Audio Front Control Module (ACM)

DTC Description Action
B150C:01 Automobile Audio Bus (A2B) Node 1: General Electrical Failure GO to Pinpoint Test F
B150C:11 Automobile Audio Bus (A2B) Node 1: Circuit Short To Ground GO to Pinpoint Test F
B150C:12 Automobile Audio Bus (A2B) Node 1: Circuit Short To Battery GO to Pinpoint Test F
B150C:13 Automobile Audio Bus (A2B) Node 1: Circuit Open GO to Pinpoint Test F
B150C:55 Automobile Audio Bus (A2B) Node 1: Not Configured This DTC sets when the ACM is not able to properly configure the audio DSP module via the AAB cable. 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.
B150C:87 Automobile Audio Bus (A2B) Node 1: Missing Message GO to Pinpoint Test F
B150C:8F Automobile Audio Bus (A2B) Node 1: Erratic This DTC sets when the ACM is not able to properly configure the audio DSP module via the AAB cable. 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.
B150C:95 Automobile Audio Bus (A2B) Node 1: Incorrect Assembly GO to Pinpoint Test F
B1511:01 Automobile Audio Bus (A2B) Master Node: General Electrical Failure GO to Pinpoint Test F
B1511:11 Automobile Audio Bus (A2B) Master Node: Circuit Short To Ground GO to Pinpoint Test F
B1511:12 Automobile Audio Bus (A2B) Master Node: Circuit Short To Battery GO to Pinpoint Test F
B1511:13 Automobile Audio Bus (A2B) Master Node: Circuit Open GO to Pinpoint Test F
B1511:95 Automobile Audio Bus (A2B) Master Node: Incorrect Assembly 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 vehicle assembly 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, GO to Pinpoint Test T
For a compass concern, GO to Pinpoint Test V
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, GO to Pinpoint Test T
For a compass concern, GO to Pinpoint Test V
B1D19:49 Compact Disc Unit: Internal Electronic Failure GO to Pinpoint Test Q
B1D19:4B Compact Disc Unit: Over Temperature GO to Pinpoint Test Q
B1D55:11 Antenna #2: Circuit Short To Ground GO to Pinpoint Test A
B1D55:15 Antenna #2: Circuit Short To Battery or Open GO to Pinpoint Test A
U0100:00 Lost Communication With ECM/PCM "A": No Sub Type Information GO to Pinpoint Test Y
U0140:00 Lost Communication With Body Control Module: No Sub Type Information GO to Pinpoint Test AA
U0155:00 Lost Communication With Instrument Panel Cluster (IPC) Control Module: No Sub Type Information GO to Pinpoint Test AC
U0237:00 Lost Communication With Digital Audio Control Module "C": No Sub Type Information GO to Pinpoint Test AG
U0238:00 Lost Communication With Digital Audio Control Module "D": No Sub Type Information GO to Pinpoint Test AH
U0253:00 Lost Communication With Accessory Protocol Interface Module: No Sub Type Information GO to Pinpoint Test AK
U0256:00 Lost Communication With Front Controls Interface Module "A": No Sub Type Information GO to Pinpoint Test AL
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 (CM DTCs).
WAIT at least 10 seconds.
RETRIEVE all Continuous Memory Diagnostic Trouble Codes (CM DTCs).
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 AM
