U2100:00 Initial Configuration Not Complete: No Sub Type Information
  • This DTC sets due to incomplete or incorrect PMI  procedures. CHECK the vehicle service history for recent service actions related to the APIM  .
  • If there have been recent service actions with the APIM  , 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, refer to  APIM HARDWARE TESTING  .
U2101:00 Control Module Configuration Incompatible: No Sub Type Information
  • This DTC sets due to incomplete or incorrect PMI  procedures. CHECK the vehicle service history for recent service actions related to the APIM  .
  • If there have been recent service actions with the APIM  , 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, refer to  APIM HARDWARE TESTING  .

  • CLEAR the DTC.
  • WAIT at least 10 seconds.
  • REPEAT the self-test.
  • If DTC U3000:41 is retrieved again, refer to  APIM HARDWARE TESTING  .
U3000:42 Control Module: General Memory Failure
  • CLEAR the DTC.
  • WAIT at least 10 seconds.
  • REPEAT the self-test.
  • If DTC U3000:42 is retrieved again, refer to  APIM HARDWARE TESTING  .
U3000:88 Control Module: Bus Off
NOTE: Network communication/message 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 DTCs. 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.
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 .
  • CLEAR the DTC.
  • REPEAT the network test with the diagnostic scan tool.
U3003:16 Battery Voltage: Circuit Voltage Below Threshold GO to PINPOINT TEST AH .
U3003:17 Battery Voltage: Circuit Voltage Above Threshold GO to PINPOINT TEST AI .
