Hyundai Creta Tire Pressure Sensor

The compact-class crossover Hyundai Creta entered the market in 2014, the second name of the Hyundai ix25 model, Cantus. Already in the basic factory equipment, an individual tire pressure sensor hyundai creta and a TPMS active safety system are installed on the car, which monitors the inflation parameter of each tire, determines the load on the disc rim and displays information on the monitor.

The electronic unit is configured in such a way that data on the status of the main units of the car is transmitted to a mobile device, the driver can check the status of the car anywhere on his smartphone.

Features of the Hyundai Creta DSh

The Hyundai Creta tire pressure sensor is structurally a highly sensitive sensor that is mounted on the wheel. Using an electrical cable, the sensor is connected to the dashboard control panel to quickly alert the driver to critical pressure changes. The output of the second sensor is a radio signal that goes to the car's computer and the ABS active safety system. During the trip, the sensor informs the ECU about changes in pressure parameters and the general condition of the wheels. While stopped, the element is inactive.

The controller is mounted on a rubber or aluminum mount. The design allows you to independently change the controller without the use of special equipment. Hyundai tire pressure sensors have their own characteristics.

• Direct integration with the emergency light on the instrument monitor. If the tire pressure drops, a red question mark lights up in the instrument cluster.
• Activating the ABS system allows you to see the pressure parameter in each tire.
• All controllers are programmed at the factory for the following wheel sizes: for R16 tires, the allowable pressure is 2,3 Atm.; for size R17 - 2,5.
• Tire pressure depends on the air temperature, the driver must adjust the pressure according to the season.
• Possibility of reprogramming the readings of the sensors through the interface, depending on the diameter of the disc and the class of winter / summer tires.

The controller is configured not only to monitor the tire pressure parameter, but also warns the driver about such wheel failures:

• disassembly (consumption of fastening bolts);
• loss of tire elasticity or hernia;
• a malfunction may occur if the repaired wheel is used after a side cut;
• rubber overheating if non-original off-season tires are used;
• excessive load on the disk, occurs when the vehicle's load capacity limit is exceeded.

The regular DDSH in Cretu is part number 52933-C1100. The cost of original spare parts is quite high - from 2300 per set. The sensors transmit information via a radio signal at a frequency of 433 MHz, the kit includes a controller and a rubber mouthpiece. The node will require registration in the car's ECU through the "Auto Communication" procedure. The term of operation is 7 years.

As an alternative, drivers recommend choosing the original replica - the Schrader Generation5 repair kit, which is suitable for the Korean crossover. The cost of the part is 500 rubles, serial number 66743-68, the material of the nipple is aluminum. The manufacturer indicates a minimum product life of 3 years.

Causes of a malfunction of the DDSH on the Hyundai Creta

The wrong signal can be received on the dashboard not only in the case of a flat tire and a decrease in pressure parameters. The control unit is located on the drive, systematically experiences dynamic and mechanical loads, therefore it belongs to the vulnerable components of the car. Causes of failure of the pressure sensor.

• The body cracked and fell on the wheel. It occurs from a strong blow to the wheel when driving on a difficult road, after crossing obstacles at high speed, an accident.
• The increased load on the wheel when the axle is overloaded knocks down the sensor readings.
• Breakage in the wiring of the emergency lighting lamp. A thin wire comes from the controller, which can wear out, lose the density of the protective layer. The alarm signal will sound continuously in this case.
• Loss of contact at the terminals, oxidation of the contacts occurs when the parts are not cleaned of dirt, during the systematic operation of the car in the mud, in winter the contacts corrode after the ingress of salt reagents.
• ECU malfunction. With a fully functional sensor and good contacts, the control unit sends incorrect signals to the board.

In half of the cases when drivers notice a sensor malfunction, the reason is the use of non-original driver replicas that do not interact (do not correlate) with the ECU interface, the element is not registered in the vehicle's active safety system.

TPMS pressure monitoring system - features of work

Hyundai Creta is already in the base equipped with a TPMS system that promptly warns the driver about a critical decrease in tire pressure. The system signals a malfunction for a minute by flashing a red exclamation mark on the dashboard, after a minute the icon starts to burn constantly.

The TPMS indicator lights up not only when the pressure drops, but also after installing a new disc and at 20% when driving near power lines. Since it is impossible to find a single street in cities that is not equipped with electricity, many drivers are faced with the problem that the low pressure indicator is constantly on.

The second problem of the security system in Crete is the indicator that works when using a laptop in a car that works with the on-board network, when recharging the phone and other things. The system detects radio interference and correlates it as a fault. Therefore, many drivers want to disable the pressure sensor.

How to disable TMPS and remove the error

The driver is unlikely to be able to completely disable the TMPS monitoring system without special equipment. To do this, you must have a Hyundai scanner and software. To fix the error that appears after reinstalling the sensor, you need to reset the tire pressure and restart the computer. The ECU control unit must flash again, otherwise the indicator will systematically light up. How to temporarily disable TMPS step by step.

• Turn on the ignition, do not start the engine.
• To the left of the controller is the SET button, it must be attached.
• Wait for the beep.
• A buzzer notifies the driver that the display system is disabled.

It is recommended to restart the system after each sensor or wheel replacement, after changing seasons, when the indicator fails after using the gauges, etc.

In 30% of cases, after reinstalling the wheel while driving, the sensor starts to signal a malfunction. This is a normal situation, the system automatically adjusts after 20-30 km of the way the signal is cut off.

The driver is advised to check tire pressure every month in winter, once every 40 days in summer. Tire pressure is always checked on a cold tire. This means that the car has not been driven for the last 3 hours or has traveled less than 1,5 km during this time.

How to change DDSH to Creta

The replacement of the controller takes 15 minutes, after working with the pressure gauge, the pressure in the wheel is checked manually. The procedure for replacing the original TPMS sensor 52933c1100 is described below.

Remove the wheel in a safe manner. Disassemble the wheel, remove the tire. Remove the old sensor from the disk, install the new one in its usual place. Block the tire, inflate to the desired setting depending on the size. Register a new driver.

If the stock sensor is reinstalled to a similar one, then the Hyundai ECU is configured in such a way that it automatically recognizes and registers the driver. Therefore, when buying a set of control units, you do not need to write down their numbers, you can install the sensors separately. When removing and forging the wheel, it is important not to break the nipple head.

Changing tire pressure sensors on Crete is quite simple, the manufacturer has done everything possible so that the owner does not have any difficulties with synchronizing the element in the ECU and provides enough original repair kits and individual spare parts suitable for the model.
