy
so here it is for: To enter the diagnostic mode, you need to insert the key into the ignition switch, press the pin on the instrument panel, and without releasing it, turn the key to the ignition position, while holding the pin for several seconds until the numbers appear on the screen, after which it need to let go. The existing mode has four windows with information that appear one after another when you briefly press the pin:
1. the first screen shows the firmware version of the on-board computer;
2. The second screen diagnoses the performance of all elements of the LCD display, turning them all on at the same time. In the event of a malfunction, one of the elements will not light up. I note that one of the elements on the left of the clock display is missing for all cars, because... for both types of time indications (12-hour and 24-hour) this element is not used;
3. The third screen shows the remaining fuel in the tank accurate to the nearest liter and provides more accurate information than the standard graphic bar. If there is an open circuit or short circuit fault, the display shows “- — -“. It is important to note that the fuel level sensor located in the gas tank does not reflect the amount of fuel filled above the 50 liter limit. Those. if you filled the gas tank with 51 or more liters, then the BC in diagnostic mode will still show only 50 liters;
5. The fifth screen informs about the presence or absence of malfunctions of the coolant level sensors, fuel level sensor and fuel consumption information system. If there are no existing or stored faults, the display shows “- — — — -“. – Stored and existing malfunctions of the coolant temperature sensor are displayed in the form “- — -TO” when the circuit is open, “- — -TC” when the circuit is short-circuited. Coolant temperature sensor malfunctions are not critical; You can ignore the “TO” fault if the engine is cold. – Stored and existing faults of the fuel level sensor are displayed in the form “-JO- -” when the circuit is open, “-JC- -” when there is a short circuit. – Stored and existing malfunctions of the fuel consumption information system are displayed as “D- — — -” in the absence of a fuel consumption signal. Malfunctions of the fuel consumption information system are only taken into account if the vehicle is equipped with an on-board computer. All “stored sensor faults” listed on the page are faults that were detected but no longer appear. If there are several stored or existing faults, they are shown on the same line.
To delete stored faults from the memory and exit the self-diagnosis mode, press and hold the pin pressed for several seconds;
refilling gasoline
Meanwhile, “drying out” is bad: you can find a lot of unpleasant adventures both for yourself and for the car. For example, burn out a fuel pump that will not have enough cooling. In addition, it will begin to pick up dirt that is in the tank of any car with high mileage. A lean mixture may damage the catalytic converter. When the engine is running at high speeds and the fuel mixture stops flowing into it (for example, in a long turn), this can lead to detonation and subsequent repairs. If it happens in a mountainous area, there is a risk of not being able to overcome the climb. And in general, any forced stop far from civilization is unsafe. In winter, you can simply freeze, afraid to leave the car. Do you think it's fiction? Alas, this happens. And not only in Siberia and the Far East, but even in central Russia. By the way, read in your spare time how to survive in this case.

How to drain gasoline from a Largus tank?
The second method will require access from below the car. Under the right rear wheel there is a fuel filter (not available on all trim levels). It is necessary to unscrew the fuel supply pipe, replacing the container first, and turn the ignition to position 2 so that the fuel pump turns on, which pumps gasoline out of the tank.
We take out the fuel pump.
The fuel pump on Largus is located under the rear seats.
In order for us to get to it, we recline (raise) the rear seats - “forward”. The hatch with the fuel pump is located under a black cover. To move the cover we need to unscrew the plastic fasteners and remove the top plastic casing.
We pull the floor covering a little to the side and the protective cover of the fuel pump is visible in front of us. We remove the protective cover and clean off all the dirt and dust near the plastic nut of the fuel pump. Now we can disconnect the supply fitting and unhook the connector.
To remove this connector, you need to have a small and thin screwdriver, otherwise you will not be able to bend it. Made a little awkwardly.
This will be the first and smallest difficulty we encountered.
