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 Service Bulletin # 21-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
• 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.
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

6. If the condition continues, power cycle the K157
Video Processing Module to see if the issue goes away.
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.

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.
• 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. 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: The service technician always needs to
verify that the VIN displayed in the TLC left side drop
down menu and the top center window match the VIN
plate of the vehicle to be programmed prior to using
Service Programming System 2 (SPS2) for
programming or reprogramming a module.
• For the TLC application, service technicians need
to always ensure that the power mode (ignition) is
“ON” before reading the VIN from the vehicle’s
VIN master module and that they do not select a
VIN that is already in the TLC application memory
from a previous vehicle.
• If the VIN that shows up in the TLC top center
window after correctly reading the VIN from the
vehicle does not match the VIN plate of the
vehicle, manually type in the VIN characters from
the vehicle VIN plate into the TLC top center
window and use these for programming or
reprogramming the subject module with the
correct vehicle VIN and software and/or
calibrations.
Page 7
•
The Engine Control Module (ECM) is the master
module (for VIP vehicles) that TLC reads to
determine the VIN of the vehicle. If the VIN read
from the vehicle by TLC does not match the VIN
plate of the vehicle, the ECM also needs to be
reprogrammed with the correct VIN, software and
calibrations that match the vehicle’s VIN plate.
• The Body Control Module (BCM) is the master
module (for GEM vehicles) that TLC reads to
determine the VIN of the vehicle. If the VIN read
from the vehicle by TLC does not match the VIN
plate of the vehicle, the BCM also needs to be
reprogrammed with the correct VIN, software and
calibrations that match the vehicle’s VIN plate.
Caution: Be sure the VIN selected in the drop down
menu (1) is the same as the vehicle connected (2)
before beginning programming.
