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) Document No. Title Page 5AX000XX00 Product Specification Background Passive Entry System FORMAT NO. FIRMWARE_A(VER 0.01) 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.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 October 14, 2002 RE: FCC ID: NHVWBU61 Attention: Mr.Makoto Kosaka / Ms.Yukie Koyama I have a few comments on this Application. 1 The following documents contain non-English fonts and cannot be read by the FCC server: Schematics, Label drawing and location, Test report. Please provide documents that do not contain non-English fonts. 2 Please provide Internal photos of the device. The file listed as internal photos cannot be read and is not recognized by the ATCB server. 3 On page 14 of the report, there appears to be 2 carriers separated by 90 kHz shown in the bandwidth plot. Please explain. 4 Please note that pulse width modulation duty cycle for devices whose transmission exceeds 0.1 sec is determined by the alternative method. “In cases where the pulse train exceeds 0.1 seconds, the measured field strength shall be determined from the average absolute voltage during a 0.1 second interval during which the field strength is at its maximum value.” Please note that in your calculation you referenced 189us to 391us, not to the required 100ms. While the device may be a 50% duty cycle device, the references need to be in accordance with Part 15. Since the device appears to have a pulse train longer than 100ms, please shown compliance using 100ms, not 391us. This would be the total on time to total time. 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. Please do not respond to this correspondence using the email reply button. In order for your response to be processed expeditiously, you must submit your documents through the AmericanTCB.com website. Also, please note that partial responses increase processing time and should not be submitted. Any questions about the content of this correspondence should be directed to the sender.

Subject: Re: 10-14, 02 NHVWBU61 ATCB Comments..PDF Date: Tue, 15 Oct 2002 15:23:37 +0900 From: [email protected] To: [email protected] CC: [email protected] Dear Dennis, Thank you very much for your contact on the above application. I make a reply as follow. 1. As for the Schematics and Label drawing & location, I re-uploaded them through your website. Please check them. As for the testreport, we think this file doesn't contain non-English fonts because we can open this file and see all pages by our English acrobat. Could you check this again? If there is any pages of non-English fonts, please let me know the applicable pages. 2. We uploaded the revised Internal photos. Please check it. 3. Since the modulation of the Hand Unit <NHVWBU61> is FSK <Frequency shift keying, we observed the waveform as the submitted testreport. However, since we wrote only Frequency on the page 3, we modified "Frequency" to "Frequency shift keying". Please replace original page 3 to "revise Page 3". 4. We added the applicable data and uploaded it. Please see the "add A3-1". Thanks.
