Tire pressure sensor Hyundai Solaris

How does the Solaris tire pressure sensor work?

The principle of operation of this system is based on the fact that a flat tire has a smaller radius and therefore travels a shorter distance per revolution than an impeller. The ABS wheel speed sensors measure the distance traveled by each tire in one revolution.

How to reset Solaris low tire pressure error?

It's simple: turn on the ignition and press the initialization button on the sensor, hold it for a few seconds and voila. Setup completed.

What does the SET button on Solaris mean?

This button is responsible for setting the basic values ​​​​for the indirect tire pressure control system.

How to view the pressure in the Solaris tires?

The recommended tire pressure for your Hyundai Solaris is indicated in the owner's manual, and is also duplicated on the plate (on the gas tank cap, on the driver's door pillar or on the glove box lid).

What does the SET button on the remote mean?

There are two LEDs on the remote control to indicate pressure and operating modes. ... Press the "SET" button and hold it for 2-3 seconds until the red LED on the remote control lights up brightly; this means the remote control is ready to learn.

What is the SET button for?

The automatic fault monitoring system monitors the operation of vehicle components and certain functions. With the ignition on and while driving, the system works continuously. By pressing the SET button with the ignition on, you can manually start the test process.

How does the tire pressure monitoring system work?

The sensors are mounted on the nozzles of the car wheels, they measure the pressure and air temperature in the tire and transmit information about the pressure value via radio to the display. When tire pressure changes, the system transmits information with sound signals and displays it on the screen.

How is the tire pressure sensor installed?

To install mechanical sensors, unscrew the protective cap on the booster valve and screw the sensor into place. To install the electronic sensor, it is necessary to remove and disassemble the wheel, and then remove the regular inflation valve. This operation can only be performed on wheels with tubeless tyres.

Indirect Tire Pressure Monitoring System (TPMS)

TPMS is a device that notifies the driver if the tire pressure is insufficient for safety reasons. Indirect TPMS detects tire pressure by using the ESC wheel speed signal to control wheel radius and tire stiffness.

The system includes a HECU that controls the functions, four wheel speed sensors each mounted on a respective axle, a low pressure warning light and a SET button used to reset the system before a tire change.

To ensure normal operation of the system, it is necessary to reset the system in accordance with established procedures, and the current tire pressure must be remembered during programming.

The TPMS learning process will be completed after the vehicle has been driven for approximately 30 minutes between 25 and 120 km/h after the reset. Programming status is available for checking with diagnostic equipment.

Once TPMS programming is complete, the system will automatically turn on a warning light on the instrument panel to inform the driver that one or more tires have detected low pressure.

Also, the control lamp will light up in the event of a system malfunction.

Below are the different indicators for each event:

The warning light flashes rapidly for 3 seconds and then goes out for 3 seconds. The indicator light flashes for 4 seconds and then goes out normal pressure in the following situations. In this case, stop the car for at least 3 hours to let the tires cool down, then adjust the air pressure in all tires to the desired value and reset the TPMS. When the TPMS was reset, the pressure was overpressured, The pressure increased as a result of an increase in internal temperature due to long-term driving or The TPMS was not reset when it should be, or the reset procedure was not performed correctly.

What pressure should be in Hyundai Solaris tires

The pressure in Hyundai Solaris tires on 15 spokes is exactly the same as on the R16. In the first generation models, the manufacturer allocated 2,2 bar (32 psi, 220 kPa) to the front and rear wheels. The manufacturer considers it necessary to periodically (once a month) check this parameter even on the spare wheel. It is carried out on cold wheels: the car must not be in motion for at least three hours or drive no more than 1,6 km.

Solaris 2017 came out in 2. The factory recommended increasing the inflation pressure to 2,3 bar (33 psi, 230 kPa). On the compact rear wheel, it was 4,2 bar. (60 psi, 420 kPa).

Slightly increased the volume of the trunk and the weight of the car. Changed wheel nut tightening torque. It increased from 9-11 kgf m to 11-13 kgf m. Also, the instruction was supplemented with recommendations for adjusting this parameter. In anticipation of a cold snap, an increase of 20 kPa (0,2 atmospheres) is allowed, and before traveling to mountainous areas, a drop in atmospheric pressure should be taken into account (if necessary, it will not hurt to pump up).

The standards can be found on a plate, usually located on the driver's side door. Its observance is a guarantee of fuel economy, handling and safety.

A sharp decrease in pressure on the slopes leads to overheating of the tire, its delamination and failure. This could lead to an accident.

A flat tire increases rolling resistance, increasing wear and fuel consumption. An over-inflated tire is more sensitive to road terrain and has a higher risk of damage.

On a flat road, it is advisable to inflate the tires more than on a country road, but not too much. You can add 0,2 bar for better rocking, no more. Tread wear in the middle at high pressure and on the sides at low pressure has not been canceled. If you deviate from the factory recommendations, the life of the tire is clearly reduced. An increase in traction as a result of an increase in the contact patch is relevant only with a very strong deterioration in the quality of the road in extreme situations (you need to get out of a pile of snow or mud). Increased fuel consumption is guaranteed. In other cases, it is irrational and inconvenient.

Solaris R15 tire pressure in winter and summer

The manufacturer does not plan to change the gear in winter, so the usual 2,2 atmospheres will do, if the roads are bad, then 2 bars will be the maximum.

According to some motorists, it should be slightly lowered on all wheels evenly or only on the rear ones.

Solaris Tire Pressure Monitoring System

The model uses an indirect control configuration. Unlike a direct acting system, it does not measure pressure in each tire, but detects dangerous misalignment based on wheel speed.

When the air pressure in the tire drops, the wheel flexes more and the tire rotates at a smaller radius. This means that in order to cover the same distance as the repaired ramp, it must rotate at a higher frequency. The wheels of the car are equipped with frequency sensors. The ABS has corresponding extensions that record their readings and compare them with control values.

Being simple and inexpensive, TPMS is characterized by poor measurement accuracy. It only warns the driver of a dangerous pressure drop. The technical specifications of the car do not indicate the critical amount of air compression drop and the speed required for the system to work. The unit cannot determine the pressure drop in a stopped vehicle.

There is a low pressure gauge on the dash coupled with a TPMS malfunction. Another icon is on the LCD screen. The reset button "SET" is installed on the control panel to the left of the controller.

How to reset the low pressure error in Solaris ramps: what to do

If the pressure icon lights up and the ramps show a low pumping message, you should stop quickly, avoiding sudden maneuvers and changes in speed. Next, you need to check the actual pressure. Visual inspection should not be relied upon. Use a manometer. Often a wheel with a slight bulge will appear to be partially flat, and a tire with a strong sidewall will not sag too much when the pressure drops.

If the malfunction is confirmed, it must be eliminated by inflating, repairing or replacing the wheel. Then reboot the system.

If the steering wheel is normal, you also need to reset the system. This is done with the "SET" button after bringing the pressure to normal, and in strict accordance with the instruction manual, which is instructional documentation for the driver. It also lists the situations in which it is necessary to perform this procedure. It needs to be studied in detail.
