March 4, 2024, John Gettel Systems Engineering Manager Aptiv 5725 Innovation Drive Troy, MI 48098 RE Declaration Letter RE: WCM-Tx1 FCC: L2C0091TR IC: 3432A-0091TR HVIN original (PV1): 1356 0618 / 1356 0619 / 1356 0620 / 1356 0621 HVIN updated (PV2): 1356 4197 / 1356 4198 / 1356 4199 / 1356 4200 The GM Wireless Charging Module WCM_tx1 has been updated from a PV1 to PV2 and we are seeking a FCC and ISED class 2 permissive change. These differences are;

1) HW Change - Antenna PCB Layers 3 & 4 swapped to improve PCB flatness / manufacturing quality No copper change Emissions and immunity evaluated by 3rd party: no change from PV1 to PV2 2) HW Change BOM change Tuning of NFC matching to compensate for slight change in NFC antenna impedance due to antenna board layer swap Populate C181 100uF capacitor on output of 5V DC converter BOM change only, no layout change Emissions and immunity evaluated by 3rd party: no change from PV1 to PV2 Aptiv Confidential 5725 Innovation Drive | Troy | Michigan | United States 4-Mar-2024 Page 1 of 2 3) HW Change New circuit New circuit added for receiver demodulation Emissions and immunity evaluated by 3rd party: no change from PV1 to PV2 4) HW Change New circuit New level shifter circuit to monitor QI_SW1 at micro Emissions and immunity evaluated by 3rd party: no change from PV1 to PV2 5) HW Change BOM change Component value changes to improve scaling of signals to be read by microcontroller ADC No layout change Emissions and immunity evaluated by 3rd party: no change from PV1 to PV2 EMC Comparison PV1 PV2 Background Based on the changes in hardware from PV1 to PV2, no emissions impact is expected Emission and immunity testing was performed by a 3rd party to verify they are equivalent in PV2 vs PV1 Sincerely, John Gettel Aptiv Confidential 5725 Innovation Drive | Troy | Michigan | United States 4-Mar-2024 Page 2 of 2

1356 4197 1356 4198, 1356 4199, 1356 4200 The funtional behavoir (RF, EMC, Qi, NFC) of all four hardware versions is identical The material of all four hardware versions, plastic resin, PCB and components, is eaxctly the same. The pinouts of all four hardware versions, is eaxctly the same. The differences between the hardware versions is associated with the mounting location within the vehicle, These differences are;

1) Housing Locating Notches 2. Each separate hardware version has a different housing locating notch which allows only the individual wireless chargers to be installed in a speci location within the vehicle. 2) Vehicle Hareness Connetor Keying 2. Each separate hardware version has a different vehicle connector key which allows only the wireless charger designed for that location to be connected tothe vehicle harness at that location Sincerely, John Gette!
