Zusammenfassung:The present disclosure generally relates to a method for monitoring the performance of a blower motor for a blower unit positioned in a vehicle. The method may include: diagnosing the motor based on predefined criteria and one or more physical parameters sensed by one or more sensors; identifying a performance mode from among a plurality of modes based on the diagnosis, where the plurality of modes are predefined; determining a mode message based on a signal code protocol, where the mode message is indicative of the performance mode identified and the signal code protocol associates each of the plurality of modes with a different coded signal; and transmitting a diagnostic signal that includes the mode message to a climate control module located in the vehicle separate from the motor.
