DTC INDEX
| DTC | Description | Action |
|---|---|---|
| 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 |
|
| 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. |
| U0155:00 | Lost Communication With IPC Control Module: No Sub Type Information | GO to PINPOINT TEST AH |
| U0238:00 | Lost Communication With Digital Audio Control Module "D": No Sub Type Information | GO to PINPOINT TEST AK |
| U0253:00 | Lost Communication With Accessory Protocol Interface Module: No Sub Type Information | GO to PINPOINT TEST AL |
| U0256:00 | Lost Communication With Front Controls Interface Module "A": No Sub Type Information | GO to PINPOINT TEST AM |
| 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) . |
