Models:
2005-2006 Cadillac CTS, STS
Supercede:
THE LABOR TIME IN THIS BULLETIN IS BEING REVISED. PLEASE DISCARD ALL COPIES OF BULLETIN 05111, ISSUED MARCH 2006.
Condition
General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2005-2006 Cadillac CTS and STS vehicles. Some of these vehicles have a condition where fuel stops flowing to the engine even though the fuel gauge indicates approximately 1/8 tank of gas in the vehicle. The Fuel Level Low indicator does not illuminate and the warning chime does not activate. If this were to occur, the vehicle would stop running due to inadequate fuel supply.
Correction
Dealers are to reprogram the powertrain control module (PCM).
Vehicles Involved
Involved are certain 20005-2006 Cadillac CTS and STS vehicles built within the VIN breakpoints shown.
Important:
Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) prior to beginning program repairs. [Not all vehicles within the above breakpoints may be involved.]
For US and Canada: For dealers with involved vehicles, a Campaign Initiation Detail Report (CIDR) containing the complete vehicle identification number, customer name and address data has been prepared and will be loaded to the GM DealerWorld (US) Recall Information, GMinfoNet (Canada) Recall Reports. Dealers will not have a report available if they have no involved vehicles currently assigned.
For Export: For dealers with involved vehicles, a Campaign Initiation Detail Report containing the complete vehicle identification number, customer name and address data has been prepared, and is being furnished to involved dealers. Dealers will not receive a report with the recall bulletin if they have no involved vehicles currently assigned.
The Campaign Initiation Detail Report 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 recall 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 recall.
Parts Information
No parts are required for this recall.
Service Procedure
Reprogramming the Powertrain Control Module (PCM)
Note:
Before reprogramming, please check the battery condition to prevent a reprogram error of the Powertrain Control Module due to battery discharge. Battery voltage must be between 12 and 16 volts during reprogramming. If the vehicle battery is not fully charged, use jumper cables from an additional battery. Be sure to turn off or disable any system that may put a load on the battery such as automatic headlamps, daytime running lights, interior lights, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if battery voltage guidelines are not observed.
The ignition switch must be in the proper position. The Tech 2 prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so.
Make certain all tool connections are secure, including the following components and circuits:
^ The control module serial data link tester
^ The RS-232 communication cable port
^ The connection at the data link connector (DLC)
^ The voltage supply circuits
DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur.
DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date.
Program the powertrain control module (PCM) to the latest calibration part number. Use of the Pass Thru programming method is recommended, and use of both the Tech2 with CANDi module and the TIS terminal is required. The procedure below is for Pass Thru programming.
Important:
Use data version 3.0 or later, broadcast to dealers on March 5, 2006; and on TIS CD-ROM version 3.0/2006, mailed to dealers beginning March 16, 2006.
To complete this service procedure, the TECH 2 must also be updated to release 26.002 or greater. If you cannot access the calibration, call the Techline Customer Support Center and it will be provided.
1. Verify the battery charge of 12 to 16 volts. The battery must be able to maintain the charge during programming. Use an additional jump battery if necessary.
2. Connect the Tech 2 to the vehicle and the TIS terminal.
3. Turn the ignition to ON with the engine OFF.
4. Turn off or disable any systems that may place a load on the battery during programming, such as automatic headlamps, radio, interior lights, etc.
5. After all warning chimes inside the vehicle have stopped, turn on the Tech 2.
6. On the TIS terminal go into SPS Programming.
7. Select Pass Thru programming.
8. Follow the instruction on the TIS terminal. When you get to the Supported Controllers screen.
8.1. Scroll down in the top box and select PCM/VCM, Powertrain Control Module/Vehicle Control Module.
8.2. In the lower box, select Normal.
8.3. Select Next.
9. When the calibrations screen comes up, pick the calibration described as, "CalibraUonn addresses customer concern of fuel gage accuracy" (or any later supersession) and select Next.
10. Follow the on-screen prompts until programming is completed.
11. When the programming is complete.
11.1. Turn off the Tech2.
11.2. Turn off the ignition switch.
12. Wait 30 seconds.
13. Turn the ignition switch to ON with engine OFF.
14. Turn on the Tech 2.
15. Go into Diagnostics and check for DTC codes.
16. Clear all codes.
Courtesy Transportation
The General Motors Courtesy Transportation Program is intended to minimize customer inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited Warranty. The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period and involved in a product recall is very important in maintaining customer satisfaction. Dealers are to ensure that these customers understand that shuttle service or some other form of courtesy transportation is available and will be provided at no charge. Dealers should refer to the General Motors Service Policies and Procedures Manual for courtesy transportation guidelines.

Customer Notification - For US and Canada
General Motors will notify customers of this recall on their vehicle (see copy of customer letter shown in this bulletin). Customers were sent an advisory letter on December 23, 2005 to advise them to keep their fuel level above 1/4 tank.
Customer Notification - For Export
Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the sample letter.
Dealer Responsibility - For US and Export (US States, Territories, and Possessions)
The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable time.
Dealer Program Responsibility
All unsold new vehicles in dealers possession and subject to this recall must be held and inspected/repaired per the service procedure of this recall bulletin before customers take possession of these vehicles.
Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward. Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer 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 shown in this bulletin for your use in contacting customers. Recall 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 recall enters your vehicle inventory, or is in your dealership for service in the future, you must take the steps necessary to be sure the recall correction has been made before selling or releasing the vehicle.
