Hier noch die Anleitung für den Anlernprozess - automatisch ohne Eingriff!
Because of the requirement for different pressure targets and thresholds for the front and rear tires, the CJB can identify the location of the tires on the vehicle, and assign a received tire pressure sensor identification to a specific position on the vehicle (i.e. FL (front left), FR (front right), RL (rear left) or RR (rear right)).
Tire location is performed automatically by the CJB using an auto-location function. This function requires no manual intervention by the driver. The CJB can automatically learn the position of tires on the vehicle if the tire pressure sensors or their positions are changed on the vehicle.
The tire learn and location process is ready to commence when the vehicle has been stationary or is traveling at less than 12 mph (20 km/h) for 15 minutes. This is known as 'parking mode'. The learn/locate process requires the vehicle to be driven at speeds of more than 12 mph (20 km/h) for 15 minutes. If the vehicle speed reduces to below 12 mph (20 km/h), the learn process timer is suspended until the vehicle speed increases to more than 12 mph (20 km/h), after which time the timer is resumed. If the vehicle speed remains below 12 mph (20 km/h) for more than 15 minutes, the timer is set to zero and process starts again.
The CJB can automatically detect, under all operating conditions, the following:
- one or more tire pressure sensors have been replaced
- one or more tire pressure sensor identifications are missing
- one or more ‘alien’ identifications are being received, i.e. the CJB can reject identifications from tire pressure sensors that do not belong to the vehicle
- the spare tire and one of the tires in use on the vehicle have exchanged position on the vehicle.
If the tire pressure sensors fitted to the running wheels (not the spare) are changed, the CJB can learn the new sensor identifications automatically. The learn function requires no manual intervention by the driver.
If a new sensor is fitted to the spare tire it must have its identification code programmed into the CJB using a Land Rover approved diagnostic system, or used on the vehicle as a 'running' wheel and the vehicle driven for 15 minutes at more than 12.5 mph (20 km/h).
