K183 UHF Short Range Low Energy Remote Control Access Transceiver

The K183 UHF Short Range Low Energy Remote Control Access Transceiver is the primary control module for the KeyPass system. It receives a constant B+ voltage and ground. The K183 UHF Short Range Low Energy Remote Control Access Transceiver communicates with the vehicle via Low Speed GMLAN and also with each B342 UHF Short Range Low Energy Control Access Transceiver via LIN. The K183 UHF Short Range Low Energy Remote Control Access Transceiver acts as the serial data master to the B342 UHF Short Range Low Energy Control Access Transceivers.

The K183 UHF Short Range Low Energy Remote Control Access Transceiver is typically located in a central location of the vehicle interior, often in the center console area. This is to ensure consistent wireless communication coverage of the driver seat area. The K183 UHF Short Range Low Energy Remote Control Access Transceiver takes information gathered from the B342 UHF Short Range Low Energy Control Access Transceivers, as well as information from it's own Bluetooth Low Energy transceiver, and relays these message to the OnStar enterprise center through the K73 Telematics Communication Interface Control Module.
