DTC INDEX

DTC Description Action
B1142:27 Ignition Status 1: Signal Rate of Change Above Threshold GO to Pinpoint Test I
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.
B1A89:11 Satellite Antenna: Circuit Short To Ground For a satellite radio concern, GO to Pinpoint Test C
For a SIRIUS Data Services concern, GO to Pinpoint Test D
B1A89:13 Satellite Antenna: Circuit Open For a satellite radio concern, GO to Pinpoint Test C
For a SIRIUS Data Services concern, GO to Pinpoint Test D
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.
U0100:00 Lost Communication With ECM/ PCM "A": No Sub Type Information GO to Pinpoint Test AO
U0140:00 Lost Communication With Body Control Module: No Sub Type Information GO to Pinpoint Test AP
U0142:00 Lost Communication With Body Control Module "B": No Sub Type Information GO to Pinpoint Test AQ
U0155:00 Lost Communication With Instrument Panel Cluster (IPC) Control Module: No Sub Type Information GO to Pinpoint Test AS
U0237:00 Lost Communication With Digital Audio Control Module "C": No Sub Type Information GO to Pinpoint Test AW
U0238:00 Lost Communication With Digital Audio Control Module "D": No Sub Type Information GO to Pinpoint Test AX
U0253:00 Lost Communication With Accessory Protocol Interface Module: No Sub Type Information GO to Pinpoint Test AY
U0256:00 Lost Communication With Front Controls Interface Module "A": No Sub Type Information GO to Pinpoint Test AZ
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 BA
U201A:51 Control Module Main Calibration Data: Not Programmed This DTC sets due to an incorrect or incomplete ACM configuration. Using a diagnostic scan tool, PERFORM the ACM programming procedure using as-built data. For information on as-built data, REFER to: Module Configuration - System Operation and Component Description . See As-Built Data.
U2100:00 Initial Configuration Not Complete: No Sub Type Information This DTC sets due to an incorrect or incomplete ACM configuration. Using a diagnostic scan tool, PERFORM the ACM programming procedure using as-built data. For information on as-built data, REFER to: Module Configuration - System Operation and Component Description . See As-Built Data.
U2101:00 Control Module Configuration Incompatible: No Sub Type Information This DTC sets due to an incorrect or incomplete ACM configuration. Using a diagnostic scan tool, PERFORM the ACM programming procedure using as-built data. For information on as-built data, REFER to: Module Configuration - System Operation and Component Description . See As-Built Data.
U3000:41 Control Module: General Checksum Failure CLEAR the DTC.
WAIT at least 10 seconds.
REPEAT the ACM 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 all Continuous Memory Diagnostic Trouble Codes (CMDTCs).
WAIT at least 10 seconds.
RETRIEVE all Continuous Memory Diagnostic Trouble Codes (CMDTCs).
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 ACM 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 BB
U3003:17 Battery Voltage: Circuit Voltage Above Threshold GO to Pinpoint Test BC
