DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1554:11 | Wireless Accessory Charger Enable\Disable: Circuit short to ground | This DTC sets when the module senses lower than expected voltage on the WACM hardwired status circuit, indicating a short to ground. The primary method of configuring WACM off during an interior key search may not work; the CAN signal backup is the only mechanism to prevent WACM from interfering with an interior key search. |
| B1554:13 | Wireless Accessory Charger Enable\Disable: Circuit open | This DTC sets when the module senses no voltage on the WACM hardwired status circuit, indicating an open circuit. The primary method of configuring WACM off during an interior key search may not work; the CAN signal backup is the only mechanism to prevent WACM from interfering with an interior key search. |

- WACM
Visual Inspection and Diagnostic Pre-checks
- Recheck wireless charging process with a known good smart phone that contains the built-in wireless charging technology. Or test wireless charging process with a cell phone with a wireless-capable back cover or adapter.
- With a known compatible cell phone resting on the WACM pad, monitor the FCIM (if equipped) or IPC message center (if equiped) for the WACM charging status message "Wireless Charger Active" message displays after a cell phone has been laid on the charging pad and started a wireless charging session (may only appear on first charging session of a given ignition cycle). A recheck of this message can be performed by turning the ignition off, then back on, then placing the compatible phone back on the charging pad.
- The "Charge Terminated" message will appear immediately after a foreign object /phone misaligned is detected on the charging pad.
- Inspect for loose or corroded WACM connections.
