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.
Circuit/System Description
For an overview of the component/system, refer to: Mobile Device Wireless Charger Description and Operation
| Circuit | Description |
|---|---|
| Ignition | Supplied from a relay. |
| Signal | The control module input circuit has an internal resistance connected to 12 V. When the switch is closed it will pull the signal voltage low. |
| Ground | Chassis Ground |
| Component | Description |
|---|---|
| T22 Mobile Device Wireless Charger Module | Inductive charging, also known as "wireless charging", uses a magnetic field to transfer energy between two objects. The wireless charger has an induction coil to create an alternating magnetic field. A second induction coil in a portable device takes power from the magnetic field and converts it back into electric current to charge the battery. The two induction coils in proximity work similar as an electrical transformer. |
| K9 Body Control Module | The module controls various vehicle functions like lighting, central door locking, power windows, etc. The control module also reads various switches and sensors and makes their values available via serial data. |
The T22 Mobile Device Wireless Charger Module is controlled by an ignition operated relay and is operational when the ignition is in the Accessory or On position. When a wireless charging device is placed on the charging pad/pocket the charging of the device battery will start. The K9 Body Control Module detects the device battery is charging and sends a serial data message to the P17 Info Display Module which illuminates the charge indicator.
