Entry System ECU FCC WARNING NOTICE ALPS ELECTRIC Co., LTD 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 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 • Trunk 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) ALPS ELECTRIC Co., LTD 2.Passsive Accsess Entry Functionality A proximity sensor 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 pull / touch the door handle (sensing of door handle switch). • ECU sends LF-challenge via exterior antenna. • FOB sends RF-response to the ECU. • Door unlocking status is engaged. • Doors are opened. Figure 2 Proximity sensor LF RF FOB ALPS ELECTRIC Co., LTD 2.2.Engine Start • User pushes / operate the engine start button / 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 pushes / operate the engine stop button / 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 ALPS ELECTRIC Co., LTD 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 ALPS ELECTRIC Co., LTD 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 influencei on the active entry system. 3.4.Door Locking Same functionality as the current one.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 June 13, 2003 RE: FCC ID: NHVWBU613 Attention: Yukari Ito I have a few comments on this Application. 1. Please remove the cover shown in the internal photo called “Side A” and show the circuit board underneath. 2. Under no circumstances can a harmonic emission be greater than the fundamental for part 15 devices. In the test report you show a peak reading of the fundamental as being 45dBuV/m. In the table you also show a harmonic at 630 MHz having a QP reading of 35.6dBuV. If the peak reading is over the peak reading of the fundamental, the device fails. Since this number is within the probable expectation of a QP of a signal higher than 45dB, please provide the peak reading of 630MHz or otherwise please verify that the peak signals of the harmonics are not greater than that of the fundamental. 3. In your manual you use the term “Communication data encryption”. Please note that part 15.231 devices may not transmit DATA. Please explain what this term means in relation to the device. Please provide evidence that this device conforms to 15.231(a). Dennis Ward mailto:[email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information may result in application termination. Correspondence should be considered part of the permanent submission and may be viewed from the Internet after a Grant of Equipment Authorization is issued.

June 20, 2003 RE: TOHOKU ALPS CO., LTD. FCC ID: NHVWBU613 Dear Mr. Dennis Ward, Regarding the above referenced application, please find our reply to the comments dated June 13, 2003: 1) Please see the submitted “Revised Internal Photos.” 2) Please see the submitted data of the peak reading. The peak signals of the harmonics are not greater than that of the fundamental. 3) Tohoku Alps confirmed that the word, “data” of “Communication data encryption” in users manual means the control signal. We hope the above reply is satisfactory. If any problems, please let us know. Best regards, Yukari Ito (Ms.) UL Apex Co., Ltd.
