The anticreeping code of radio is thus erased.

3. Raise the car.
4. Reduce pressure паров fuels. For this purpose quickly open a cover of a bulk mouth of a fuel tank.
5. Remove a protective casing from the fuel level sensor. Pay attention to that electric wires or a hose for fuel plum were not clamped.
6. Remove the tip from the fuel level sensor.
7. Unscrew a carving stopper of the drain valve.
8. Twist a drain hose together with the locking valve in the drain gate.
9. Open a cover of a bulk mouth of a fuel tank, open the locking valve and merge fuel in suitable capacity.
10. Take a drain hose and screw up a carving stopper with the moment of 15 N of m. Previously check on damages a sealing ring of round section, if necessary, replace it.
11. Get the tip on the fuel level sensor, mount a protective casing.
