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. Therefore, tests ran from the bezel diagnostic screen and the DTC  generated from the test can be disregarded.
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) (Vehicles With: AM/FM/CD).
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.

U0257:00 Lost Communication With Front Control/Display Interface Module "A": No Sub Type Information GO to PINPOINT TEST Q
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 diagnostic scan tool. REFER to: MODULE CONFIGURATION - SYSTEM OPERATION AND COMPONENT DESCRIPTION . Programmable Module Installation (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) (Vehicles With: AM/FM/CD).
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 diagnostic scan tool. REFER to: MODULE CONFIGURATION - SYSTEM OPERATION AND COMPONENT DESCRIPTION . Programmable Module Installation (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) (Vehicles With: AM/FM/CD).
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 diagnostic scan tool. REFER to: MODULE CONFIGURATION - SYSTEM OPERATION AND COMPONENT DESCRIPTION . See PROGRAMMABLE MODULE INSTALLATION (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) (Vehicles With: AM/FM/CD).
