Audio Front Control Module (ACM)
DTC INDEX
| DTC | Description | Action |
|---|---|---|
| B1142:27 | Ignition Status 1: Signal Rate of Change Above Threshold | GO to Pinpoint Test F |
| 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 B For a SIRIUS Travel Link concern, GO to Pinpoint Test C For a navigation concern (if equipped), GO to Pinpoint Test AB For a compass concern, GO to Pinpoint Test AD |
| 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 For a navigation concern (if equipped), GO to Pinpoint Test AB For a compass concern, GO to Pinpoint Test AD |
| B1D19:49 | Compact Disc Unit: Internal Electronic Failure | GO to Pinpoint Test Y |
| B1D19:4B | Compact Disc Unit: Over Temperature | GO to Pinpoint Test Y |
| U0100:00 | Lost Communication With ECM/PCM "A": No Sub Type Information | GO to Pinpoint Test AE |
| U0140:00 | Lost Communication With Body Control Module: No Sub Type Information | GO to Pinpoint Test AG |
| U0155:00 | Lost Communication With Instrument Panel Cluster (IPC) Control Module: No Sub Type Information | GO to Pinpoint Test AI |
| U0237:00 | Lost Communication With Digital Audio Control Module "C": No Sub Type Information | GO to Pinpoint Test AL |
| U0238:00 | Lost Communication With Digital Audio Control Module "D": No Sub Type Information | GO to Pinpoint Test AM |
| U0253:00 | Lost Communication With Accessory Protocol Interface Module: No Sub Type Information | GO to Pinpoint Test AQ |
| U0256:00 | Lost Communication With Front Controls Interface Module "A": No Sub Type Information | GO to Pinpoint Test AR |
| 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, CARRY OUT 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, CARRY OUT the ACM PMI procedure using 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, CARRY OUT the ACM PMI procedure using as-built data. |
| U3000:41 | Control Module: General Checksum Failure | CLEAR the DTC. WAIT at least 10 seconds and then REPEAT the ACM self-test. If this DTC 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 and then REPEAT the ACM self-test. If this DTC 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 and then REPEAT the ACM self-test. If this DTC 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 AS |
| U3003:17 | Battery Voltage: Circuit Voltage Above Threshold | GO to Pinpoint Test AT |
