Additional Options (RPOs)

Equipped with Rear View Camera (UVB), or Surround Camera System (UV2) or (UVS), or Trailer Camera System (UVI)

Condition

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 [camera-error-symbol] 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.

Blue Screen Image Description: The vehicle's infotainment screen displays a blue background with white text stating "Service Rear Vision System" and a camera icon.

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 [warning-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:

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.

The cause of the condition may be software anomalies in the Video Processing Module (VPM) or rear camera.

• Vehicles with UV2/UVI/UVS: Reprogram the Video Processing Module (VPM).
• Vehicles with UVB: Replace the rearview camera.

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:

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:

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

Note:

Troubleshooting Table

Detailed Diagnostic Steps

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.
   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. 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:
   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.
   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.
   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.
   2. If concern(s) persist, refer to published diagnostics in SI.

Caution:

• 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.
