Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Wireless Accessory Charging Module (WACM) - Overview
The BCM provides a protected switch to protected battery input to the WACM when an interior passive key search is in progress to disable the wireless charging feature. This prevents possible interference with the passive key when placed in close proximity to the WACM during a charge session of a secondary device. A redundant CAN signal is also sent by the BCM in addition to the protected switch to protected battery input.
