Operation of the WCPM2
The Stellantis Wireless Charging Pad Module 2 (WCPM2) performs (2) separate functions First, the unit facilitates NFC communication with a smartphone/NFC card and the vehicle’s SPAAK (SmartPhone As A Key) module. Second, the unit will wireless charge a smartphone that is 1.3 Qi compliant, BPP (Baseline Power Profile) supporting transfer of up to about 5 W and an EPP (Extended Power Profile) supporting transfer of up to about 15 W of power.
LED Indicator Operation:

Solid Green: Fully Charged (if supported by Smartphone)
Solid Blue: Charging
Blinking Red: Internal fault/Foreign Object Detect
2 Modes: Daytime (100% intensity) and Nighttime (10% intensity).
