Circuit/System Description

The remote control door lock receiver (RCDLR) receives a radio frequency (RF) transmission from each tire pressure sensor. Each sensors RF transmission contains its own unique identification (ID) code that must be learned into the RCDLR memory. Once all 4 IDs have been learned and vehicle speed is 25 mph or greater, the RCDLR continuously compares IDs in received transmission to its learned IDs to determine if all 4 sensors are present.
