Devices combination
Removal and installation
Desconecte a wire of the negative capture ("-") of the battery recarregável.
Withdraw a frame of a combination of devices, having unscrewed the screw of fixation.
The installation is executed as it must be, the return to the removal.
Check of technical condition
Speedometer
An inspection of the fairness of indications of a speedometer has to be executed in the special bookcase in the conditions of the station of service of the cars of Hyundai.
In the tires use or a detour of the pressure of the standard the mistake of a speedometer increases in them (it labels. 7.6).

Tacômetro
Establish and join a tacômetro of control according to the maintenance education.
|
PREVENTION
The modification of the polarity in the connection of a tacômetro can lead to the damage of his transistor and diodes.
In the moment of removal and installation of a tacômetro they try not to leave it and it preserves against strong punches.
|
In the work motor they compare indications of a tacômetro of control to indications of a regular tacômetro. In the excess of limits of the admission of measurements they substitute a tacômetro (it labels. 7.7).

Rate of level of fuel
Since the check of the capacity of work separates the capture of contact of the sensor of level of fuel.
Annex to 3,4 lamp of control of W and with a voltage of work of 12 V to contacts "2" and "3" parts of end of the capture of the sensor of level of fuel.
Include the ignition and it is convinced what the control lamp illuminates, and the arrow of the rate of the level of the fuel moves for the situation "F" (a full tank).
Sensor of level of fuel
Check a resistance ohmmeter between contacts "2" and "3" sensors in the moment of each provision of a buoy ("Е" – an empty tank; "1/2" – way of a tank; "F" – a full tank) (it labels. 7.8).
Check the smoothness of the modification of the resistance moving a buoy of the situation "E" to the situation "F".

Sensor of reserve of fuel
Annex a lamp of control (with a voltage of work of 12 V and 3,4 W) and the battery recarregável constantly to sensor conclusions. Board the sensor in the water.
In the thermistor boarded in the water the lamp of control of the rate must not be burned, in the tuck out of the water — it has to be burned.
|
TO OBSERVE
In the bad functioning they substitute the sensor of level of joined fuel.
|
|
PREVENTION
In the ending of this check they rub the sensor dry and install it in the fuel tank.

The rate of the temperature of cooling the liquid
In a driving compartment desconectam the capture of contact of the sensor of the temperature of cooling the liquid.
Include the ignition and be convinced that the arrow of the rate of the temperature of cooling the liquid is in the situation "coldly".
Put the ignition out.
Annex a lamp of control (with a voltage of work of 12 V and 3,4 W) to the contact of a part of end of the capture of the sensor and to "meditate".
Include the ignition. The control lamp has to be burned, and the arrow of the rate to be in the "hot" situation.
If the result of the check does not correspond affirmed in top, substitute the rate of the temperature, then again control system.
The sensor of the temperature of cooling the liquid
Check a resistance ohmmeter between contact "2" sensors and "weight".
If the resistance does not correspond specified in the etiquette. 7.9, substitutes the sensor.

Sensor of pressure of oil
In the idle motor available chains are convinced between contact of the sensor of the pressure of oil and "weight".
In the work motor to be convinced of the lack of a chain between contact of the sensor and "weight".
If the result of the check does not correspond affirmed in top, substitute the sensor.
Lamp of control of pressure of oil
Desconecte the capture of contact of the sensor of the pressure of oil and sole the contact of a wire of the sensor with "the weight".
Include the ignition and it is convinced what the control lamp illuminates. If the lamp is not burned, check a lamp and wires.
Sensor of level of fluid of brake
Separate the capture of sensor located in a tank of fluid of brake.
Any nucleus to press the sensor (buoy), available chains are convinced between contacts "1" and "2" sensors.
Lamp of control of level of fluid of brake
Launch the motor. Put the brake of parking out.
Separate the capture of the sensor of the level of fluid of brake.
Join contacts of a part do away with the capture of the sensor with "the weight".
One convinces of the fire of a lamp of control.
Switch of a lamp of control of the system of brakes of parking
The switch of a lamp of control of the brake of parking of the type of press (the switch of trailer) is located below the lever of the brake of parking. For the agreement of the position of the switch it is necessary to move an arm of switch above or down for the lever of the walk of the system of brakes of parking installed in the lowest extreme situation.
Check the existence of a chain between a conclusion and the case of the switch in the short circuit of contacts of the switch (in the high position of the lever of the walk of the system of brakes of parking).
One convinces of the lack of a chain between a conclusion and the case of the switch in the moment of the disconnection of contacts of the switch (in the lowered lever of the walk of the system of brakes of parking).
In the discrepancy of results of the check affirmed in top they substitute the switch or check his connection with "the weight".
The switch of a lamp of control of is not belted by me of fixed seat
Separate the capture of contact of the switch.
Check the existence of a chain between contacts of the switch.
In the seat hooked up the resistance of belt it will be the same as the infinity.
In not the fixed resistance of belt of seat it will be the same as the zero.
Of I do not belt lamp of control of fixed seat
In the included ignition they check the work of a lamp of control.
In the belt of seat hooked up the lamp of control it must not be burned.
In I do not belt of seat fixed the lamp of control it has to be burned.
