• Q: How to replace the Air Bag Sensor for Side Impact on 2004 Chevrolet Impala?

  A: Start by disabling the SIR system before you replace the Inflatable Restraint Side Impact Sensor. A safe power-up of the inflatable restraint side impact sensor (SIS) requires careful checking of its secure fastening as striking or jolting the SIS before power application risks accidental deployment of the system or possible injuries. The inflatable restraint side impact sensor repair requires removal of center pillar lower trim followed by disconnecting the wiring harness connector from the side impact sensor through uninstalling the yellow 2-way connector position assurance (CPA) attached to the side impact sensor's inflatable restraint harness. Remove the side impact sensor from the center pillar after loosening its 2 fasteners. Benchmark a clean mounting surface before securing the new side impact sensor to the center pillar using 10 N.m (89 lb in) torque on both fasteners. Use hand tools to install the CPA onto the side impact sensor's yellow 2-way connector after connecting this harness to the sensor. After installation of the center pillar lower trim complete the SIR system activation steps.
