FTM Flat Tire Monitor
The concept
The system does not measure the actual inflation pressure in the tires.
It detects a pressure loss in a tire by comparing the rotational speeds of the individual wheels while moving. In the event of a pressure loss, the diameter and therefore the rotational speed of the corresponding wheel change. This is detected and reported as a flat tire.
Functional requirements
The system must have been initialized when the tire inflation pressure was correct; otherwise, reliable signaling of a flat tire is not ensured. Initialize the system after each correction of the tire inflation pressure and after every tire or wheel change.
System limits
Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in advance.◄
A natural, even pressure loss in all four tires cannot be detected. Therefore, check the tire inflation pressure regularly.
The system could be delayed or malfunction in the following situations:
► When the system has not been initialized.
► When driving on a snowy or slippery road
surface.
► Sporty driving style: slip in the drive wheels,
high lateral acceleration.
► When driving with snow chains.
Status display
The current status of the Flat Tire Monitor can be displayed on the Control Display, e.g., whether or not the FTM is active.
1. "Vehicle Info"
2. "Vehicle status"
3. "Flat Tire Monitor"
The status is displayed.
Initialization
The initialization process adopts the set inflation tire pressures as reference values for the detection of a flat tire. Initialization is started by confirming the inflation pressures.
Do not initialize the system when driving with snow chains.
1. "Vehicle Info"
2. "Vehicle status"
3. "Reset"
4. Start the engine - do not drive away.
5. Start the initialization with "Reset".
6. Drive away.
The initialization is completed while driving, which can be interrupted at any time.
The initialization automatically continues when driving resumes.
