THIS SERVICE UPDATE INCLUDES VEHICLES IN DEALER INVENTORY AND CUSTOMER VEHICLES THAT RETURN TO THE DEALERSHIP FOR ANY REASON, AND WILL EXPIRE AT THE END OF THE INVOLVED VEHICLE'S 8 YEAR / 80,000 MILE (130,000 KM) EMISSION CONTROLLER WARRANTY PERIOD.
Purpose
This bulletin provides a service procedure to reprogram the Engine Control Module (ECM) calibration on certain 2006 Cadillac DTS vehicles, equipped with 4.6L V8 (RPO L37 - VIN 9, RPO LD8 - VIN Y) engines; 2006 Chevrolet Cobalt vehicles, equipped with 2.2L 4-cylinder (RPO L61 - VIN F) engines; 2006 Buick Rainier vehicles, equipped with 4.2L I-6 (RPO LL8 - VIN S) engines. The revised calibration includes Secondary Air Injection Reaction (SAIR) OBD system improvements that should be installed as soon as practical. To verify if an updated calibration is required, refer to the following procedure in this bulletin.
This service procedure should be completed as soon as possible on involved vehicles currently in dealer inventory and customer vehicles that return to the dealership for any reason during the New Vehicle 8 year / 80,000 mile (130,000 km) Emission Controller Warranty 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 (US), or attached to the GlobalConnect message (Canada), used to release this bulletin. Customer vehicles that return to the dealership for any reason, and are still covered under the vehicle's emission controller warranty, and are within the VIN breakpoints provided below, should be checked for vehicle eligibility in the appropriate system listed below.
Important
Dealers are to confirm vehicle eligibility prior to beginning repairs by using the Investigate Vehicle History link. Not all vehicles within the above breakpoints may be involved.
Service Procedure
Do not attempt to order the calibration number from GM Customer Care and Aftersales. The calibration numbers required for this service procedure are programmed into control modules via a Tech 2 or Multiple Diagnostic Interface (MDI) and TIS2WEB with the calibration update. When using a Tech 2 or MDI for reprogramming, ensure that it is updated with the latest software version. Use TIS2WEB on or after 07/13/10 to obtain the calibration. If you cannot access the calibration, call the Techline Customer Support Center and it will be provided.
For step-by-step programming instructions, please refer to SI and the Techline Information System (TIS) terminal.
1. Verify that there is a battery charge of 12 to 15 volts. The battery must be able to maintain a charge during programming. Use only an approved Midtronics(R) PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent to maintain proper battery voltage during programming.
2. Reprogram the engine control module (ECM). Refer to SI and Service Programming System (SPS) documentation for programming instructions, if required.
1. Connect the Tech 2 or MDI to the vehicle.
2. Select J-2534 Tech 2 or J-2534 MDI and Reprogram ECU from the Select Diagnostics Tool and Programming Process screen.
3. Select ECM Engine Control Module - Programming from the Supported Controllers screen.
4. Follow the on-screen instructions.
3. Using the Tech 2 or MDI, clear all DTCs, if required.
