THE SERVICE PROCEDURE IN THIS BULLETIN HAS BEEN REVISED. PLEASE READ THE NEW SERVICE PROCEDURE IMMEDIATELY. DISCARD ALL COPIES OF BULLETIN 05122, ISSUED DECEMBER 2005. THIS PROGRAM EXPIRES DECEMBER 31, 2006.
Condition
For certain 2006 Chevrolet Impala and Monte Carlo vehicles with ABS (JL9) and 17 or 18 wheels (NW1/NW5/PFH/N99), a revised brake module calibration is available that can enhance the vehicle's antilock brake performance slightly by reducing minimum stopping distance on dry pavement. The braking performance of the vehicle meets the applicable Federal/Canada Safety Standard and all of GM's rigorous internal requirements, but GM has identified a performance improvement that we want to make available to customers.
Correction
Dealers are to reprogram the electronic brake control module (EBCM).
Vehicles Involved
Involved are certain 2006 Chevrolet Impala and Monte Carlo vehicles with ABS (JL9) and 17 or 18 wheels (NW1/NW5/PFH/N99) and built within the VIN breakpoints shown.
Important:
Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) prior to beginning program repairs. [Not all vehicles within the above breakpoints may be involved.]
For dealers with involved vehicles, a Campaign Initiation Detail Report (CIDR) containing the complete vehicle identification number, customer name and address data has been prepared and will be loaded to the GM DealerWorld (US) Recall Information, GMinfoNet (Canada) Recall Reports. Dealers will not have a report available if they have no involved vehicles currently assigned.
The Campaign Initiation Detail Report 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 program 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 program.
Parts Information
No parts are required for this program.
Service Procedure
Important:
Make sure that your Tech 2(R) is updated with the latest software before beginning the reprogram. Use instructions for Service Programming System.
1. Reprogram the electronic brake control module (EBCM), which may be listed as an ABS module in TIS, with updated software calibration. The new service calibration was released with TIS satellite data update, version 11.0 available October 31, 2005.
2. Relearn the tire pressure monitoring system as necessary.
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 Warranty. 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. Dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy Transportation guidelines.
Claim Information
Submit a Product Claim with the information shown.
Refer to the General Motors WINS Claims Processing Manual for details on Product Recall Claim Submission.
Customer Notification
General Motors will notify customers of this program on their vehicle (see copy of customer letter shown in this bulletin).
Dealer Program 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 December 31, 2006.
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. A copy of the customer letter is shown in this bulletin for your use in contacting customers. Program follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this program enters your vehicle inventory, or is in your dealership for service prior to December 31, 2006, you must take the steps necessary to be sure the program correction has been made before selling or releasing the vehicle.
