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 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.
