METHOD FOR CHECKING THE OPERATION OF A PSI5 RECEPTION UNIT IN A MOTOR VEHICLE CONTROLLER, AND CORRESPONDING PSI5 RECEPTION UNIT.

摘要

A method for checking the operation of a PSI5 reception unit (1) in a motor vehicle controller is presented, wherein the PSI5 reception unit (1) receives signals (SENS) from a connected PSI5‑compliant PSI5 transmission unit (2), wherein a check signal transmission unit (6) is provided and this check signal transmission unit (6) sends a prescribed check signal (Test) to the PSI5 reception unit (1) at prescribed check times at which no signal (SENS) can be expected from the PSI5 transmission unit (2), in particular - together with the sending of one or more synchronization pulses (SYNC) to the transmission unit (2) - the check signal transmission unit (6) sends the check signal (Test) in this defined period.
