In this document the device is referenced as "key", even if the mechanical backup key might be separated form it. For an overview of the electrical function blocks, please see the document "Block diagram of Nissan D – Plateform i – key". Operating modes The key has three main operating modes which differ in the regard of signals transmitted on the RF. As there is • · Immobilizer transponder mode • · Remote key functionality • · Passive key functionality Immobilizer Transponder mode When the key is operating as an immobilizer transponder, communication is done over a "contact less interface" depending on strong magn etic coupling. The transponder is the passive side of the link and there is no RF transmission from it involved in any aspect. Remote key functionality This mode refers to the use of the key as a remote control to initiate actions on vehicle side such as open or close door latches and such alike. RF transmission always depends on a user activating a button on the key. Duration of the button press influences the amount of telegrams sent on the RF channel. Short Button press: SIEMENS AG SV C BC P2 Siemens VDO Automotive FCC ID:KR55WK48903 IC:267T-5WK48903 I:\POSTZULA\NISSAN\D-PF_I-Key\Technische_Doku_doc\Functional_Description_DPF-I-Key.doc Page 3 of 4 A valid but short button press, as indicated in the upper half of the above diagram, results in a minimum number of RF telegrams to be sent. This is visualized in the lower half of the diagram. Long button press: If the button press duration extents the time required for sending the minimum amount of RF telegrams, additional ones are transmitted until the button is released or a timeout of 25s is reached. This timeout prevents unintended transmissions over extended time period s in case of a stuck button. Passive key functionality For passive key operation no user action on key side is required. The trigger is delivered from the vehicle via an LF data telegram. Upon reception of a valid LF message, the key responds with two telegrams on RF side while the inter telegram timing in this mode depends on key configuration data (sort of time slot concept). RF parameters For all RF transmission the following parameters apply: US variant JP variant Center frequency 315 MHz 314.85 MHz Frequency accurracy ± 30 kHz ± 20 kHz Frequency deviation ± 25 kHz nominal ± 25 kHz nominal RF modulation FSK FSK RF frame baudrate 2 kBd 2 kBd Data coding Manchester Manchester Variants 5WK48902 Japan Version 315 MHz LP 5WK48903 US Version 315 MHz 5WK48906 US Version 315 MHz, same as 5WK48903 SIEMENS AG SV C BC P2 Siemens VDO Automotive FCC ID:KR55WK48903 IC:267T-5WK48903 I:\POSTZULA\NISSAN\D-PF_I-Key\Technische_Doku_doc\Functional_Description_DPF-I-Key.doc Page 4 of 4 only different Logo at device Label Design Siemens VDO 5WK48903 FCC ID:KR55WK48903 IC:267T-5WK48903 Warning Statement: NOTE This device complies with part 15 of the FCC Rules and RSS-210.
