Considered in the real Management of the car are equipped with safety cushions (SRS). At performance of any works near sensors of blows, a steering column or the dashboard disconnect SRS (see. Safety cushions - the general information). Do not make check of the SRS models by means of any type of the diagnostic equipment. |

This procedure belongs only to measuring instruments of analog type. |
Measuring instruments of fuel consumption and engine temperature
All listed below check are made at the included ignition (a key in the situation ON).
If the arrow of a measuring instrument constantly is in zero situation (an empty tank, or the cold engine), check a safety lock condition. If a safety lock as it should be, find the block of the corresponding sensor (see. Head of the Power supply system and release [fuel consumption sensor], or Head of System of cooling and heating [temperature sensor]). For an instant close the sensor socket on weight. If there will be a throw of an arrow of a measuring instrument, replace the sensor, otherwise by means of a wire crossing point earth the sensor plug on the back party of a measuring instrument (in case of need see schemes of electric connections at the end of the present Chapter). If when grounding the last plug of the shooter of a measuring instrument it will be displaced in the maximum situation, the problem consists in malfunction of a condition of electroconducting on a chain site between a measuring instrument and the sensor. If the arrow remains in former (zero) situation, check the second plug of a measuring instrument on tension existence on it. In the absence of tension replace a measuring instrument. |
