• Q: How to replace the Air Bag Sensor for Side Impact on 2003 Buick LeSabre?

  A: Commence the replacement process of Inflatable Restraint Side Impact Sensor (SIS) by disabling the SIR system. Check that the side impact sensor of the inflatable restraint is safety fastened to its position while also preventing any force on the part to avoid deployment or injury. You must first move the seat to forward extent before you remove the center pillar trim panel. Disconnect first the connector position assurance (CPA) from the SIS harness connector and proceed by removing the SIS harness connector from the SIS . Extract the SIS mounting fasteners from its position to remove the SIS from the center pillar sheet metal. After cleaning the mounting surface from dust and grease it is possible to install the SIS onto the center pillar sheet metal while tightening the mounting fasteners at 9 N.m (80 lb in). Fasten the SIS harness connector to its position on the SIS and mount the CPA onto the SIS harness connector. The SIR system will become operational only when you replace the center pillar trim followed by restoring the seat to its stock location.
