2004 Toyota Matrix Parts Questions & Experts Answers

• Q: What are the essential steps to conduct a diagnostic system check on the Air Bag system after a collision on 2004 Toyota Matrix?

  A: A diagnostic system check of the Air Bag system becomes essential after any collision occurs. An evaluation of the instrument panel passenger Air Bag assembly should include visual inspection for cuts and minute cracks and marked discoloration in vehicles which did not participate in a collision. The inspection of vehicle assemblies following a collision employs several steps: evaluation of components, wire harness check for fractures and cuts and connector examination for damage. This evaluation is only required when the Air Bag fails to deploy. Examples of instrument panel or reinforcement damage include deformation or cracking so the affected parts must be replaced with new ones. The instrument panel and reinforcement of deployed-Air Bag vehicles require another inspection to verify that they have no deformation or cracking along with checking the connector and wire harness for damage. The diagnostic and visual check procedures for the front seat Air Bag assembly are identical whether the collision involvement occurred or the Air Bag deployed during the incident. The diagnostic check and visual inspection of the horn button assembly requires thorough examination of its steering wheel and contact plate to prevent installation interferences. An inspection of the Air Bag harness needs to be performed for all vehicles that experienced a collision to identify both breaks and damaged connectors. The Air Bag sensor assembly requires diagnosis followed by a sensor replacement of the center component when it has deployed. Evaluation of the side Air Bag sensor assembly should be performed similarly to check for deployment conditions where failure requires replacement. Test the seat position sensor then examine it for damage while the front Air Bag sensor requires intense examination for any damage that can happen following damage to the vehicle front area. The inspection process should include an examination of the paint for deterioration and the brackets and case for damage and connector status.
