Entry System ECU FCC WARNING NOTICE 1.Preface This document describes the requirements and operation of the Passive Entry System. However, this document is especially for the Entry system ECU (acronym for Electric Control Unit) and the FOB. The FOB consists the following functionality for passive access and active access: • Door unlocking / locking (however, only for request by means of switch operation) • Trunk open (however, only for request by means of switch operation) • LF decoding • RF encoding • Communication data encryption (cryptograph, anti-collision, rolling code and stuff) And the entry system ECU consists of the following functionality: • Door unlocking / locking • Trunk open • Engine start (/ stop) • LF encoding • RF encoding • Communication data encryption (cryptograph, anti-collision, rolling code and stuff) • LF antenna unit control • Communication with the node ECUs connected to the body bus (e.g. CAN, J1850, customer dependent bus) As a further function, both the FOB and the entry system ECU provides the following function: • Learning mode for programming the manufacturing data and stuff • Data locking and password protection • Diagnostic (based upon ISO9141 if required) 2.Passsive Accsess Entry Functionality A handle sw located on, for example the door handles, mirrors and trunk lid will be used for proximity check if user is in neighborhood of the vehicle. The switch input will trigger for unlocking and open the doors and trunk. Figure 1 2.1.Door Unlocking • User pushes door handle sw. • ECU sends LF-challenge via exterior antenna. • FOB sends RF-response to the ECU. • Door unlocking status is engaged. • Doors are opened. Figure 2 Door Handle SW LF RF FOB 2.2.Engine Start • User operates the engine start knob. • ECU sends LF-challenge via interior antenna. • FOB sends RF-response to the ECU. • Immobilizer ECU receives and authorize the response. • Engine controller ECU receives the authorization for engine strat. • Start the engine. Figure 3 2.3.Engine Stop • User operates the engine stop knob. • ECU communicates with the other ECU for engine start request. • Engine controller ECU receives the request. • Stop the engine Figure 4 LF RF FOB 2.4.Door Locking (Push switch) • User closes the door and pushes the switch (sensing of door locking switch). • ECU sends LF-challenge via exterior antenna. • FOB sends RF-response to the ECU. • Door locking status is engaged. • Doors are locked. • (Indicates the door locking status by means of Flasher / Buzzer or stuff) Figure 5 3.Active Access Entry Functionality 3.1.Door Unlocking Same functionality as the current one. 3.2.Engine Start This function does not effect on the active entry system. 3.3.Engine Stop This function does not have influence on the active entry system. 3.4.Door Locking Same functionality as the current one. 3.5.Trunk Open Same functionality as the current one. 4.Entry System Options 4.1.System Schematic 4.2.Modules 4.2.1.FOB ECU 4.2.2.Entry System ECU OTHER ECUS LF (>2Kbps) Local Bus ECUECUECU Body Bus ENTRY SYSTEM ECU FOB 125kHz RF (>4Kbps) 315MHz FOB RF Amp LF Amp ASIC Z X Y Lock Unlock Trunk Emergency key (Transponder) 125kHz 315MHz ENTRY SYSTEM ECU MCU Dr Door handle As Door handle Trunk Push knob (Engine start knob) Body Bus Local Bus LF Exciter LF Exciter LF Exciter LF Exciter Room1 Dr As Trunk 125kHz Dr : Driver Door Antenna As : Assist Door Antenna Trunk : Bumper Antenna Exterior Antenna Room1: Console Antenna Room2: Inst.

Modification of EUT : No modification by the test lab. Model: TWD1U633 (referred to as the EUT in this report) is a Control Unit of Passive Entry System. The Passive Entry System is a system which locks, unlocks and can start engine only with the intelligent-key of the vehicle. Equipment type : Transceiver Operation temperature range : -30 ~ +80 deg. C. Other clock frequency : 32.768kHz, 16MHz, 65.14MHz (Crystal) Emission designation : A1D Tx section Frequency of operation : 125kHz Modulation : Amplitude Antenna type : External Bar antenna Rx section Frequency of operation : 315MHz Intermediate frequency : 10.7MHz Local frequency : 325.7MHz Type of receiver : Super Heterodyne Antenna type : Internal Bar antenna FCC Part15.31 (e) The power supply of the EUT is transformed to DC5.0V and provides stable voltage, DC5.0V constantly to Radio part. Therefore, the EUT complies with the power supply regulation. FCC Part15.111 (b) The receiving antenna is installed inside the EUT and cannot be removed. Therefore, the EUT complies with the requirement. FCC Part15.203 Antenna requirement It is impossible for users to replace the antenna because the antenna is a set with EUT and installed outside of the EUT inside the vehicle.
