Customer Satisfaction - Modification to Improve Side Impact Protection

Subject:07003B -- Modification to Improve Side Impact Protection

Models:2007 Buick Allure, LaCrosse



The service procedure and claim information sections in this bulletin have been revised to include an inspection procedure and labor code. There may be a few vehicles that were repaired before shipment to dealerships. Please discard all copies of bulletin 07003A, issued March 2007.


Condition

2007 model year Buick Allure and LaCrosse vehicles not only meet, but exceed government standards for side impact protection. GM recently introduced into production, changes that add to that protection, including a revised wiring harness that provides a more protected path for the wires that send the signal to inflate the side impact airbag. GM is making similar changes to vehicles built before the production change.

Correction

To enhance the side impact protection, dealers are to modify both front door panels and install additional energy-absorbing material, if necessary, and also update the wiring harness in the door. The wiring harness update provides a more protected path for the wires that send the signal to inflate the side impact airbag. Without this wiring harness update, under certain crash conditions, the side impact airbag may not deploy.

Vehicles Involved

Involved are certain 2007 Buick Allure and LaCrosse vehicles built within these VIN breakpoints:

Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using 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 dealers - GM DealerWorld Recall Information

-- Canadian dealers - GMinfoNet Recall Reports

-- Export dealers - sent directly to dealers

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 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

Parts required to complete this program are to be obtained from General Motors Service and Parts Operations (GMSPO). Please refer to your "involved vehicles listing" before ordering parts. Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency situation, parts should be ordered on a CSO = Customer Special Order.

Service Procedure

Tools Required

J 38778 Door Trim Pad Clip Remover

Caution: When performing service on or near the supplemental inflatable restraint (SIR) components or the SIR wiring, the SIR system must be disabled. Failure to observe the correct procedure could cause deployment of the SIR components. Serious injury can occur. Failure to observe the correct procedure could also result in unnecessary SIR system repairs.

Caution: Do not strike or jolt the inflatable restraint side impact sensor (SIS). Before applying power to the SIS make sure that it is securely fastened. Failure to observe the correct installation procedures could cause SIR deployment, personal injury, or unnecessary SIR system repairs.

The inflatable restraint sensing and diagnostic module (SDM) maintains a reserved energy supply. The reserved energy supply provides deployment power for the airbags if the SDM loses battery power during a collision. Deployment power is available for as much as 1 minute after disconnecting the vehicle power. Waiting 1 minute before working on the system after disabling the SIR system prevents deployment of the airbags from the reserved energy supply.

Important: Skip Steps 17.0-17.24 if the vehicle is NOT equipped with roof-mounted side impact air bags. Vehicles without roof-mounted side impact airbags will NOT have the side impact sensor (SIS) harness. Review and complete the door trim panel and door energy absorber block service procedure in this bulletin.

Important: Perform this procedure on both the driver and passenger side front side door.

  1. Disable the SIR system. Refer to SIR Disabling and Enabling in SI.
