Method for controlling blower for cooling system of motor vehicle engine, involves releasing signals by engine controller by data cable for controlling blower at blower controller

摘要

The method involves releasing signals by an engine controller (24) by a data cable (22) for controlling the blower at the blower controller (18). The blower controller possesses an emergency operating function which is activated during breakdown of the data cable. The blower controller stays in connection with another sensor (26,28) whose signal is evaluated, so that the emergency operating function of the blower drive (16) is activated during breakdown of the data connection, if the measuring value of one of the sensor lies outside a specified value area.
