| U0140:00 | Lost Communication With Body Control Module: No Sub Type Information | GO to Pinpoint Test Y . |
| U0155:00 | Lost Communication With Instrument Panel Cluster (IPC) Control Module: No Sub Type Information | GO to Pinpoint Test Z . |
| U0257 :00 | Lost Communication With Front Controls/Display Interface Module: No Sub Type Information | GO to Pinpoint Test AE . |
| U0423:00 | Invalid Data Received From Instrument Panel Control Module: No Sub Type Information | REFER to Instrumentation, Message Center, and Warning Chimes to retrieve and follow DTCs present in the IPC. |
| 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 APIM programming as directed by the scan tool. REFER to Accessory Protocol Interface Module (APIM) Programming . If there have been no recent service actions, Refer to APIM Hardware Testing .. |
| U2101:00 | 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 APIM programming as directed by the scan tool. REFER to Accessory Protocol Interface Module (APIM) Programming . If there have been no recent service actions, Refer to APIM Hardware Testing .. |
| U3000:04 | Control Module: System Internal Failure | GO to Pinpoint Test S . |
| U3000:41 | Control Module: General Checksum Failure | CLEAR the DTCs. REPEAT the self-test. If DTC U3000:41 is still present, Refer to APIM Hardware Testing .. |
| U3000:42 | Control Module: General Memory Failure | CLEAR the DTCs. REPEAT the self-test. If DTC U3000:42 is still present, Refer to APIM Hardware Testing .. |
| U3000:88 | Control Module: Bus Off |
NOTE:
Network communication/message DTCs may result from intermittent concerns such as damaged wiring or low battery voltage occurrences. Additionally, vehicle repair procedures such as module reprogramming often set these DTCs. To avoid repeat network concerns, INSPECT for damaged or corroded wiring at the APIM. Test the vehicle battery. Refer to Charging Systems in
Charging System
. Replacing a module to resolve a network DTC is unlikely to resolve the concern. The module could not communicate on the network at a point in time. The fault is currently not present. CLEAR the DTC. REPEAT the network test with the scan tool. |
| U3003:16 | Battery Voltage: Circuit Voltage Below Threshold | GO to Pinpoint Test AF . |
| U3003:17 | Battery Voltage: Circuit Voltage Above Threshold | GO to Pinpoint Test AG . |
