Q: What is the purpose of the Supplemental Restraint System (SRS),Air Bag and Air Bag Control Module on Toyota Camry and 2007 through 2015 Toyota Avalon?
A: First of all, the system comprises airbags in the steering wheel and instrument panel, impact sensors, and a diagnostic module. Some models also include knee, side, and curtain airbags. The airbag modules, containing the cushion and inflator, receive an electrical signal. The passenger airbag is above the glove compartment. The diagnostic module powers the system and checks its operation at start-up. Side and curtain airbags are activated by sensors during side impacts. Precautions include disarming the SRS before work, careful handling of modules, avoiding resistance measurement, and proper disposal.
