Service Update for Inventory and Customer Vehicles-OBD System Improvements for DTC P013B- Reprogram Engine Control Module - Expires w/8 yr/80,000 mi (130,000 km) Emission Controller Warranty

THIS SERVICE UPDATE INCLUDES VEHICLES IN DEALER/RETAILER INVENTORY AND CUSTOMER VEHICLES THAT RETURN TO THE DEALERSHIP/RETAIL FACILITY 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.

This bulletin provides a service procedure to reprogram the Engine Control Module (ECM) calibration on certain 2008 Chevrolet Malibu and Saturn Aura vehicles, equipped with a 2.4L 4-cylinder (RPO LE5 - VIN B) engine. The revised calibration includes post-oxygen sensor diagnostic 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/retailer inventory and customer vehicles that return to the dealer/retailer for any type of service during the New Vehicle Limited Warranty coverage period.

A list of involved vehicles currently in dealer/retailer inventory is available on the "Service Update Bulletin Information" link under the "Service" tab in DealerWorld (GM and Saturn US), or attached to the Dealer Communication (Canada), used to release this bulletin. Customer vehicles that return for service, for any reason, and are still covered under the vehicle's warranty, and are within the VIN breakpoints provided below, should be checked for vehicle eligibility in the appropriate system listed below.

Important: Dealers/retailers are to confirm vehicle eligibility prior to beginning repairs by using the system(s) below. Not all vehicles within the above breakpoints may be involved.

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 and TIS 2 WEB website with the following calibration updates:

2008 Chevrolet Malibu; Saturn Aura: Use data version 11.0 for 2007 as of 10/31/07 or later, available on TIS 2 Web; and on TIS DVD version 12.0 / 2007 or later, mailed to dealers/retailers beginning 12/05/07.

To find the calibration, as noted in Step 2 of the following Service Procedure, select "Engine Control Module (ECM)" and then select "Engine Diagnostics".

If you cannot access the calibration, call the Techline Customer Support Center and it will be provided.

GMVIS or AS/400 (US Saturn) must be checked to determine if a specific vehicle requires this action. If the system indicates that Service Update Bulletin 07298 remains ‘open’ and ECM reprogramming has not taken place, reprogram the ECM using a Tech 2® scan tool with the calibration update from TIS 2 Web.

Tech 2 Pass-Thru Method for the Engine Control Module (ECM)

Notice: Before reprogramming, please check the battery condition to prevent a reprogramming error of any of the modules 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:

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 Tech 2® operating software is up to date.

1. Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Use an additional jump battery, if necessary. Only use approved Midtronics charger or Jumper Packs, etc. to maintain proper battery voltage during programming.
2. Reprogram the engine control module (ECM). Refer to SI and Service Programming System (SPS) documentation for ECM programming instructions, if required. To find the calibration, select "Engine Control Module (ECM)" and then select "Engine Diagnostics".
