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; If there are no DTCs setting in the VPM, and all DTCs are
setting in the radio, refer to bulletin 20-NA-048.

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
• For vehicles with UV2/UVI/UVS, reprogram the Video Processing Module (VPM).
• For vehicles with UVB – replace the rearview camera.

Service Procedure
Note: Diagnostic steps vary based on the DTCs set,
which module stored the DTCs, the vehicle model and
camera system. Pay attention to the vehicle being
diagnosed, what DTCs and symptom bytes are stored,
and which module stored them to ensure the proper
steps are followed.

Repair Step
UV2, UVI, or UVS
Persistent blue screen with service rear viewing
system or black screen with a red triangle and a
no camera icon, throughout a power cycle.
B101D 3C and/or 39
History in VPM
B395A 08, 72 and/or
3A in Radio or VPM
Step 2.1 –
Reprogram VPM

Persistent blue screen with service rear viewing
system and guidelines (if enabled) or a black
screen with red triangle and no camera icon
throughout a power cycle.
B395A 08,72 and/or 3A
in VPM or Radio–
Check Coax, refer to
PIC6420 for specifics
Step 4.1 – Replace
rearview camera
1. Verify the RPO build of the vehicle being
diagnosed to determine which camera system is in
use (UVB, UV2 or UVI).
2. Record all DTCs stored in the vehicle.
2.1. If the Video Processing Module (VPM) stores
a history B101D symptom byte 3C and/or 39;
or the A11 radio stores a history B395A
symptom byte 08, 72 and/or 3A, do NOT
replace the VPM. Reprogramming the VPM
software may reduce sensitivity of the B101D
setting. Refer to K157 Video Processing
Control Module: Programming and Setup in
SI. This software does not resolve
non-camera related system issues. If a
condition exists that is NOT related to the
camera system, then follow published
diagnostics for the condition reported by the
customer.
2.2. Select the appropriate procedure below
based on vehicle build content.
• Proceed to step 3 for UV2 or UVI systems.
• Proceed to step 4 for UVB systems.
3. For UV2 or UVI equipped systems:
3.1. If the A11 Radio has stored DTC B395A
Symptom Bytes 08, 72, and may also set 3A,
then reprogram the VPM software. Refer to
K157 Video Processing Control Module:
Programming and Setup in SI.
3.2. If concern(s) persist, refer to published
diagnostics in SI.
4. For UVB equipped systems (excluding Holden
Acadia):
Note: If the A11 Radio did not store all three history
DTC B395A Symptom Bytes 08, 72, and 3A, then this
bulletin does not apply. Refer to published bulletins, PIs
and SI documents for further diagnostic steps.
4.1. If the A11 Radio has stored all three history
DTC B395A Symptom Bytes 08, 72, and 3A,
and the blue screen with service rear vision
system with guidelines (if enabled) is
persistent throughout a power cycle, then
replace the rearview camera. Refer to
Rearview Driver Information Camera
Replacement for the appropriate model in SI.
4.2. If concern(s) persist, refer to published
diagnostics in SI.
Caution: Before downloading the update files, be sure
the computer is connected to the internet through a
network cable (hardwired). DO NOT DOWNLOAD or
install the files wirelessly. If there is an interruption
during programming, programming failure or control
module damage may occur.
Please refer to Service Bulletin 2019-010 (AU & NZ
region only) for further details on ALL programming
requirements.
Note: Carefully read and follow the instructions below.
•
•
•
•
Ensure the programming tool is equipped with the
latest software and is securely connected to the
data link connector. If there is an interruption
during programming, programming failure or
control module damage may occur.
Stable battery voltage is critical during
programming. Any fluctuation, spiking, over
voltage or loss of voltage will interrupt
programming. Install a GM Authorized
Programming Support Tool to maintain system
voltage. Refer to www.gmdesolutions.com for
further information. If not available, connect a fully
charged 12V jumper or booster pack disconnected
from the AC voltage supply (N/A for AU & NZ
regions). DO NOT connect a battery charger.
Follow the on-screen prompts regarding ignition
power mode, but ensure that anything that drains
excessive power (exterior lights, HVAC blower
motor, etc) is off.
Clear DTCs after programming is complete.
Clearing powertrain DTCs will set the Inspection/
Maintenance (I/M) system status indicators to NO.

Important: Techline Connect and TIS2WEB screens
shown above.
Important: If the Same Calibration/Software Warning
is noted on the TLC or SPS Summary screen, select
OK and follow on-screen instructions. The system will
generate a warranty claim code (WCC) for
documentation purposes only. Perform service
information (SI) diagnostics to determine the cause of
the condition. Use the applicable labor operation code
when submitting a warranty claim. Do NOT use the
WCC with the warranty claim submission.
Important: When programming a module in GM’s new
Vehicle Intelligence Platform, or VIP, the power mode
(ignition) needs to be off or errors may occur. This
involves the 2020 Chevrolet Corvette, Cadillac CT5 and
CT4, as well as the upcoming full-size Chevrolet, GMC,
Cadillac SUVs and Buick Envision. Serial Data
Message Authentication also needs to have the
ignition off.
1. Reprogram the Video Processing Control Module.
Refer to K157 Video Processing Control Module:
Programming and Setup in SI.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
