Wireless Accessory Charging Module (WACM)

The WACM inductively charges a single Qi (pronounced \"chee\") compatible mobile device at rates of power of up to 15 Watts. Not all phones or devices charge at 15 watts. A customer should check with their phone manufacturer to determine if it supports Qi wireless charging. Not all phones are compatible with wireless charging. Some device cases or accessories (i.e. pop socket) may prevent or degrade wireless charging performance. It may be necessary for the customer to remove their device from its case.

The WACM is powered at all times (PAAT), receiving power directly from the vehicle's battery. The WACM receives signals from the BCM (CAN signals and a hardwire) to indicate when an interior key search is performed, which the WACM responds by disabling charge briefly, charging resumes after the event ends. The hardwire is a controlled FET that shorts to battery before and during the key search.

The WACM also receives signals from the radio, which allow it to know when to shift frequency to avoid interfering with the AM radio.

The WACM sends signals to Sync to display charging status updates to the users (wireless charger active, foreign/metal object detected, etc).

The WACM features foreign object detection that can detect when metal objects are placed between the device and the charging surface. When this is detected, the center display will display a message until the condition is corrected. For additional tips on how to effectively use the wireless charger, reference the owner's literature.
