The check of the usefulness of the functioning of measuring instruments of a combination of devices
Considered in the present manual of the car they are equipped of cushions of security (men). When there are executing any work near to sensors of punches, a column of direction or the panel desconectam men (to see cushions of Security - the general information). It does not carry out the control of the men's models through any type of the diagnostic equipment.
This proceeding only belongs to measuring of the instruments of the analogous type.
To measure instruments of consumption of fuel and temperature of the motor
They all leaned below of checks they are done in the included ignition (a key in the position of in).
If the arrow of the instrument of measuring constantly is in the null situation (a cold empty or driving tank), check a condition of a lock of security. If a lock of security as debit to be, to find the block of the corresponding sensor (to see the Head of the system of provision of Power and launch [sensor of consumption of fuel], or the Head of the system of Cooling and heating [sensor of temperature]). For a moment close the capture of sensor in the weight. There if will be a launch of arrow of instrument of measuring, substitute the sensor, otherwise through a land of point of passage of wire the sensor capture in the rear party of the instrument of measuring (in case of the necessity to see schemes of electric connections in the end of the present Chapter). Establishing the last capture of the firearm of the instrument of measuring if it moves in the very situation, the problem is composed in the bad functioning of a condition of an electrical system in the siege of a chain between the instrument of measuring and the sensor. If the arrow remains in the ancient (null) situation, check the second capture of the instrument of measuring in the presence of the tension in him. The absence of the tension they substitute the instrument of measuring.
