Diagnostic Fault Information

Circuit/System Description

For an overview of the component/system, refer to:Mobile Device Wireless Charger Description and Operation

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.

Diagnostic Aids

Verify the mobile device can be charged with the proper wireless charging adapter. To check for phone or other device compatibility, refer to GM Total Connect website.

Verify the charging pad/pocket is free from debris or any obstruction that may impede charging.

The component T22 contains an internal temperature switch that will open if it exceeds 85 °C (185 °F).

The ambient operating temperature is between -20 and 60°C (-4 and 140°F) for the charging system and between 0 and 35°C (32 and 95°F) for the mobile device. If the mobile device temperature exceeds 35 °C (95 °F) the mobile device may stop accepting a charge (this may vary with different mobile devices).

Verify the mobile device is positioned correctly on the charging pad/pocket and there are no foreign objects between the mat and the mobile device. It may be necessary to move the device around slightly or rotate 180 degrees to properly align it on the charging pad/pocket until the device starts to charge. The use of a protective case may require more precise device placement to allow charging or may inhibit charging. Try removing the protective case.

The mobile device may not charge if the charge mat is NOT completely flat or has an air gap which can be verified by a finger push at the target graphic located at the center of the mat. If the charge mat is NOT flat, replace the charge mat/rubber liner.

While operating the vehicle in rough conditions, it is possible for the device to move out of position, repositioning of the device may be necessary.

If the mobile device battery is fully charged, the charge indicator on the P17 Info Display Module may not illuminate.

Removal Procedure

Fig. 8: View Of Cigar Lighter Socket/Accessory Power Outlet Courtesy of GENERAL MOTORS COMPANY

1. Remove the auxiliary power outlet fuse from the fuse block.

2. Remove the receptacle:

1. Look into the receptacle. There are two 3 mm (0.11 in) tab windows 12 mm (0.47 in) from the front of the receptacle. The EL-42059 remover pushes the plastic latches from these tab windows and the receptacle can be pulled straight out.

2. Place one side of the "T" portion of the EL-42059 remover into the tab window. The EL-42059

remover will not fit straight into the receptacle. Angle the slightly for insertion into the receptacle.

3. Insert the other side of the "T" into the opposite tab window.

You must move the EL-42059 remover handle toward horizontal to engage the other tab window.

4. Use the EL-42059 remover to pull the receptacle straight out.

DESCRIPTION AND OPERATION

MOBILE DEVICE WIRELESS CHARGER DESCRIPTION AND OPERATION

Mobile Device Wireless Charging System

Fig. 11: Mobile Device Wireless Charging System Diagram Courtesy of GENERAL MOTORS COMPANY

The Mobile Device Wireless Charging System (WCS) is an system for wirelessly charging mobile devices. It is capable of charging the batteries of compatible mobile devices. A compatible device is one that is compliant with Power Matters Alliance (PMA) or Wireless Power Consortium (WPC) Standard, meaning that it is equipped with a PMA or WPC wireless charge "receiver" that will work with the charge "transmitter" installed in the vehicle. The devices may utilize built-in charging circuitry or an adapter (external plug-in device which contains the charging circuitry). To check for phone or other device compatibility, refer to GM Total Connect.

WARNING: Remove all objects from the charging pad before charging your mobile device. Objects, such as coins, keys, rings, paper clips, or cards, between the phone and charging pad will become very hot. On the rare occasion that the charging system does not detect an object, and the object gets wedged between the phone and charger, remove the phone and allow the object to cool before removing it from the charging pad, to prevent burns.

Charging

To charge a device, place it on the charging surface in the vehicle. There is a charging coil located in the center of the charging surface. The device has a charging coil typically near the center of the device. These coils must

be lined up in order for charging to proceed. When the interruptible retained accessory power (IRAP) relay is closed (this is true typically when vehicle ignition is in Run or Accessory position), the WCS will detect the device, establish communications with the device to confirm it is a compatible device, and then deliver charging power to the device via wireless interface. The WCS will be able to deliver up to 5W of power to compatible devices. It shall only enter a charging state if communication is established and a compatible device is identified.

The WCS shall not enter a charging state if there is no communication established with a compatible device. If a non-compatible device or metallic foreign object is detected, the WCS will not transfer power. The charger monitors its internal temperature and will shut down if the charger temperature exceeds 185F (85C).

Indicator

The body control module will detect the device battery is charging and send a serial data message on the GMLAN bus to the radio display. The radio display will indicate a device is currently charging. When the indicator is toggling on and off this indicates a thermal limit has been reached and the device will not charge. For more information refer to the infotainment owners manual.
