Circuit Description
When an ID code from the door electrical key oscillator RH matches an ID code from the smart key, the smart key ECU outputs a SEL2 signal (Lo when output) to the door electrical key oscillator RH, activates the touch sensor inside the outside door handle, and enters unlock standby condition. When the touch sensor is touched, the door electrical key oscillator sends a SENS signal (Lo when output) to the smart key ECU and the smart key ECU sends an unlock signal to each door lock.
