Additional Options (RPOs)	Equipped with Infotainment System RPOs IOS, IOT, IOU
Condition	Some customers may comment on software related issues. Continuous improvement software updates are being released with improvements made in several areas. V164 contains over 35 improvements. Refer to V164 Most Notable Improvements section below.
Cause	The cause of the condition may be software anomalies.
Correction	A new radio software update, version V164, was released to service for vehicles equipped with Infotainment system RPO IOS, IOU or IOT. In addition to providing general robustness and stability enhancements, this update includes all enhancements from previous software version releases. NOTE: The IOR radio does not get V164 and uses a totally different software. DO NOT attempt to program an IOR radio with the software referenced in this bulletin. IMPORTANT: Some technicians are reporting that the radio remains on an older software version after the radio displays the software update completed successfully. It is important to ensure that the technician is inspecting the full information found within Build Number and not other rows of information on the same screen. This requires the user to locate the Build Number, and then select the Information icon (circled lower-case i) to see the full software version file name. In these radios, the build number may begin with a letter other than "V" but this is NOT the software version and is not unique to the software release. IMPORTANT: After pressing the information icon, review the full software version file name. In the middle of this long file name you see the V164 (or numerically higher/lower if a different version is installed). IMPORTANT: Improvements will vary by model, build configuration, system, and sales region. Not all vehicles have all features.

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.

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 12 V 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.
Please verify that the radio time and date are set correctly before inserting USB drive into vehicle for programming, otherwise an error will result .
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.
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.

Refer to the Warranty Information section of this bulletin.

Update the Radio module.

IMPORTANT:
To avoid warranty transaction rejections, you MUST record the warranty claim code provided on the Warranty Claim Code (WCC) screen shown above on the job card. Refer to callout 1 above for the location of the WCC on the screen.
Record the SPS Warranty Claim Code on the job card for warranty transaction submission.
