Keyless Entry System on-Board Diagnosis

^ There are two functions for the keyless entry system on-board diagnosis (OBD). OBD function 1 tells the keyless unit and CPU to activate the power door lock and trunk lid opener systems without the transmitter. OBD function 2 monitors a keyless entry demand signal sent from the transmitter and used inside the keyless unit. OBD function 2 diagnoses the transmitter, integrated antenna and the keyless unit.
