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) 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 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) Confidential 2.Passsive Accsess Entry Functionality A handle sw located on, for example the door handles and mirrors 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 Door Handle SW 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. RF LF FOB Figure 2 Confidential 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. FOB RF LF 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 Conf…

Type of Equipment : Passive Entry System (Control Unit) Model No. : TWD1U750 Serial No. : 173938 Rating : DC12V (Car Battery) Country of Manufacture : Japan Receipt Date of Sample : February 9, 2007 Condition of EUT : Production prototype (Not for sale: This sample is equivalent to mass-produced items.) Modification of EUT : No modification by the test lab. 2.2 Product Description Model: TWD1U750 (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 Clock frequency : 16MHz (Main), 32.768kHz (Sub), 65.14MHz (Crystal) Operation temperature range : -30 to +80 deg.C. <Transmitter> Frequency of operation : 125kHz Type of modulation : AM Antenna type : External bar Antenna connector type : None ITU code : A1D <Receiver> Frequency of operation : 315MHz Intermediate frequency : 10.7MHz Local frequency : 325.7MHz Type of receiver : Super heterodyne Antenna type : Internal bar Antenna connector type : None *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 Part15.203 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. Therefore, the EUT complies with the antenna requirement. FCC ID : CWTWDU750 Test report No. : 27FE0255-YK-A Page : 4 of 18 Issued date : February 23, 2007 UL Apex Co., Ltd.
