Cadillac CT6 2018 2018 UKL Hands-Free Lane Following (Super Cruise)

Involved vehicles are marked “open” on the Investigate Vehicle History screen in GM Global Warranty Management system. This site should always be checked to confirm vehicle involvement prior to beginning any required inspections and/or repairs.

Condition A software update package is available for the 2018 Cadillac CT6 with Super Cruise.

The enhanced Super Cruise software will improve lane centering and add descriptive instrument cluster messaging that will allow drivers to better understand why Super Cruise is unavailable or why Super Cruise needs to disengage and return control to the driver. We’ve heard feedback from customers that they would like additional information on the operation of the Super Cruise feature and we’ve added new descriptive messaging to address this request.

As a result of the software updates being provided, system performance will be enhanced in the following ways:

  • Easier to Engage Super Cruise. Customers will notice in some situations the Super Cruise symbol now appears more easily when centering their vehicle in the lane allowing them to engage Super Cruise. This includes the ability to more easily reengage Super Cruise after making a lane change.
  • Improved Adaptive Cruise Control. The adaptive cruise control portion of Super Cruise has been enhanced to provide smoother acceleration and braking behavior. Certain 2018 model year Cadillac CT6 vehicles, equipped with Super Cruise, may have a condition in which the vehicle, under certain road conditions may shift left or right while traveling in its lane during Super Cruise operation. Additionally, if the Super Cruise system is not able to be engaged, the cluster messaging only shows “unavailable” without further details on why the system is not available.
Correction Dealers are to update the Super Cruise software, and provide the customer with an owner manual insert that outlines the new available cluster messaging.

Service Procedure

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. When required install the EL-49642 SPS Programming Support Tool to maintain system voltage. 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.
  • Turn OFF or disable systems that may put a load on the vehicles battery such as; interior lights, exterior lights (including daytime running lights), HVAC, radio, etc.
  • Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system status indicators to NO.

Same Calibration/Software Warning

Note: If the Same Calibration/Software Warning is noted on the SPS controller screen, select “OK” and continue programming.

Note: Modules should be programmed in the order listed. Cycle the ignition off and back on between each programming event.

Dealer Responsibility

All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in dealers’ possession and subject to this program must be held and inspected/repaired per the service procedure of this bulletin before customers take possession of these vehicles. Involved vehicles must be held and not delivered to customers, dealer-traded, released to auction, used for demonstration, or any other purpose.

All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned Inventory System (CPOIS) will be de-certified and must be held and remedied per the service procedure in this bulletin. Upon submitting an accepted/paid warranty transaction in the Global Warranty Management (GWM) system, the vehicle can be re-certified for sale within the CPOIS system, or once again be used in the CTP program.

Dealers are to service all vehicles subject to this program at no charge to customers, regardless of mileage, age of vehicle, or ownership, through May 31, 2020. Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the involved vehicle listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. A copy of the customer letter is provided in this bulletin for your use in contacting customers. Program follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this program enters your vehicle inventory, or is in your facility for service through May 31, 2020, you must take the steps necessary to be sure the program correction has been made before selling or releasing the vehicle.

 

Dealer Reports

For dealers with involved vehicles, a listing with involved vehicles has been prepared and will be provided to U.S. and Canadian dealers through the GM GlobalConnect Recall Reports, or sent directly to export dealers. The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this program is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this program.

 

Courtesy Transportation — For USA & Canada

Courtesy transportation is available for customers whose vehicles are involved in a product program and still within the warranty coverage period. See General Motors Service Policies and Procedures Manual, Sections 1.4 and 6.1.10, for courtesy transportation program details.

GM Diagnostic/Programming (TIS2Web)

Approved J2534 Device with TIS2WEB can reprogram 1996 and later All GM Modules.

To obtain the latest electronic controller calibration information for your vehicle, go to https://tis2web.service.gm.com/tis2web and enter the vehicle’s 17 character Vehicle Identification Number (VIN) and select ‘Get CAL ID’.

You can then compare the latest part number with the actual number installed on the vehicle to determine if a reprogram is needed.

The Service Programming System (SPS) application is part of the TIS2Web system. To program an ECU, the SPS application must communicate with the vehicle control modules using the proper J2534 programming interface tool.

The following are the supported interface tools:

OEM GM Tech 2 Dealer Package
Bosch GM MDI 2 (2nd Gen) MDI2 interface
Drew Tech CarDaq-Plus 2 SAE J2534-1/2 Reflash Reprogramming Tool OEM Diagnostics
Drew Technologies (DRWCDPLUSKIT) CarDAQ-Plus J2534 Flash Reprogramming Kit
Drew Tech CarDaq-M 2 SAE J2534-1/2 Reflash Reprogramming Tool OEM Diagnostics
Drew Tech Mongoose Pro Oem Diagnostics And Programing Cable General Motors GM 2  
VSI J2534 ECU Reprogrammer & Diagnostic Adapter
Autel MaxiFlash Elite J2534 ECU Programming Tool
Autel (AULMF2534) MaxiFlash Pro
Dearborn d-Bridge Adapter J2534 OBDII Engineering Tool

The Tech 2 supports model years 1996 and beyond. With the addition of the CAN Diagnostic Interface (CANdi) module, Tech 2 is fully backward compatible with current Tech 2 functionality and operates transparently when diagnosing non-CAN-equipped vehicles.

Servicing the next generation Global A vehicles will require the diagnostic software, GDS2, Global Diagnostic System 2 running on a local PC device while the MDI is connected to the vehicle.

The GM MDI is the Global Diagnostic tool for future vehicles starting with Global A vehicles. The GM MDI was introduced in the fall of 2007 for Pass-Thru programming and offers faster programming speed. It can be used to perform Pass-Thru programming on all vehicles built since 1996 and into the future. Click here to view a list of GDS supported vehicles.
