The remote control door lock receiver is located under the left side of the instrument panel. The remote control door lock receiver performs the functions of interpreting the signals from the transmitter and relaying the information to the multifunction alarm module. The remote control door lock receiver does not directly control any functions but is an interpreter for the transmitter to tell the multifunction alarm what function is requested. The module is able to differentiate up to 4 transmitters, and must be programmed to accept signals from each transmitter.

The remote control door lock receiver receives battery voltage from the DOME fuse through Junction Block 1 to terminal 8 of the receiver connector.

The receiver receives ground from G200 to terminal 1 of the receiver connector.

The remote control door lock receiver sends LOCK and UNLOCK output signals to the multifunction alarm through the splices from the door lock switch to the multifunction alarm.
