GF40.15-P-2005SK Detection of pressure loss, function
- with CODE (477) Tire pressure loss warning






Warning message





Reminder message

Function
The ESP and BAS control unit (N47-5) compares the 4 wheel rpm depending on the tire pressure. A reactivation is followed by a learning phase. In this phase the relative rolling circumferences of the tires are taught in in 6 different vehicle speed intervals. The tire pressure loss warning (RDW) is not active in this learn mode. The matching of the individual intervals takes 10 minutes/Interval. As of this point in time in each case the FL and RR ND FIR and RL tires are compared with each other.

Warning message
The tire pressure loss warning (RDW) has established while driving that the rolling circumferences of the wheels have changed relative to each other (considerable pressure loss in one tire).

Reminder message
This message is shown in the upper multifunction display (A1p13) after a red warning message, if the tire pressure loss warning (RDW) has not been reactivated afterwards.
