Got a letter today from Toyota Canada about a faulty electronic control unit (ECU) for 2012 - 2018 Avalon. Also for 2011 - 2014 Corolla and Matrix.
Problem:
The subject vehicles may be equipped with an electronic control unit (ECU) from a specific supplier designed to receive signals from crash sensors and deploy the air bags and seat belt pretensioners. The ECU may not have adequate protection against certain electrical noise that can occur in certain crashes, such as severe underride crashes. This can lead to incomplete or non deployment of the air bags and/or seat belt pretensioners. Airbags and seat belt pretensioners that do not deploy as intended can increase the risk of injury in a crash.
Solution:
Toyota is currently preparing the remedy. When the remedy becomes available, in most cases, Toyota dealers will install a noise filter between the airbag control module and its wire harness. in some cases, Toyota dealers may inspect the ECU to determine if the noise filter is necessary before installing it. The remedy will be free of charge to you
