U0422:00	Invalid Data Received From Body Control Module: No Sub Type Information	RETRIEVE and FOLLOW Diagnostic Trouble Codes (DTCs) present in the BCM. REFER to: Body Control Module (BCM) . * If no Diagnostic Trouble Codes (DTCs) are present in the BCM, DIAGNOSE the observable symptom.
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, using the diagnostic scan tool. REFER to: Module Configuration - System Operation and Component Description . If there have been no recent service actions, INSTALL a new ACM 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	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, using the diagnostic scan tool. REFER to: Module Configuration - System Operation and Component Description . If there have been no recent service actions, INSTALL a new ACM 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	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, using the diagnostic scan tool. REFER to: Module Configuration - System Operation and Component Description . If there have been no recent service actions, INSTALL a new ACM to correct the failure to retain configuration data. REFER to: Audio Front 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 Front Control Module (ACM) .
