Wheel-speed sensor failure
If no signal is received from one of the wheel-speed sensors, the RPA will switch to "inactive" mode after approximately 2 minutes. The RPA indicator and warning light lights up yellow. The fault is indicated with a check control message.
A fault is recorded in the fault memory of the RPA control unit. If the RPA is integrated into the DSC Dynamic Stability Control, a fault will be recorded in the DSC control unit.
Read off status of initialization phase
The status of the initialization phase can be displayed in the service functions for the control unit concerned (e.g. DSC control unit).
If a claim is entered due to the RPA not giving a warning on time, the status of the initialization phase can be displayed in service. The time of the last initialization is also displayed in service.
A warning can only be emitted in the speed range that have been calibrated by at least 67%.
