Service Update for Inventory and Customer Vehicles-Noise Passby Calibration-Expires with Base Warranty (Export Only)
| Subject: | 08182 -- Service Update for Inventory and Customer Vehicles -- Noise Passby Calibration - Expires with Base Warranty |
| Models: | Certain 2008 Cadillac CTS, STS-V, SRX Built for Export |
THIS SERVICE UPDATE INCLUDES VEHICLES IN DEALER INVENTORY AND CUSTOMER VEHICLES THAT RETURN TO THE DEALERSHIP FOR ANY REASON. IT WILL EXPIRE AT THE END OF THE INVOLVED VEHICLE'S NEW VEHICLE LIMITED WARRANTY PERIOD.
Purpose
This bulletin provides a service procedure to reprogram the Transmission Control Module (TCM) on certain 2008 model year Cadillac CTS, STS-V and SRX vehicles built in the U.S. for export to Korea & Taiwan. These vehicles may have been built without the noise passby transmission calibration file and will exceed noise passby requirements for Korea and Taiwan.
This service procedure should be completed as soon as possible on involved vehicles currently in dealer inventory and customer vehicles that return to the dealer for any type of service during the New Vehicle Limited Warranty coverage period.
Vehicles Involved
A list of involved vehicles currently in dealer inventory is available on the "Service Update Bulletin Information" link under the "Service" tab in DealerWorld (GM) used to release this bulletin. Customer vehicles that return for service, for any reason, and are still covered under the vehicle's base warranty, and are within the VIN breakpoints provided below, should be checked for vehicle eligibility in the appropriate system listed below.
Year | Division | Model | From | Through |
|---|---|---|---|---|
2008 | Cadillac | CTS | 80114663 | 80167440 |
2008 | Cadillac | STS-V | 80100298 | 80100298 |
2008 | Cadillac | SRX | 80100001 | 80100011 |
Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using the system below. Not all vehicles within the above breakpoints may be involved.
-- GM dealers should use GMVIS.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 Multiple Diagnostic Interface (MDI) or Tech 2® scan tool and TIS2WEB with the calibration update. Use TIS2WEB data version 2.0 for 2008 or later, available on TIS2Web 02/04/2008; and on TIS DVD version 3.0/ 2008 or later. If you cannot access the calibration, call the Techline Customer Support Center and it will be provided.
Service Procedure
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 Multiple Diagnostic Interface (MDI) or Tech 2® and the TIS terminal are 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 vehicle 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. |
- 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.
- Reprogram the Transmission Control Module (TCM). Refer to SI and Service Programming System (SPS) documentation for programming instructions, if required.
- Using the MDI or Tech 2®, clear all DTCs if required.
| 2.1. | Connect the MDI or Tech 2® to the vehicle. |
| Important: Select J2534 MDI or Tech 2® Legacy Pass-Thru and Reprogram TCU from the Select Diagnostic Tool and Programming Process screen. The J2534 MDI will reprogram the module in less time than the Tech 2® scan tool. |
| 2.2. | Select TCM Transmission Control Module from the Supported Controllers screen. |
| 2.3. | Follow the on-screen instructions. |
