Back Door Entry Unlock Function does not Operate [09/2013 - ]: Description

When an ID code from the back door electrical key oscillator matches the ID code from the key, the certification ECU (ECU aggregation box assembly) outputs an SEL signal (Lo when output) to the back door electrical key oscillator, 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 back door electrical key oscillator sends an SENS signal (Lo when output) to the certification ECU (ECU aggregation box assembly) and the certification ECU (ECU aggregation box assembly) sends an unlock signal to the back door lock.
