DTC CHART - APIM
| DTC | Description | Action |
|---|---|---|
| B1252:04 | USB Port: System Internal Failure | GO to PINPOINT TEST T |
| B1252:11 | USB Port: Circuit Short To Ground | GO to PINPOINT TEST T |
| 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). REPEAT the self-test. If DTC
B12B8:04 is retrieved again, INSTALL a new APIM
. REFER to: SYNC MODULE [APIM]

| B1D79:12 | Microphone Input: Circuit Short To Battery | GO to PINPOINT TEST R |
| B1D79:13 | Microphone Input: Circuit Open | GO to PINPOINT TEST R |
| U0140:00 | Lost Communication With Body Control Module: No Sub Type Information | GO to PINPOINT TEST AB |
| U0155:00 | Lost Communication With Instrument Panel Cluster (IPC) Control Module: No Sub Type Information | GO to PINPOINT TEST AC |
| U0257:00 | Lost Communication With Front Controls/Display Interface Module: No Sub Type Information | GO to PINPOINT TEST AH |
| U0423:00 | Invalid Data Received from Instrument Panel Cluster Control Module: No Sub Type Information | REFER to: INSTRUMENTATION, MESSAGE CENTER AND WARNING CHIMES
. To retrieve and follow Diagnostic Trouble Codes (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 Programmable Module Installation (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: SYNC MODULE [APIM] PROGRAMMING . If there have been no recent service actions, INSTALL a new module to correct the failure to retain configuration data. REFER to: SYNC 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
sets 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 scan tool. REFER to: SYNC MODULE [APIM] PROGRAMMING . If there have been no recent service actions, INSTALL a new module to correct the failure to retain configuration data. REFER to: SYNC MODULE [APIM] . |
| U3000:04 | Control Module: System Internal Failure | GO to PINPOINT TEST O |
| U3000:41 | Control Module: General Checksum Failure | CLEAR the Diagnostic Trouble Codes (DTCs). REPEAT the self-test. If DTC U3000:41 is still present, INSTALL a new APIM . REFER to: SYNC MODULE [APIM] . |
| U3000:42 | Control Module: General Memory Failure | CLEAR the Diagnostic Trouble Codes (DTCs). REPEAT the self-test. If DTC U3000:42 is still present, INSTALL a new APIM . REFER to: SYNC MODULE [APIM] . |
| U3000:88 | Control Module: Bus off |
NOTE:
Network communication/message Diagnostic Trouble Codes (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 Diagnostic Trouble Codes (DTCs). To avoid repeat network concerns, INSPECT for damaged or corroded wiring at the APIM
. Test the vehicle battery, refer to
CHARGING SYSTEM - GENERAL INFORMATION
. 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 AK |
| U3003:17 | Battery Voltage: Circuit Voltage Above Threshold | GO to PINPOINT TEST AL |
