Liepa the Power of Attorney is on file and can be provided when so requested. Re: Certification for Delphi GMT 365 Immobilizer Model: GMT 365 FCC ID: L2C0020TR IC: 3432A-0020TR REQUEST FOR CONFIDENTIALITY Pursuant to 47 CRF 0.459, Delphi Delco requests that a part of the subject application be held confidential. This comprises Exhibits (5) Schematics (10) Parts List (Part of Exhibit only) Delphi Delco has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. If there are any questions regarding this request, please contact me at the above address or call 734-483-4211, fax 734-647-2106 or e-mail [email protected]. Sincerely, Valdis V.

September 13, 2003 RE: Delphi Automotive Systems FCC ID: L2C0020TR The following is in response to comments made on the above referenced Application. 1) Please provide the response frequency of the transponder. The transponder is a passive device, embedded in the key and is thus not subject to regulations. However, it responds at nearly the same frequency as the LF initiator 131 kHz ±2 kHz depending on tuning. 2) The parts list provided appears to contain 2 different parts lists. Please explain. The second parts list was mistakenly included. It was a listing for the parts included in the test box, and is not part of the DUT. The exhibit has been corrected and a new copy has been uploaded. 3) The calculation in section 6.1 doesn't appear correct. Please verify. There was a typographical error in section 6.1 of the test report. It has been corrected and a new exhibit has been uploaded.

MY2005 GMX 365 Passkey 3 Reader/Exciter PAGE: 2 of 3 * DELPHI DELCO ELECTRONICS SYSTEMS Confidential * PRODUCT OVERVIEW The Passkey III Reader/Exciter module is part of a vehicle immobilization system intended to prevent amateur theft. The module, through its coil antenna, energizes a transponder embedded in the head of the ignition key and reads the unique security code from the transponder. The module sends the security code it receives from the transponder to a Controller Module for authentication. ELECTRICAL SPECIFICATIONS/Characteristics The Passkey III Reader/Exciter module consists of the following functional block: 1. Closed-Loop Drive/Oscillator 2. Resonant L-C 3. Coil Drive Wave Shaping 4. AM detector 5. Data Filtering/Amplification The Reader/Exciter (R/E) module receives power from the vehicle body controller module when vehicle ignition switch is activated. Once power is delivered to the R/E module, a current- controlled oscillator is activated with nominal frequency set to 131 kHz. The square wave signal generated by the oscillator is fed to a wave shaping stage and drives a series resonant RLC nominally tuned to 131 kHz (with lock cylinder effect). The inductor or the coil antenna is a 97- turn, 33 gauge wire wound with inside diameter of approximately 34.38mm. The coil antenna is fitted and positioned around the vehicle ignition lock cylinder. The signal of the oscillator driving the series RLC is fed into a phase detector along with the sinusoidal resonant voltage formed by series RLC. The difference of phase between the oscillators drive signal and the sinusoidal resonant signal is converted into current sink or source to the current controlled oscillator. It effectively forms a closed loop system whereby the oscillator frequency tracks the resonant frequency of the series RLC. The current generated in the coil antenna produces a magnetic field around the coil, which extends to couple to a transponder in the key. The coupled energy from the R/E module energizes the transponder and in turn transponder modulates the magnetic field in accordance to the security code at a rate of 2 kHz. The modulation of the magnetic field by the transponder produces a small amplitude modulation on the series RLC resonant signal. This signal is fed into an AM detector that removes the 131 kHz carrier and retains the 2 kHz security code. MY2005 GMX 365 Passkey 3 Reader/Exciter PAGE: 3 of 3 * DELPHI DELCO ELECTRONICS SYSTEMS Confidential * The low level 2 kHz security code is then low-pass filtered and amplified to result in a digital pulse train that contains the security code. The signal is send out via the data out pin to the vehicle body controller for authentication. Mini Internal Mechanization.
