. For a SIRIUS Travel Link concern, GO to Pinpoint Test AC . For a navigation concern (if equipped), GO to Pinpoint Test AB . For a compass concern, GO to Pinpoint Test AD . |
| B1A89:13 | Satellite Antenna: Circuit Open | For a satellite radio concern, GO to Pinpoint Test B
. For a SIRIUS Travel Link concern, GO to Pinpoint Test AC . For a navigation concern (if equipped), GO to Pinpoint Test AB . For a compass concern, GO to Pinpoint Test AD . |

| U0256:00 | Lost Communication With Front Controls Interface Module "A": No Sub Type Information | GO to Pinpoint Test AD . |
| U0257:00 | Lost Communication With Front Controls/Display Interface Module: No Sub Type Information | GO to Pinpoint Test AB . |
| U201A:51 | Control Module Main Calibration Data: Not Programmed | This DTC sets due to incomplete or incorrect PMI procedures. CHECK the vehicle service history for recent service actions related to the ACM. If there have been recent service actions with the ACM, INSTALL as-built data from PTS, following the diagnostic scan tool instructions under Module Programming>As-Built. If there have been no recent service actions, INSTALL a new ACM to correct the failure to retain configuration data. REFER to Audio Control Module (ACM) . |
| 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 ACM. If there have been recent service actions with the ACM, INSTALL as-built data from PTS, following the diagnostic scan tool instructions under Module Programming>As-Built. If there have been no recent service actions, INSTALL a new ACM to correct the failure to retain configuration data. REFER to Audio Control Module (ACM) . |
| 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 ACM. If there have been recent service actions with the ACM, INSTALL as-built data from PTS, following the diagnostic scan tool instructions under Module Programming>As-Built. If there have been no recent service actions, INSTALL a new ACM to correct the failure to retain configuration data. REFER to Audio Control Module (ACM) . |
| U3000:41 | Control Module: General Checksum Failure | CLEAR the DTC. WAIT at least 10 seconds. REPEAT the self-test. If DTC U3000:41 is retrieved again, INSTALL a new ACM. REFER to Audio Control Module (ACM) . |
| 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, INSTALL a new ACM. REFER to Audio Control Module (ACM) . |
| U3000:96 | Control Module: Component Internal Failure | CLEAR the DTC. WAIT at least 10 seconds. REPEAT the self-test. If DTC U3000:96 is retrieved again, INSTALL a new ACM. REFER to Audio Control Module (ACM) . |
