Customer Satisfaction - Reprogram Tire Pressure Monitor System (TPMS)

Subject:08040 -- Reprogram Tire Pressure Monitor System (TPMS)

Models:2008 Cadillac STS, STS-V



THIS PROGRAM IS IN EFFECT UNTIL MARCH 31, 2009.

Condition

On certain 2008 model year Cadillac STS and STS-V vehicles, the Tire Pressure Monitor System (TPMS) malfunction indicator may be inoperative. The TPMS is designed to notify the driver of certain malfunctions. When the system detects a malfunction, the low tire warning light should flash for about one minute and then stay on for the remainder of the ignition cycle. A Driver Information Center message will also be displayed on the instrument panel. On these vehicles, these indications of a system malfunction do not work. Without these indications, a driver will not know that the TPMS is not working properly.

Correction

Dealers are to reprogram the Tire Pressure Monitor System.

Vehicles Involved

Involved are certain 2008 model year Cadillac STS and STS-V vehicles built within these VIN breakpoints:

For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided through the applicable system listed below. Dealers will not have a report available if they have no involved vehicles currently assigned.

-- US dealers - GM DealerWorld Recall Information

-- Export dealers - sent directly to 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 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

Calibration Information

Do not attempt to order the calibration number from GMSPO. The calibration numbers required for this service procedure are programmed into control modules via a Techline Tech 2® scan tool for TIS2WEB with the calibration update. Use TIS2WEB on or after 03/03/08 to obtain the calibration. If you cannot access the calibration, call the Techline Customer Support Center at 1-800-828-6860 (English) or 1-800-503-3222 (French) and it will be provided.

Service Programming System (SPS)

For step-by-step programming instructions, please refer to SI and the Techline Information System (TIS) terminal.

Review the information below to ensure proper programming protocol.

Important: 

   • DO NOT program a control module unless you are directed by a service procedure or you are directed by a General Motors Corporation service bulletin. Programming a control module at any other time will not permanently correct a customer's concern.
   • It is essential that the Tech 2® and the TIS terminal are both equipped with the latest software before performing (SPS).
   • Due to the time requirements of programming a controller, it is recommended that an external power source be used to maintain system voltage. Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. To ensure trouble-free programming, GM recommends using one of the following external power sources:
      - A Midtronic PCS charger.
      - A fully charged 12V jumper or booster pack disconnected from the AC voltage supply.
      - Some modules will require additional programming/setup events performed before or after programming.
      - Some vehicles may require the use of a CANDi module for programming.
      - Review the appropriate service information for these procedures.
      - DTCs may set during programming. Clear DTCs after programming is complete.
      - Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system status indicators to NO.

Ensure the following conditions are met before programming a control module:

    • FlexFuel (E85) Vehicles
       - The fuel composition learn function is inactive. Programming with the fuel composition learn active will result in fuel trim DTCs.
       - If necessary, drive the vehicle until the scan tool indicates that the fuel composition learn is inactive.
    • Vehicle System Voltage
       - There is not a charging system concern. All charging system concerns must be repaired before programming a control module.
       - Battery voltage is greater than 12 volts but less than 16 volts. The battery must be fully charged before programming the control module.
       - Turn OFF or disable any system that may put a load on the vehicles battery, such as the following components.
       - Twilight sentinel
       - Interior lights
       - Daytime running lights (DRL) - Applying the parking brake, on most vehicles, disables the DRL system.
       - Heating, ventilation, and air conditioning (HVAC) systems
       - Engine cooling fans, radio, etc.
    • The ignition switch must be in the proper position. SPS 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 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. Attempt to reprogram the control module. If the control module cannot be programmed, replace the control module.
  1. Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Only use approved Midtronics PCS charger, a fully charged 12V jumper, or booster pack disconnected from the AC voltage supply to maintain proper battery voltage during programming.
  2. Reprogram the RCDLR. Refer to SI and Service Programming System (SPS) documentation for programming instructions, if required.
  3. 2.1. Connect the Tech 2® to the vehicle.
    2.2. Select RCDLR from the Supported Controller screen.
    2.3. Follow the on-screen instructions.

Dealer Recall Responsibility

All unsold new vehicles in dealers' possession and subject to this program must be held and inspected/repaired per the service procedure of this program bulletin before customers take possession of these vehicles.

Dealers are to service all vehicles subject to this program at no charge to customers, regardless of mileage, age of vehicle, or ownership, through March 31, 2009.

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.
