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, RDA2, RSS1 and RSS2 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, RDA2, RSS1 and/or RSS2 line.
