Subject: Safety Recall ESG (Supplemental Action to E0G) – Remedy 2003-2004 Model Year Avalon Vehicles Supplemental Restraint System (SRS) Electronic Control Unit (ECU) In January, 2015, Toyota filed a Defect Information Report (DIR) with the National Highway Traffic Safety Administration (NHTSA) informing the agency of our intent to update Safety Recall #E0G remedy to include the installation of a sub-wire harness and a replacement SRS ECU for 2003-2004 model year Avalon vehicles. Toyota has completed the remedy parts and owner mailing preparations and will begin notifying owners of covered vehicles beginning late March, 2016. Condition: The SRS ECU in these vehicles could have been manufactured with integrated circuits (ICs) that are susceptible to internal short circuiting when exposed to certain electrical noise from various vehicle electrical components. If internal short circuiting occurs, the front airbag(s) and/or seat belt pretensioner(s) could inadvertently deploy. An airbag that deploys inadvertently can, under some circumstances, increase the risk of injury and the possibility of a crash. Remedy: Toyota dealers are requested to install the sub-harness (filter), if not previously installed as part of Safety Recall E0G, and replace the SRS ECU at NO CHARGE to the vehicle owner. Covered Vehicles: There are approximately 119,140 vehicles covered by the original Safety Recall E0G in the U.S. Vehicles that previously received both a sub-wire harness and SRS ECU are not included in the Supplement Safety Recall ESG. Owner Letter Mailing Date: Toyota will send a remedy notification by first class mail to owners of vehicles covered by this safety recall beginning in late March, 2016.
