DTC Chart: Wireless Accessory Charging Module (WACM)
Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. For information about these practices, REFER to: Diagnostic Methods .
Network Diagnostic Trouble Codes (DTCs) (U-codes) are often a result of intermittent concerns such as damaged wiring or low battery voltage occurrences. Additionally, vehicle repair procedures, such as module reprogramming, often set network Diagnostic Trouble Codes (DTCs). Replacing a module to resolve a network DTC is unlikely to resolve the concern. To prevent repeat network DTC concerns, inspect all network wiring, especially connectors. Test the vehicle battery. REFER to: Battery .
WACMDTC Chart
| DTC | Description | Action |
|---|---|---|
| B1554:12 | Wireless Accessory Charger Enable/Disable: Circuit Short To Battery | CLEAR the Diagnostic Trouble Codes (DTCs). WAIT at least 30 seconds. REPEAT the self-test. If B1554:12 is retrieved again, GO to Pinpoint Test B If B1554:12 is not retrieved again, then follow PMI procedures. To flash strategy to the latest compatible strategy. |
| B1554:1F | Wireless Accessory Charger Enable/Disable: Circuit Intermittent | CLEAR the Diagnostic Trouble Codes (DTCs). WAIT at least 30 seconds. REPEAT the self-test. If B1554:1F is retrieved again, GO to Pinpoint Test B If B1554:1F is not retrieved again, then follow PMI procedures. To flash strategy to the latest compatible strategy. |
| U0140:00 | Lost Communication With Body Control Module: No Sub Type Information | GO to Pinpoint Test D |
| U0184:00 | Lost Communication With Radio: No Sub Type Information | GO to Pinpoint Test F |
| U0257:00 | Lost Communication With Front Controls / Display Interface Module: No Sub Type Information | GO to Pinpoint Test E |
| U201A:51 | Control Module Main Calibration Data: Not Programmed | CHECK vehicle service history for recent service actions related to this module. This DTC sets due to incomplete or incorrect PMI procedures. If there have been recent service actions with this module, REPEAT/PERFORM the PMI procedure as directed by the scan tool. If there have been no recent service actions, INSTALL a new module to correct the failure to retain configuration data. INSTALL a new WACM. REFER to Wireless Accessory Charging Module (WACM) for the appropriate WACM replacement procedure. |
| U2100:00 | Initial Configuration Not Complete: No Sub Type Information | CHECK vehicle service history for recent service actions related to this module. This DTC sets due to incomplete or incorrect PMI procedures. If there have been recent service actions with this module, REPEAT/PERFORM the PMI procedure as directed by the scan tool. If there have been no recent service actions, INSTALL a new module to correct the failure to retain configuration data. INSTALL a new WACM. REFER to Wireless Accessory Charging Module (WACM) for the appropriate WACM replacement procedure. |
| U2101:00 | Control Module Configuration Incompatible: No Sub Type Information | CHECK vehicle service history for recent service actions related to this module. This DTC sets due to incomplete or incorrect PMI procedures. If there have been recent service actions with this module, REPEAT/PERFORM the PMI procedure as directed by the scan tool. If there have been no recent service actions, INSTALL a new module to correct the failure to retain configuration data. INSTALL a new WACM. REFER to Wireless Accessory Charging Module (WACM) for the appropriate WACM replacement procedure. |
| U3000:41 | Control Module: General Checksum Failure | CLEAR the Diagnostic Trouble Codes (DTCs). WAIT at least 10 seconds. REPEAT the self-test. If U3000:41 is retrieved again, INSTALL a new WACM. REFER to Wireless Accessory Charging Module (WACM) for the appropriate WACM replacement procedure. |
| U3000:42 | Control Module: General Memory Failure | CLEAR the Diagnostic Trouble Codes (DTCs). WAIT at least 10 seconds. REPEAT the self-test. If U3000:42 is retrieved again, INSTALL a new WACM. REFER to Wireless Accessory Charging Module (WACM) for the appropriate WACM replacement procedure. |
| U3000:49 | Control Module: Internal Electronic Failure | CLEAR the Diagnostic Trouble Codes (DTCs). REPEAT the self-test. If U3000:49 is retrieved again, INSTALL a new WACM. REFER to Wireless Accessory Charging Module (WACM) for the appropriate WACM replacement procedure. |
| U3003:16 | Battery Voltage: Circuit Voltage Below Threshold | GO to Pinpoint Test C |
| U3003:17 | Battery Voltage: Circuit Voltage Above Threshold | GO to Pinpoint Test C |
