What the reviewed source says
Start with the documented condition, not a parts guess.
NHTSA campaign 20V024000 includes certain 2015 to 2019 Toyota Corolla vehicles. Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2011-2019 Corolla, 2011-2013 Matrix, 2012-2018 Avalon, and 2013-2018 Avalon Hybrid vehicles. During certain crashes, the air bag electronic control unit (ECU) may malfunction, possibly disabling the deployment of the air bags and/or seat belt pretensioners. In the event of a crash, air bags and/or seat belt pretensioners that do not deploy as intended may increase the risk of injury.

What the official procedure directs
Toyota will notify owners, and dealers will inspect the ECU and install a noise filter between the air bag control module and its wire harness, as necessary, free of charge. Owners were notified of the safety risk beginning March 2, 2020. A second letter notifying owners of the remedy repair will be mailed between March 16, 2020 and June 27, 2020.
Safety recall eligibility is based on the VIN and campaign scope, not ordinary warranty mileage. Check the complete VIN even when the vehicle is outside its original warranty.

Check the complete VIN before arranging work
Enter the 17-character VIN in NHTSA's recall lookup and ask the manufacturer or an authorised dealer to confirm whether the campaign is open for this vehicle.
A year, make and model match does not prove that every vehicle is included. The VIN result controls eligibility.

Useful before authorizing work
Read the method beside the problem
These guides explain the safety and evidence checks that apply to this problem file.
Check recalls by VIN
A VIN search checks the displayed NHTSA records for an unrepaired safety recall associated with one vehicle. A model search shows only the wider campaign population.
Read guide ↗When a car is unsafe
A warning light does not always mean the same thing, but weak brakes or smoke leave little room for experimentation. Damaged tires and certain recall instructions can do the same.
Read guide ↗Why symptoms overlap
“It makes a weird noise” is useful human language. Diagnosis begins when that language is tied to the exact vehicle and its operating conditions.
