In this document the device is referenced as "key", even if the mechanical backup key might be separated from it.For an overview of the electrical function blocks, please see the document "Block Diagram ofNissan DPF I –key 2nd Bundle".1. Operating modesThe key has three main operating modes which differ regarding of the signal transmitting with theRF:•· Immo Immobilizer transponder mode•· RKE Remote key functionality•· PASE Passive key functionalityImmobilizer Transponder modeWhen the key is operating as an immobilizer transponder, the communication is done via a "contact less interface" depending on a magnetic coupling. The transponder is the passive side of the link and there is no RF transmission from it involved in any aspect.Remote key functionalityThis mode refers to use the key as a remote control unit to initiate actions on the vehicle such as open or close door latches. RF transmission depends on a user activating (a button pressing) on the key. During the button pressing the amount of telegrams are sent on the RF channel.Short button press:

This timeout function prevents the unintended transmission over the extended time periods in case of a button was fixed.Passive key functionalityFor passive key operation no user action on the key side is required. The trigger is delivered by the vehicle via an LF data telegram. When the key receive a valid LF message, it responds with two RF telegrams and the inter telegram timing in this mode depends on the key configuration data (sort of time slot concept).2.
