This is to be observed when checking the tire inflation pressure in workshop areas, especially in winter, when after a prolonged workshop visit the tire air temperature has reached room temperature. Example: Room air temperature = 36°F Ambient air temperature = 0°F The tire inflation pressure to be adjusted results from the specified tire inflation pressure + 0.2 bar.

information (manufacturer, direction of rotation, operating mode etc.). The data are conveyed via two-way radio to the TPM [RDK] control unit. In addition the TPM [RDK] control unit takes into account the outside temperature and the vehicle speed for the tire pressure determination. These data are provided via CAN from the instrument cluster. Warning indicator A warning is issued when a relevant loss of pressure has been detected in at least one of the tires. The driver receives the feedback over the tire pressure monitor warning lamp. The warning is issued without any position data. Manual restart The tire pressure monitor button in the cockpit switch panel can be used to reactivate the tire pressure to be monitored. When the tire pressure monitor button is pressed the tire pressure at that time, as long as it is in the permissible limits, is stored in the internal memory of the TPM [RDK] control unit and used as a reference pressure. A manual restart is displayed by the tire pressure monitor warning lamp flashing 3 times. The warning lamp request is sent over CAN from the TPM [RDK] control unit. A manual restart must be carried out for each change in tire inflation pressure, when replacing a wheel or a wheel sensor as well as when replacing the TPM [RDK] control unit.

The primary task of the TPM wheel sensors is to measure the pressure/temperature. The measuring range extends from p = 0 and 5.5 bar. While driving the tire pressure sensors transmit six data messages every t = 60 s. Absolute pressure, tire pressure temperature, wheel identifier and status information (manufacturer, direction of turning, operating mode) are transmitted in these data messages. The TPM [RDK] control unit (N88) receives the data telegrams and assigns (after a learning phase) the wheel identifier to the wheels fitted to the vehicle. As long as the TPM [RDK] control unit does not recognize the vehicle's own wheel identifier during initial commissioning, no fault message is displayed. After replacing a tire pressure sensor in each case the new tire pressure sensor is taught in and monitored with a new wheel identifier after driving for approx. t = 10 min. Design Each TPM wheel sensor is connected to the filling valve via a mounting bolt and forms an assembly unit with it. The assembly unit is attached to the rim flange using a counternut. The complete assembly unit has to be changed. A wheel sensor consists of the following components: Pressure sensor Temperature sensor High-frequency transmitter Sensor battery for power supply (service life approx. 10 years) BASIC KNOWLEDGE > OVERVIEW OF SYSTEM COMPONENTS FOR TIRE PRESSURE MONITOR (TPM), COMPONENT DESCRIPTION - GF40.15-P-9996MCU > MODEL 451.3/4 Instrument cluster, component description A1 GF54.30-P-6000MCU Wheel sensor, component description A69/1, A69/2, A69/3, A69/4 GF40.15-P-5126MCU Outside air temperature sender component description B14 GF83.57-P-4000MCC Component description for the SAM control unit N10/10 GF54.21-P-4157MCU Tire pressure monitor control unit, component description N88 GF40.15-P-5124MCU Cockpit switch group, component description S6/1 GF54.25-P-4300MCU Contents, function description, tire pressure monitor
