| DTC | Description | Action |
|---|---|---|
| B1A56:21 | Antenna: Signal Amplitude < Minimum | GO to PINPOINT TEST A |
| B1A89:01 (without ANC only) | Satellite Antenna: General Electrical Failure |
|
| B1A89:11 (with ANC only) | Satellite Antenna: Circuit Short To Ground |
|
| B1A89:13 | Satellite Antenna: Circuit Open |
|
| B1D19:49 | Compact Disc Unit: Internal Electronic Failure | CLEAR the Diagnostic Trouble Codes (DTCs). REPEAT the self-test. If DTC B1D19:49 is retrieved again, INSTALL a new ACM. REFER to: AUDIO FRONT CONTROL MODULE (ACM) . |
| B1D19:4B | Compact Disc Unit: Over Temperature | The ACM was over-temperature. This may occur during extended use. Audio operation can resume after the ACM cools. CLEAR the Diagnostic Trouble Codes (DTCs). This is normal operation. |
| U0155:00 | Lost Communication With Instrument Panel Cluster (IPC) Control Module: No Sub Type Information | GO to PINPOINT TEST AM |
| U0237:00 | Lost Communication With Digital Audio Control Module "C": No Sub Type Information | GO to PINPOINT TEST AP |
| U0238:00 | Lost Communication With Digital Audio Control Module "D": No Sub Type Information | GO to PINPOINT TEST AQ |
| U0253:00 | Lost Communication With Accessory Protocol Interface Module: No Sub Type Information | GO to PINPOINT TEST AR |
| U0256:00 | Lost Communication With Front Controls Interface Module "A": No Sub Type Information | GO to PINPOINT TEST AS |
| U0257:00 | Lost Communication With Front Controls/Display Interface Module: No Sub Type Information |
NOTE:
Despite the description, this DTC applies to the FDIM, not the FCDIM. GO to PINPOINT TEST AT |
| U201A:51 | Control Module Main Calibration Data: Not Programmed | 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 Programmable Module Installation (PMI) procedure as directed by the scan tool. If there have been no recent service actions, INSTALL a new module to correct the failure to retain configuration data. REFER to: AUDIO FRONT CONTROL MODULE (ACM) . |
| 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 Programmable Module Installation (PMI) procedure as directed by the scan tool. If there have been no recent service actions, INSTALL a new module to correct the failure to retain configuration data. REFER to: AUDIO FRONT CONTROL MODULE (ACM) . |
| 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 Programmable Module Installation (PMI) procedure as directed by the scan tool. If there have been no recent service actions, INSTALL a new module to correct the failure to retain configuration data. REFER to: AUDIO FRONT CONTROL MODULE (ACM) . |
| U3000:41 | Control Module: General Checksum Failure | CLEAR the Diagnostic Trouble Codes (DTCs). REPEAT the self-test. If DTC U3000:41 is retrieved again, INSTALL a new ACM. REFER to: AUDIO FRONT CONTROL MODULE (ACM) . |
| U3000:42 | Control Module: General Memory Failure | CLEAR the Diagnostic Trouble Codes (DTCs). REPEAT the self-test. If DTC U3000:42 is retrieved again, INSTALL a new ACM. REFER to: AUDIO FRONT CONTROL MODULE (ACM) . |
| U3000:96 | Control Module: Component Internal Failure |
|
| U3003:16 | Battery Voltage: Circuit Voltage Below Threshold | GO to PINPOINT TEST AW |
| U3003:17 | Battery Voltage: Circuit Voltage Above Threshold | GO to PINPOINT TEST AX |
