APIM DTC CHART - PREMIUM

DTC	Description	Action
B1252:04	USB Port: System Internal Failure	GO to Pinpoint Test S
B1252:11	USB Port: Circuit Short To Ground	GO to Pinpoint Test S
B12B8:04	USB Port #2: System Internal Failure	NOTE: This DTC refers to USB port #2 on the APIM itself, which is not used. INSPECT the APIM USB port #2 for damage and REMOVE any debris. CLEAR the Diagnostic Trouble Codes (DTCs). WAIT at least 10 seconds. REPEAT the self-test. If DTC B12B8:04 is retrieved again, INSTALL a new APIM. REFER to: Accessory Protocol Interface Module (APIM) .
B12B8:11	USB Port #2: Circuit Short To Ground	NOTE: This DTC refers to USB port #2 on the APIM itself, which is not used. INSPECT the APIM USB port #2 for damage and REMOVE any debris. CLEAR the Diagnostic Trouble Codes (DTCs). WAIT at least 10 seconds. REPEAT the self-test. If DTC B12B8:11 is retrieved again, INSTALL a new APIM. REFER to: Accessory Protocol Interface Module (APIM) .
B1D79:01	Microphone Input: General Electrical Failure	GO to Pinpoint Test Q
B1D79:11	Microphone Input: Circuit Short To Ground	GO to Pinpoint Test Q
B1D79:12	Microphone Input: Circuit Short To Battery	GO to Pinpoint Test Q
B1D79:13	Microphone Input: Circuit Open	GO to Pinpoint Test Q
U0140:00	Lost Communication With Body Control Module: No Sub Type Information	GO to Pinpoint Test Z
U0155:00	Lost Communication With IPC Module: No Sub Type Information	GO to Pinpoint Test AA
U0257:00	Lost Communication With Front Control/Display Interface Module: No Sub Type Information	GO to Pinpoint Test AD
U0423:00	Invalid Data Received From Instrument Panel Cluster Control Module: No Sub Type Information	RETRIEVE and FOLLOW Diagnostic Trouble Codes (DTCs) present in the IPC. REFER to: INSTRUMENTATION, MESSAGE CENTER AND WARNING CHIMES .
U2100:00	Initial Configuration Not Complete: No Sub Type Information	CHECK vehicle service history for recent service actions related to this module. This DTC set due to incomplete or incorrect Programmable Module Installation (PMI) procedures. If there have been recent service actions with this module, REPEAT/PERFORM the APIM programming as directed by the diagnostic scan tool. REFER to: Accessory Protocol Interface Module (APIM) Programming . If there have been no recent service actions, INSTALL a new APIM to correct the failure to retain configuration data. REFER to: Accessory Protocol Interface Module (APIM) .
U2101:00	Control Module Configuration Incompatible: No Sub Type Information	CHECK vehicle service history for recent service actions related to this module. This DTC set due to incomplete or incorrect Programmable Module Installation (PMI) procedures. If there have been recent service actions with this module, REPEAT/PERFORM the APIM programming as directed by the diagnostic scan tool. REFER to: Accessory Protocol Interface Module (APIM) Programming . If there have been no recent service actions, INSTALL a new APIM to correct the failure to retain configuration data. REFER to: Accessory Protocol Interface Module (APIM) .
U3000:04	Control Module: System Internal Failure	GO to Pinpoint Test N
U3000:41	Control Module: General Checksum Failure	CLEAR the Diagnostic Trouble Codes (DTCs). WAIT at least 10 seconds. REPEAT the self-test. If DTC U3000:41 is retrieved again INSTALL a new APIM. REFER to: Accessory Protocol Interface Module (APIM) .
U3000:42	Control Module: General Memory Failure	CLEAR the Diagnostic Trouble Codes (DTCs). WAIT at least 10 seconds. REPEAT the self-test. If DTC U3000:42 is retrieved again, INSTALL a new APIM. REFER to: Accessory Protocol Interface Module (APIM) .
U3000:88	Control Module: Bus Off	Network communication/message Diagnostic Trouble Codes (DTCs) can result from intermittent concerns such as damaged wiring or low battery voltage occurrences. Additionally, vehicle repair procedures such as module reprogramming often set these Diagnostic Trouble Codes (DTCs). To avoid repeat network concerns, INSPECT for damaged or corroded wiring at the APIM. TEST the vehicle battery. For 2.0L Duratec-HE, REFER to: CHARGING SYSTEM - 2.0L DURATEC-HE . For 2.0L EcoBoost, REFER to: CHARGING SYSTEM - 2.0L ECOBOOST . Replacing a module to resolve a network DTC is unlikely to resolve the concern. The module was unable to communicate on the network at a point in time. The fault is not currently present. CLEAR the DTC. REPEAT the network test with the diagnostic scan tool.
U3003:16	Battery Voltage: Circuit Voltage Below Threshold	GO to Pinpoint Test AE
U3003:17	Battery Voltage: Circuit Voltage Above Threshold	GO to Pinpoint Test AF
