Back Door Entry Unlock Function does not Operate: Description

When an ID code from the door electrical key oscillator (back door) matches the ID code from the key, the certification ECU outputs an SEL signal (Lo when output) to the door electrical key oscillator (back door), activates the touch sensor located on the backside of the outside door handle, and enters unlock standby mode. When the touch sensor is touched, the door electrical key oscillator (back door) sends an SENS signal (Lo when output) to the certification ECU and the certification ECU sends an unlock signal to the back door lock.
