| B1A56:21 | Antenna: Signal Amplitude < Minimum |
NOTE:
If DTC B1A56:21 sets after running the self diagnostic test, 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, the DTC generated from the test can be disregarded. DISREGARD this DTC |
| B1D19:49 | Compact Disc Unit: Internal Electronic Failure | CLEAR the DTCs. 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 DTCs. This is normal operation. |
| U0155:00 | Lost Communication With Instrument Panel Cluster (IPC) Control Module: No Sub Type Information | GO to PINPOINT TEST R . |
| U0257:00 | Lost Communication With Front Controls/Display Interface Module: No Sub Type Information | GO to PINPOINT TEST T . |
| 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 PMI procedures. If there have been recent service actions with this module, REPEAT/PERFORM the PMI procedure as directed by the scan tool. If there have been no recent service actions, INSTALL a new module to correct the failure to retain configuration data. REFER to AUDIO 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 PMI procedures. If there have been recent service actions with this module, REPEAT/PERFORM the PMI procedure as directed by the scan tool. If there have been no recent service actions, INSTALL a new module 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 scan tool. If there have been no recent service actions, INSTALL a new module to correct the failure to retain configuration data. REFER to AUDIO CONTROL MODULE (ACM) . |
| U3000:41 | Control Module: General Checksum Failure | CLEAR the DTCs. REPEAT the self-test. If DTC U3000:41 is retrieved again, INSTALL a new ACM. REFER to AUDIO CONTROL MODULE (ACM) . |
| U3000:42 | Control Module: General Memory Failure | CLEAR the DTCs. REPEAT the self-test. If DTC U3000:42 is retrieved again, INSTALL a new ACM. REFER to AUDIO CONTROL MODULE (ACM) . |
| U3003:16 | Battery Voltage: Circuit Voltage Below Threshold | GO to PINPOINT TEST U . |
| U3003:17 | Battery Voltage: Circuit Voltage Above Threshold | GO to PINPOINT TEST V . |
