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.
B1A89:11 Satellite Antenna: Circuit Short To Ground GO to PINPOINT TEST B .
B1A89:13 Satellite Antenna: Circuit Open GO to PINPOINT TEST B .
B1D19:49 Compact Disc Unit: Internal Electronic Failure
  • CLEAR the DTC.
  • WAIT at least 30 seconds.
  • REPEAT the self-test.
  • If DTC B1D19:49 is retrieved again, INSTALL a new ACM. REFER to AUDIO 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.

For more information, REFER to Programmable Module Installation (PMI) in MODULE CONFIGURATION SYSTEM . 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 CHECK vehicle service history for recent service actions related to this module. This DTC sets due to incomplete or incorrect PMI procedures. If there have been recent service actions with this module, REPEAT/PERFORM the PMI procedure as directed by the diagnostic scan tool. For more information, REFER to Programmable Module Installation (PMI) in MODULE CONFIGURATION SYSTEM . 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) .
