Recall - ECM Update for Fuel Sender OBD Diagnostics: Overview
# 08136: Product Emission - On-Board Diagnostic (OBD)-Fuel Level Sender-Reprogram Engine Control Module (ECM) (California Only)(May 13, 2008
Subject:
08136 -- On-Board Diagnostics (OBD) - Fuel Level Sender - Reprogram Engine Control Module (ECM)
Models:
2004-06 Chevrolet Silverado Chassis Cab, Suburban, Avalanche - California Only
2004-06 GMC Sierra Chassis Cab, Yukon XL - California Only Equipped With Dual Fuel Tanks
Condition
General Motors has decided to conduct a Voluntary Emission Recall involving certain 2004-06 Chevrolet Silverado chassis cab, Suburban, Avalanche; GMC Sierra chassis cab and Yukon XL model trucks, equipped with dual fuel tanks. The revised calibration includes changes to the Fuel Level Sender On Board Diagnostics (OBD) system that should be installed as soon as possible. Install the new calibration on all affected vehicles identified in this bulletin, including vehicles in new dealer inventory and any vehicles that return for service, for any reason. To verify if an updated calibration is required, refer to the following procedure in this bulletin.
Correction
Dealers are to reprogram the ECM with corrected calibrations.
Vehicles Involved
Involved are certain 2004-06 Chevrolet Silverado chassis cab, Suburban, Avalanche; GMC Sierra chassis cab and Yukon XL model trucks, equipped with dual fuel tanks and built within the VIN breakpoints shown above.
Important:
Dealers are to confirm vehicle eligibility prior to beginning repairs by using the GM Vehicle Inquiry System (GMVIS). Not all vehicles within the above breakpoints may be involved.
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 GM dealers - GM DealerWorld Recall Information
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
Do not attempt to order the calibration number from GMSPO. The calibration numbers are programmed into Control Modules via a Techline Tech 2 scan tool and the Techline Information System (TIS) 2000 terminal with the calibration update.
2004-05 Trucks
Use data version 8.0 for 2006 or later, broadcast to dealers on August 6, 2006 or TIS 2 Web version 8.0 for 2006; and on TIS DVD version 8.0 / 2006 or later, mailed to dealers beginning August 23, 2006. If you cannot access the calibration, call the Techline Customer Support Center and it will be provided.
2006 Trucks
Use data version 2.5 for 2006 or later, broadcast to dealers on February 19, 2006; and on TIS CD-ROM version 3.0 / 2006 or later, mailed to dealers beginning on March 15, 2006. If you cannot access the calibration, call the Techline Customer Support Center at and it will be provided.
Service Procedure
The "Required Field Actions" section of the GM Vehicle Inquiry System (GMVIS) must be checked to determine if a specific vehicle requires this action. If GMVIS indicates that Emission Recall 08136 remains 'open' and ECM reprogramming has not taken place otherwise after the TIS Broadcast or CD-ROM availability dates identified in this bulletin, reprogram the ECM using a Tech 2 scan tool with the calibration update from Techline Information System (TIS) 2000.
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(R) 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 Tech 2(R) 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.
3. CALIFORNIA VEHICLES ONLY: Install a Recall Identification Label. Also, for California vehicles complete a "Proof of Correction" certificate upon recall completion.
Recall Identification Label - California Vehicles Only
Place a Recall Identification Label on each vehicle corrected in accordance with the instructions outlined in this Product Recall Bulletin. Each label provides a space to include the recall number and the five-digit dealer code of the dealer performing the recall service. This information may be inserted with a typewriter or a ballpoint pen.
Put the Recall Identification Label on a clean and dry surface of the radiator core support in an area that will be visible to people servicing the vehicle.
When installing the Recall Identification Label, be sure to pull the tab to allow adhesion of the clear protective covering. Additional Recall Identification Labels for US dealers can be obtained from Dealer Support Materials by ordering on the web from DWD Store, www.gmdealerworld.com, and then click on the DWD Store link. Request Item Number S-1015 when ordering.
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 Warranties. The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period and involved in a product program 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. GM dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy Transportation guidelines.
Claim Information
Submit a Product Recall Claim with the information shown.
Customer Notification
General Motors will notify customers of this recall on their vehicle (see copy of customer letter shown in this bulletin).
In order to ensure full protection under the emission warranty, and the right to participate in future recalls, the customer notification letter recommends that customers have their vehicles serviced as soon as
possible. It also advises that failure to do so could legally be determined to be lack of proper maintenance. The vehicle may fail a state or local emission inspection test if the recall work is not completed.
