Circuit/System Description

The remote control door lock receiver (RCDLR) receives a radio frequency (RF) transmission from each tire pressure sensor. Each sensor 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 greater than 40 kph (25 mph), the RCDLR continuously compares IDs in received transmission to its learned IDs to determine if all 4 sensors are present. If the RCDLR detects a low tire pressure condition or a malfunction in the system, it will send a serial data message to the instrument panel cluster (IPC) requesting tire pressure monitor indicator icon illumination and to display a data message on the driver information center (DIC), if equipped.
