**APTIV WCM_tx1 Wireless Charging Module User Manual
**
Purpose| The Wireless Charging Module version WCM_tx1, Variant A (forward compatible form factor) charges consumer electronics devices wirelessly by supplying power under the Wireless Power Consortium (WPC) Qi v1.3 charging standard.
The Wireless Charging Module version WCM_tx2, Variant B (forward compatible form factor) charges consumer electronics devices wirelessly by supplying power under the Wireless Power Consortium (WPC) Qi v1.3 charging standard.

User Directions| WCM_tx1 and WCM_tx2 have no physically exposed interfaces to
the customer. The module will be installed in the vehicle console underneath a
mat made of rubber or other material with low electrical conductivity. The mat
is the A surface that the customer places their compatible consumer
electronics device onto (interface surface).
Upon detecting the presence of an object on the interface surface, the WCM provides a small amount of power to the device at 128kHz operating frequency. If the device is a compatible consumer electronics device, it will communicate to the WCM via amplitude modulation at 2kHz frequency, and charging will commence with the consumer electronics device controlling the operating point.
Model name| WCM_tx1, WCM_tx2
Wireless Charging
Warning Wireless charging may affect the operation of an implanted pacemaker or other medical devices. If you have one, it is recommended to consult with your doctor before using the wireless charging system.
Warning Remove all objects from the charger before charging your compatible smartphone. Objects, such as coins, keys, rings, paper clips, or cards, between the smartphone and charger may become very hot.
On the rare occasion that the charging system does not detect an object, and the object gets wedged between the smartphone and charger, remove the smartphone and allow the object to cool before removing it from the charger, to prevent burns.
If equipped and enabled, the vehicle has wireless charging in front of the center console storage bin. The system operates at 128 kHz and wirelessly charges one Qi compatible smartphone. The power output of the system is capable of charging at a rate up to 3 amp (15W), as requested by the compatible smartphone. See Radio Frequency Statement (US/CAN) Radio Frequency Statement (MEXICO).
The vehicle must be on or in accessory mode. The wireless charging feature may not correctly indicate charging when a Bluetooth phone call is active.
The operating temperature is −40 °C (−40 °F) to 85°C (185°F) for the charging system and 0 °C (32°F) to 35°C (95°F) for the phone. A charging stopped alert may be displayed on the infotainment screen, if the wireless charger or smartphone are outside of normal operating temperature. Charging will automatically resume when a normal operating temperature is reached.
To charge a smartphone:
- Confirm the smartphone is capable of wireless charging.
- Remove all objects from the charging pad. The system may not charge if there are any objects between the smartphone and charger.
- Place the smartphone face up against the rear of the charger. A thick smartphone case may prevent the charger from working, or reduce the charging performance.
- A green appears on the infotainment display next to the phone icon when the smartphone is detected.
The smartphone may become warm during charging. This is normal. In warmer temperatures, your phone may take longer to charge.
Troubleshooting Wireless Charging
If a smartphone is placed on the charger and a yellow appears, remove the smartphone and any objects from the pocket. Turn the smartphone 180 degrees and wait a few seconds before placing/aligning it on the pocket again.
If a smartphone is placed on the charger and a red appears, the charger and/or the smartphone is overheated. Remove the smartphone and any objects from the charger in order to cool the system.
For vehicles with wireless phone projection, the smartphone may overheat during wireless charging. The smartphone may slow down, stop charging, or shut down to protect the battery. The phone may need to be removed from its case to prevent overheating. The may flash while the phone is cooling down enough for wireless charging to automatically resume. This is normal. Individual phone performance may vary.
Certain vehicle and smartphone accessories may not be compatible with the wireless charging system. See your dealer for additional information.
