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 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 (if equipped with navigation), GO to Pinpoint Test C
For a navigation concern (if equipped), GO to Pinpoint Test AC
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 (if equipped with navigation), GO to Pinpoint Test C
For a navigation concern (if equipped), GO to Pinpoint Test AC
For a compass concern, GO to Pinpoint Test AD
B1D19:49 Compact Disc Unit: Internal Electronic Failure GO to Pinpoint Test Z
B1D19:4B Compact Disc Unit: Over Temperature GO to Pinpoint Test Z
U0155:00 Lost Communication With IPC Control Module: No Sub Type Information GO to Pinpoint Test AI
U0238:00 Lost Communication With Digital Audio Control Module "D": No Sub Type Information GO to Pinpoint Test AL
U0253:00 Lost Communication With Accessory Protocol Interface Module: No Sub Type Information GO to Pinpoint Test AM
U0256:00 Lost Communication With Front Controls Interface Module "A": No Sub Type Information GO to Pinpoint Test AN
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 (EXCEPT ELECTRIC VEHICLE) 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 (EXCEPT ELECTRIC VEHICLE) 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 (EXCEPT ELECTRIC VEHICLE) 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 AO
U3003:17 Battery Voltage: Circuit Voltage Above Threshold GO to Pinpoint Test AP
