Wireless Door Lock Tuner Circuit

WIRELESS DOOR LOCK TUNER CIRCUIT

CIRCUIT DESCRIPTION
The signal from the transmitter is input to the theft warning ECU (theft deterrent ECU) through the RDA line. The status of the RDA and RSSI lines are diagnosed by the theft warning ECU. If the wireless door lock control system fails, check for DTCs to confirm if the cause is the RDA and/or RSSI line.
