The monitoring system of pressure of air in tires (RDC) *Action principle
The RDC system supervises pressure of air in tires of all four wheels and during movement. The system reports about considerable pressure drop in one or several tires.
In each wheel behind the gate there is a pressure sensor, the transmitter and the power supply. Through short intervals of time pressure measurement is made.
The obtained data are transferred on a radio channel. At a pressure deviation from norm periodicity of data transmission increases.
Near each wheel in a body there are aerials which accept signals from transmitters. The onboard processor processes arriving signals and reports about changes to the driver.
In order that the system "understood", what pressure is normal, it is necessary to check pressure in all four wheels, to compare to Specifications and if necessary to finish to norm. Then it is necessary to make active system.
1 Turn a key in situation 2.
2 Hold a key pressed until the control lamp on a control panel will not light up yellow light.
3 In some minutes after a start of motion the RDC system will remember the actual pressure of air in tires as a reference indicator by which it is necessary to be guided further.
This procedure should be repeated only after pumping of tires. In other cases the RDC system automatically joins after ignition key turn in situation 2 and operates at each trip.
At pressure drop
If pressure of air considerably falls after a while in tires (that in principle represents the normal phenomenon), the control lamp lights up yellow light.
Thereby you are offered to finish as soon as possible pressure in tires of your car to norm.
If after a while after pressure finishing to norm you are again offered to repeat this operation, it means that you incorrectly pumped up tires. Once again check pressure and compare its values to the values given in Specifications.
At a tire puncture
At a tire puncture with pressure loss the control lamp lights up red light. The sound signal in addition sounds.
In this case immediately lower speed up to a full stop of the car, avoiding thus sharp braking and sharp movements by a wheel. Replace the punctured wheel.
Provided on a case of a puncture of the tire compact колесо* (it can be used only temporarily) does not enter into the monitoring system of pressure of air in tires. Spare колесо* the identical size with other wheels established on the car, on the contrary, it is equipped with the necessary electronic means allowing a message control of pressure of air in it after installation instead of a defective wheel and activization of RDC system.
The RDC system cannot warn about a sudden rupture of a tire as a result of external influences.
For replacement of tires address on HUNDRED BMWs.
Other systems or devices which use the same radio frequency can negatively affect operability of RDC system.
During emergence of hindrances the control lamp burns with yellow light.
Yellow light of a lamp testifies also:
- about failure in system,
- about wheel installation without the corresponding electronics,
- about existence in the car together with spare колесом* also other wheels with electronics for RDC.
In such cases address on HUNDRED BMWs.
