2001 Toyota 4Runner Parts Questions & Experts Answers

• Q: What are the essential steps to conduct a diagnostic system check and inspection of the Air Bag system after a collision on 2001 Toyota 4Runner?

  A: A diagnostic system check of the Air Bag system must happen as a first step following a collision. During inspection of uninvolved vehicles you must inspect the installed front passenger Air Bag assembly to check for cuts and cracks and mark discolorations. Vehicle front passenger Air Bag assemblies that did not deploy during a collision should be removed to check for matching damage while also examining wire harnesses and instrument panels for cuts and cracks since all detected issues need replacement. Additional inspection includes examination of instrument panel items and both connector components when Air Bags have deployed. The proper method needs to be followed during front passenger Air Bag assembly removal and replacement operations. Steering wheel pad and spiral cable need diagnostic system evaluation and visual damage assessment when they remain installed. To check for damage the steering wheel pad must be removed from vehicles that experienced a collision without Air Bag deployment to assess the horn button contact plate and steering wheel deformation status because these elements need replacement when deformed. Install the steering wheel pad so that it does not obstruct the steering wheel movement. During collision incidents inspect the spiral wire connector along with the wire harness of vehicles with active Air Bags. The SRS wire harness needs examination with the instrument panel wire harness assembly to detect connector breaks and cracks. Replacements are required for the Air Bag sensor assembly whenever it becomes deployed after an accident or is identified as faulty or has fallen off. Inspect the front Air Bag sensor for damage when the front fender suffers any impairment. If damage occurs do a diagnostic system check and replace the sensor immediately. The correct process for every installation and removal step must be followed when dealing with the front passenger Air Bag assembly and steering wheel pad alongside the Air Bag sensor assembly and front Air Bag sensor.
