SYSTEM DESCRIPTION
WIRELESS DOOR LOCK CONTROL SYSTEM
The wireless door lock control system can be used to lock and unlock all doors from a distance. The system is controlled by an electrical key transmitter sub-assembly which sends radio waves to the electrical key and tire pressure monitoring system receiver assembly. The certification ECU (smart key ECU assembly) performs an ID code identification process and operates the door lock control.
MULTI CHANNEL FUNCTION
The wireless door lock control system has a multi channel function. Each time the switch on the electrical key transmitter sub-assembly is pressed, the channel is switched alternately between 2 different frequencies and the signal is sent to the electrical key and tire pressure monitoring system receiver assembly.
