GM Korea Company, China, Egypt, Other Africa, Australia/New Zealand
Additional Options (RPOs)
Equipped with Rear View Camera (UVB), or Surround Camera System (UV2) or (UVS),
or Trailer Camera System (UVI)
Some customers may comment on a blue or black screen with Service Rear Vision
System message when shifting into Reverse.
Tip: (Truck only) Refer to Service Bulletin # 18-NA-383 for additional steps and how to
identify if this is a water intrusion issue.
Surround / Trailer Camera (UV2, UVS, or UVI) Systems
The blue screen (with Service Rear Vision message), or black screen (with red triangle
and no camera icon) condition can occur multiple times within the same power cycle and
may return to normal functionality on the next power cycle. Or if this condition exists, it will
occur every time the rear view is displayed to the customer within the same power cycle
and may return to normal functionality on the next power cycle after the A11 radio enters
and exits sleep cycle. A Diagnostic Trouble Code (DTC) B101D Symptom Byte 3C and/or
39 may be stored as a history DTC in the Video Processing Module (VPM) without any
camera-related concern.

Bulletin No.: 19-NA-076

Black Screen
Some customers with select vehicles may notice that after having vehicle in idle for an
extended period of time (length of time for black screen to occur depends on ambient
temperature), a black screen with a red triangle and no camera icon will appear when the
vehicle is put in Reverse and the camera icon will be crossed out on the radio center
screen.
Important: This condition can sometimes appear within approximately 25 minutes of
starting a vehicle and is all dependent on the vehicle being in idle.
Please refer to Rear Vision Camera System Malfunction (UV2) in SI for any blue screen
in Reverse with the message “Service Rear Vision System” situations with vehicles
equipped with UV2, XVR. This particular scenario may become present when there is a
B101D or B101E DTC that returns after replacing a VPM. It is advised with vehicles
equipped with UV2 and XVR to remove the video recorder SD card from hub to see if this
fixes this blue screen condition before further root causing.
Rear View Camera (UVB) systems
If the blue or black screen condition exists, it will occur every time the rear view is
displayed to the customer within the same power cycle and may return to normal
functionality on the next power cycle after the A11 radio enters and exits a sleep cycle. A
DTC of B395A Symptom Byte 08, 72 and 3A will be stored as history together in the A11
Radio.
Cause
The cause of the condition may be software anomalies in the Video Processing Module
(VPM) or rear camera.
Correction
• Vehicles with UV2/UVI/UVS — reprogram the Video Processing Module (VPM).
• Vehicles with UVB — replace the rearview camera.

Service Procedure
Important: Service agents must comply with all
International, Federal, State, Provincial, and/or
Local laws applicable to the activities it performs
under this bulletin, including but not limited to
handling, deploying, preparing, classifying,
packaging, marking, labeling, and shipping
dangerous goods. In the event of a conflict between
the procedures set forth in this bulletin and the
laws that apply to your dealership, you must follow
those applicable laws.
The intent of this bulletin is to show that in most cases
DTC B101E or B101D should NOT result in the
replacement of the Video Processing Module (VPM) or
the Radio, but instead inspect for coax and connector
issues as well as the SD Card to ensure it is not
corrupt.
Bulletin No.: 19-NA-076
These counters are listed in priority order from most
usefulness to least. The ones outlined in red are
considered the most critical and usually most helpful in
root causing surround viewing issues.
Note: The VPM fail counters are not available on VIP
architecture vehicles currently.
1. Connect the scan tool to the vehicle’s data link
connector and open GDS2 in the Techline Connect
application and write down all DTCs stored in the
vehicle.
2. Navigate to the VPM Module to observe the Fail
Counters:
Module Diagnostics / K157 Video Processing
Module / Video Processing Module Internal Status.
6100776
3. The three most critical parameters to look at are:
• Camera Communication Fail Counter
• Video Processing Module Reset Counter
• Camera Open Circuit Counter
4. Write down the counters found in the VPM using
the scan tool.
5. Cross-reference the DTCs and counters with the
troubleshooting table below to determine most
probable cause.
