• Q: What are the crucial steps to perform after a collision involving the occupant classification ECU and Air Bag assemblies on 2005 Toyota 4Runner?

  A: It is mandatorily essential to initialize the occupant classification ECU after a vehicle collision when the ECU gets replaced or accessories are installed or the passenger seat gets reinstalled or replaced or the passenger Air Bag ON/OFF indicator light (OFF) activates when the seat is unoccupied or the vehicle requires repairs following an accident. Start with assessing the horn button assembly through a diagnostic system check followed by visual inspection for solidness and clearness; replace the device if any damage appears. The steering wheel assembly requires examination after vehicle collisions that prevent Air Bag deployment due to check for complete and deformed steering wheel assembly while also assessing components at horn button sections. A diagnostic check should be run on the instrument panel passenger left door Air Bag assembly followed by a visual inspection for possible defects that would require replacing the instrument panel. During post-collision inspections the needed assembly must be removed to assess whether the wire harness or connector suffered damage so replacement steps will follow as determined. The diagnostic check must be performed on the front seat Air Bag assembly with additional visual inspections for defects that may require a front seatback assembly replacement. Before returning to service inspect the assembly system for damage after a non-deployment incident. A diagnostic check followed by visual inspection of defects should be performed on curtain shield Air Bags before deciding to replace the front pillar garnish or roof headlining assembly. Check the connector for damage when you perform an inspection on a vehicle following a non-deployment crash of the Air Bag system. The technician should perform diagnostic checks for the Air Bag sensor assembly center, front, rear, and side. Replacement of components follows visual defect inspections which cover cracks and dents of the assembly and its connections. Checks should be performed on the seat position Air Bag sensor as well as the occupant classification ECU for indications of damage while inspecting wire harnesses and their connectors for cracks and breaks. You must always conduct procedures correctly during all component removals and installations.
