B1A56:21	Antenna: Signal Amplitude < Minimum	If DTC B1A56:21 sets after running the bezel diagnostic tests, DISREGARD this DTC . This test is used for end of line or repair bay testing at the Ford plant. Each plant has its own assigned frequency and signal strength requirements. The running and passing of this test depends on local radio stations. If no local station is broadcasting on the required frequency, the test will fail.
B1D19:49	Compact Disc Unit: Internal Electronic Failure	CLEAR the DTC . WAIT at least 10 seconds. 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 DTC . This is normal operation.
U0155:00	Lost Communication With IPC Control Module: No Sub Type Information	GO to PINPOINT TEST Z
U0253:00	Lost Communication With Accessory Protocol Interface Module: No Sub Type Information	GO to PINPOINT TEST AB
U0257:00	Lost Communication With Front Control/Display Interface Module: No Sub Type Information	GO to PINPOINT TEST AC
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 , REPEAT/PERFORM the PMI procedure as directed by the diagnostic scan tool. REFER to: MODULE CONFIGURATION - SYSTEM OPERATION AND COMPONENT DESCRIPTION . See PMI. 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 , REPEAT/PERFORM the PMI procedure as directed by the diagnostic scan tool. REFER to: MODULE CONFIGURATION - SYSTEM OPERATION AND COMPONENT DESCRIPTION . See PMI. 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 , REPEAT/PERFORM the PMI procedure as directed by the diagnostic scan tool. REFER to: MODULE CONFIGURATION - SYSTEM OPERATION AND COMPONENT DESCRIPTION . See PMI. 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) .
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 Front 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 Front Control Module (ACM) .
