  • 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 CLEAR the DTCs  . REPEAT the self-test. If DTC  U3000:04 is still present, INSTALL a new APIM  . Refer to ACCESSORY PROTOCOL INTERFACE MODULE (APIM) .
U3000:41 Control Module: General Checksum Failure CLEAR the DTCs  . REPEAT the self-test. If DTC  U3000:41 is still present, INSTALL a new APIM  . Refer to ACCESSORY PROTOCOL INTERFACE MODULE (APIM) .
U3000:42 Control Module: General Memory Failure CLEAR the DTCs  . REPEAT the self-test. If DTC  U3000:42 is still present, INSTALL a new APIM  . Refer to ACCESSORY PROTOCOL INTERFACE MODULE (APIM) .
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.
U3003:16 Battery Voltage: Circuit Voltage Below Threshold GO to PINPOINT TEST AF.
