ECE Noncompliance - Body Control Module Lighting Software (Export)

General Motors has decided that certain 2007 Cadillac Escalade export vehicles fail to conform to ECE R48. On these vehicles, the calibration of the body control module (BCM) may cause the following conditions:

1.) When the headlamps are off and the flash-to-pass switch is activated, the instrument panel’s cluster high beam telltale will illuminate but the high beam headlamps will not illuminate.

2.) The fog lamps cannot be turned on while the high beam headlamps are activated.

3.) If the right/left turn signal switch is activated while the brake switch is activated, a towed trailer’s brake lamps and the left/right turn signal lamps will illuminate and the trailer’s right/left turn signal lamp will flash. ECE trailer lamp functional requirements specify separate amber turn signal lamps and red stop lamps.

Dealers are to reprogram the BCM.

Involved are certain 2007 Cadillac Escalade vehicles built within these VIN breakpoints:

Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using the GM Vehicle Inquiry System (GMVIS) below. 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 sent directly to dealers. Dealers will not have a report available if they have no involved vehicles currently assigned.

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.

No parts are required for this recall.

Reprogram the body control module (BCM). Refer to the instructions below.

Tech 2 Pass-Thru Method for the Body Control Module (BCM)

Important: If Tech 2 Legacy or J2534 Pass-Thru programming fails, call Techline Customer Support Center (TCSC) at 1-800-828-6860 (English) or 1-800-503-3222 (French). A "Candi" module is necessary.

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 Techline Tech 2® scan tool and TIS 2 Web with the calibration update. Use TIS 2 Web version 8.0 for 2007 (available on 08/07/07). If you cannot access the calibration, call the Techline Customer Support Center at 1-800-828-6860 (English) or 1-800-503-3222 (French) and it will be provided.

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 TIS terminal 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 body control module (BCM). Refer to SI and Service Programming System (SPS) documentation for BCM programming instructions, if required.

Submit a Product Recall Claim with the information indicated below:

Refer to the General Motors WINS Claims Processing Manual for details on Product Recall Claim Submission.

Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the attached sample letter.

All unsold new vehicles in dealers' possession and subject to this recall must be held and inspected/repaired per the service procedure of this recall bulletin before customers take possession of these vehicles.

Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward.

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 provided in this bulletin for your use in contacting customers. Recall 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 recall enters your vehicle inventory, or is in your dealership for service in the future, you must take the steps necessary to be sure the recall correction has been made before selling or releasing the vehicle.

Dear General Motors Customer:

General Motors has decided that certain 2007 model year Cadillac Escalade export vehicles fail to conform to ECE R48. As a result, GM is conducting a safety recall. We apologize for this inconvenience. However, we are concerned about your safety and continued satisfaction with our products.

Important: 

Why is your vehicle being recalled?

The calibration of the body control module on your vehicle may cause the following conditions:

1.) When the headlamps are off and the flash-to-pass switch is activated, the instrument panel’s cluster high beam telltale will illuminate but the high beam headlamps will not illuminate.

2.) The fog lamps cannot be turned on while the high beam headlamps are activated.

3.) If the right/left turn signal switch is activated while the brake switch is activated, a towed trailer’s brake lamps and the left/right turn signal lamps will illuminate and the trailer’s right/left turn signal lamp will flash. ECE trailer lamp functional requirements specify separate amber turn signal lamps and red stop lamps.

What will we do?

Your GM dealer will reprogram the body control module. This service will be performed for you at no charge . It is likely that your dealer will need your vehicle longer than the actual service correction time of approximately 25 minutes because of service scheduling requirements.

What should you do?

You should contact your GM dealer to arrange a service appointment as soon as possible. Bring the enclosed customer reply form with you when you visit your dealer. The form identifies the repairs required. If you no longer own this vehicle, please let us know by completing the form and mailing it back to us.
