SRS Sensor Software Update

On October 4, 2018, Toyota filed a Noncompliance Information Report (NCIR) with the National Highway Traffic Safety Administration (NHTSA) informing the agency of our intent to conduct a voluntary Safety (Noncompliance) Recall on certain 2018 – 2019 model year Sequoia and Tundra vehicles and certain 2019 model year Avalon vehicles.

Condition:
Due to inappropriate programming in the airbag electronic control unit (ECU), a fault may be erroneously detected during vehicle startup which would disable one or more of the sensors used to detect crashes. This could result in the side and curtain shield airbags and/or front and knee airbags not deploying as designed in a crash. As a result, there is an increased risk of injury in the event of a crash and regulatory requirements in certain markets may not be met.

NOTE: This condition will set one of the following Diagnostic Trouble Codes: B1610, B1615, B1630, B1635, B1690, or B1695.

Remedy:
For the involved vehicles, any authorized Toyota dealer will perform a software update on the center airbag sensor assembly FREE OF CHARGE to the customer.

NOTE: The remedy for J0X addresses the H0Y condition, the J0H condition, and the J0X condition. As a result, J0H is no longer active as of October 5, 2018 (note that H0Y is no longer active as of February 20, 2018, due to the launch of J0H). All vehicles involved in J0H and H0Y (whether or not J0H and/or H0Y were completed) are now included in Safety (Noncompliance) Recall J0X.

Covered Vehicles:
There are approximately 168,200 vehicles covered by this Safety (Noncompliance) Recall. Approximately 540 vehicles involved in this Safety (Noncompliance) Recall were distributed to Puerto Rico.

Owner Letter Mailing Date:
Toyota will begin to notify owners in late October 2018


Frequently Asked Questions

What is the condition?
Due to inappropriate programming in the airbag electronic control unit (ECU), a fault may be erroneously detected during vehicle startup which would disable one or more of the sensors used to detect crashes. This could result in the side and curtain shield airbags and/or front and knee airbags not deploying as designed in a crash. As a result, there is an increased risk of injury in the event of a crash and regulatory requirements in certain markets may not be met.

Are there any warnings that this condition exists?
If this condition has occurred, warning lights and messages will illuminate in addition to a warning chime. As a result, if you see these warning lights and messages, you may be experiencing the condition described above. You should contact your local authorized Toyota dealer for diagnosis and appropriate repair as soon as possible.

What should I do if my Airbag Warning Light illuminates?
The Airbag Warning Light is designed to come on when the engine switch is turned to the “ON” position during the ignition cycle check function. Under normal operation, it goes off after a few seconds. The warning light turning off after the check period means the system is operating as designed.** If the Airbag Warning Light (1) does not illuminate or (2) illuminates or remains illuminated after the few second check period, you may be experiencing this condition, and the side and curtain shield airbags and/or front and knee airbags may not deploy as designed in a crash. Please contact your local authorized Toyota dealer promptly for diagnosis and appropriate repair. If the warning lamp illumination is related to the condition covered by this Safety Recall, the inspection and potential repair will be performed at no charge to you.

What is Toyota going to do?
Toyota will send an owner notification by first class mail starting in late October 2018, advising owners to make an appointment with their authorized Toyota dealer to have a software update performed to correct this condition FREE OF CHARGE.

I previously received letters from Toyota about software updates for my vehicle. Do I still need to get this update completed?
Yes. This is an important Safety (Noncompliance) Recall. The previous software changes (Safety (Noncompliance) Recall designated by Toyota as “J0H” and Special Service Campaign designated by Toyota as “H0Y”) address different issues relating to the Vehicle Stability Control System, and an incorrect value being recorded for one data item in the Event Data Recorder. This recall revises the software in the Center Airbag Sensor Electronic Control Unit for all of these conditions.

If I had Safety (Noncompliance) Recall J0H and/or Special Service Campaign H0Y performed, do I still have to get this recall performed?
Yes. This is an important Safety (Noncompliance) Recall. The software update in both Safety (Noncompliance) Recall J0H and Special Service Campaign H0Y does not address the condition in this Safety (Noncompliance) Recall.

If I have this Safety (Noncompliance) Recall J0X completed, do I still have to complete Safety (Noncompliance) Recall J0H and/or Special Service Campaign H0Y?
No. The updated software that Toyota developed for Safety (Noncompliance) Recall J0X also addresses the condition in Safety (Noncompliance) Recall J0H and Special Service Campaign H0Y.

Which and how many vehicles are covered by this Safety (Noncompliance) Recall?
There are approximately 168,200 vehicles covered by this Safety (Noncompliance) Recall.

How long will the repair take?
The repair takes approximately one hour. However, depending upon the dealer’s work schedule, it may be necessary to make the vehicle available for a longer period of time.

What if I have additional questions or concerns?
If you have additional questions or concerns, please contact the Toyota Customer Experience Center at 1- 888-270-9371 Monday through Friday, 7:00 am to 7:00 pm, Saturday 7:00 am to 4:30 pm Central Time.
