GF40.15-D-2004HH Detecting Rapid Pressure Loss, Function


Sudden pressure loss

Driving safety is no longer guaranteed if there is a rapid pressure loss. The driver is requested to stop the vehicle and to check the condition of the tires. It is the driver's responsibility to decide whether to continue the journey at low speed as far as the nearest workshop or whether an on-the-spot repair is necessary (use of TIREFIT or replacement of wheel). Rapid pressure loss is detected if a pressure loss of greater than or equal to 0.2 bar is detected within 60 s. While the vehicle is being driven, a warning message on the display (A1p1) of the instrument cluster (A1) informs the driver that a tire is defective.

The warning message is displayed permanently as long as circuit 15 is ON. When circuit 15 is set to ON again, the warning lamp is immediately actuated and the warning is given again after the vehicle has been driven for approx. 5 minutes.

With the operating condition "fast pressure loss", the tire concerned is highlighted on the display of the instrument cluster.

The RDK indicator lamp (A1e29) in the instrument cluster is actuated parallel to the "fast pressure loss". It goes out at reactivation or when the tire pressure monitor system has determined that the tire inflation pressure was corrected.
