DTC INDEX

DTC Description Action
B1A06:02 Speaker #6: General Signal Failure GO to Pinpoint Test J
B1A06:11 Speaker #6: Circuit Short To Ground GO to Pinpoint Test J
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 For a satellite radio concern, GO to Pinpoint Test B
For a SIRIUS Travel Link concern, GO to Pinpoint Test C
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 C
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.
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) .
U0155:00 Lost Communication With Instrument Panel Cluster (IPC) Control Module: No Sub Type Information GO to Pinpoint Test AM
U0237:00 Lost Communication With Digital Audio Control Module "C": No Sub Type Information GO to Pinpoint Test AR
U0253:00 Lost Communication With Accessory Protocol Interface Module: No Sub Type Information GO to Pinpoint Test AS
U0256:00 Lost Communication With Front Controls Interface Module "A": No Sub Type Information GO to Pinpoint Test AT
U0257:00 Lost Communication With Front Controls / Display Interface Module: No Sub Type Information
NOTE: Despite the description, this DTC applies to the FDIM, not the FCDIM
GO to Pinpoint Test AU
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 . 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) .
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 . 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) .
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) .
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) .
U3003:16 Battery Voltage: Circuit Voltage Below Threshold GO to Pinpoint Test AW
U3003:17 Battery Voltage: Circuit Voltage Above Threshold GO to Pinpoint Test AX
