| 1. Disconnect a wire from the negative plug of the storage battery. |
| 2. Lift upwards a diagnostic socket from the gauge of a measuring instrument of the expense of air. |
| 3. Remove the case of the air filter. |
| 4. Disconnect a socket of the gauge of frequency of rotation of an entrance shaft / of a turbine wheel. |
|
5. Measure resistance between contacts 1 and 2 sockets. Resistance: 300~400 Ohm at 20 °C |
| 6. If resistance does not correspond to demanded values, replace the gauge. The inhaling moment: 8–11 Nm |
| 7. Establish the case of the air filter. |
| 8. Establish a diagnostic socket. |
| 9. Connect a wire to the negative plug of the storage battery. |
