Continental Automotive GmbH B&S S2 Thierry RASPAUD Josef Lohr -1- 2011-06-20 User Manual / Functional Description of the Continental Radio Frequency Transmitter Type S180144011 S180144014 S180144015 Functional description of Nissan DPF I – key 3rd Bundle This document gives an overview of the different device operation modes and the RF transmissions performance of the key. In this document the device is referenced as "key", even if the mechanical backup key might be separated from it.
Continental Automotive GmbH B&S S2 Thierry RASPAUD Josef Lohr -2- 2011-06-20 1. Operating modes The key has three main operating modes which differ regarding of the signal transmitting with the RF:  · Immo Immobilizer transponder mode  · RKE Remote key functionality  · PASE Passive key functionality  · RES Remote engine start functionality Immobilizer Transponder mode When 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 functionality This 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: A short valid button pressing results a sending of the minimum number of the RF telegrams, as showed on the diagram.
Continental Automotive GmbH B&S S2 Thierry RASPAUD Josef Lohr -3- 2011-06-20 Long button press: If the duration of the button pressing extents the time required for transmitting the minimum amount of RF telegrams, additional telegrams will be sent until the button is released or a timeout of 10s is reached. This timeout function prevents the unintended transmission over the extended time periods in case of a button was fixed. Passive key functionality For 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). Remote engine start functionality This mode refers to use the key as a remote control unit to initiate actions on the vehicle such as start and stop engine. 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. In this mode, RF output power is higher than RKE mode. 2. Block diagram
