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. 5733397 Blue Screen Bulletin No.: 19-NA-076 May, 2021 Page 3 5733400 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. Page 4 May, 2021 Bulletin No.: 19-NA-076 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. RPO Condition DTCs 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 UVB 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 NOTconnect 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. Bulletin No.: 19-NA-076 May, 2021 Page 5 5644477 5431207 Page 6 May, 2021 Bulletin No.: 19-NA-076 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. 5644478 Bulletin No.: 19-NA-076 May, 2021 Page 7 5431209 Important: To avoid warranty transaction rejections, you MUST record the warranty claim code provided on the SPS Warranty Claim Code (WCC) screen shown above on the job card. Refer to callout 1 above for the location of the WCC on the SPS screen. 2. Record the SPS Warranty Claim Code on the job card for warranty transaction submission. Parts Information Use the VIN and the Electronic Parts Catalog (EPC) to determine the proper part number for your specific application.
