Original Publication Date: February 20, 2018

To:	All Toyota Dealer Principals, General Managers, Service Managers, and Parts Managers
Subject:	Safety (Noncompliance) Recall J0H – Remedy Notice Certain 2018 Model Year Sequoia Certain 2018 Model Year Tundra Software Update for Vehicle Stability Control System (Center Airbag Sensor Assembly Software Update)

 

On February 20, 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 model year Tundra and Sequoia vehicles.  

 

Condition

In the involved vehicles, there is a possibility that a vehicle diagnostic function may unnecessarily turn off the Vehicle Stability Control System and affect other systems. If this occurs, warning lights and messages will be displayed, and a warning chime will sound. Turning off Vehicle Stability Control could increase the risk of a crash.

NOTE: This condition will set Diagnostic Trouble Code C1435 – “Yaw Rate Senor Internal Circuit” stored.

 

Remedy

For the involved vehicles, any authorized Toyota dealer will perform a software update on the center airbag sensor assembly at NO CHARGE to the customer.

NOTE: The remedy for J0H addresses both the H0Y condition and the J0H condition. As a result, Special Service Campaign H0Y is no longer active as of February 20, 2018. All vehicles involved in Special Service Campaign H0Y (whether H0Y was completed or not) are now included in Safety (Noncompliance) Recall J0H.

 

Covered Vehicles

There are approximately 64,900 vehicles covered by this Safety (Noncompliance) Recall. There were approximately 90 vehicles distributed to Puerto Rico involved in this Safety (Noncompliance) Recall.

Model Name	Model Year	Production Period
Sequoia	2018	Early August 2017 – Early February 2018
Tundra	2018

 

Owner Letter Mailing Date

Toyota will begin to notify owners in mid-March 2018. A sample of the owner notification letter has been included for your reference.

Toyota makes significant effort to obtain current customer name and address information from each state through industry resources when mailing owner letters. In the event your dealership receives a notice for a vehicle that was sold prior to the Safety (Noncompliance) Recall announcement, it is the dealership’s responsibility to forward the owner letter to the customer who purchased the vehicle.

Please note that only owners of the covered vehicles will be notified. If you are contacted by an owner who has not yet received a notification, please verify eligibility by confirming through TIS prior to performing repairs. Dealers should perform the repair as outlined in the Technical Instructions found on TIS.

 

New Vehicles in Dealership Inventory 

There are approximately 24,600 vehicles in new dealer inventory as of February 19, 2018.

Under Title 49, Section 30112 of the United States Code, a dealer cannot sell, offer for sale, or introduce or deliver for introduction in interstate commerce a new motor vehicle when it is aware that the vehicle does not comply with an applicable Federal Motor Vehicle Safety Standard or contains a defect related to motor vehicle safety.  Further, 49 Code of Federal Regulations §577.13 requires us to provide the following advisory:  It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect or noncompliance is remedied.  Toyota reimburses dealers for flooring costs associated with new vehicles held in dealership inventory until the recall remedy becomes available.  Toyota provides these flooring reimbursements at 60 day intervals.  Toyota reserves the right to withhold or charge-back any flooring reimbursement funds that may have been paid to the dealer if it determines that a new vehicle subject to a safety (noncompliance) recall was sold without first being remedied. Vehicle Safety (Noncompliance) Recall completion should always be verified through TIS. We request your assistance to ensure involved vehicles are identified and not delivered prior to performing the remedy.

 

NOTE: Dealers can identify if any of their new and used inventory has any open campaigns in the Vehicle Inventory Summary available in Dealer Daily (https://dealerdaily.toyota.com/).

 

Inspection Reminder Mirror Hang Tags for Covered Vehicles in New Dealer Stock

To easily recognize vehicles involved in this Safety (Noncompliance) Recall, each dealership should utilize Inspection Reminder Hang Tags. Inside the vehicle’s glove box are stickers containing the VIN. Apply one of these stickers to the hang tag and install the hang tag in the vehicle. A sample copy of the Inspection Reminder Hang Tag has been included for your reference.

NOTE: Dealerships can order hang tags from the Material Distribution Center (MDC).

Part Number	Description	Quantity
00411-140003	Inspection Mirror Hang Tag	25 Per Pack

 

             

Pre-Owned Vehicles in Dealer Inventory

To ensure customer satisfaction, Toyota requeststhat dealers complete this Safety (Noncompliance) Recall on any used vehicles currently in dealer inventory that are covered by this Safety (Noncompliance) Recall prior to customer delivery. However, if the campaign cannot be completed (for example, due to remedy parts availability), delivery of a covered vehicle is acceptable if disclosed to the customer that the vehicle is involved in a Safety (Noncompliance) Recall. 

Toyota expects dealers to use the attached Customer Contact and Vehicle Disclosure Form to obtain vehicle buyer information. Dealers are expected to provide a copy of the completed form, along with the most current FAQ, to the vehicle buyer. Toyota and the dealer may use this information to contact the customer when the remedy becomes available.

Keep the completed form on file at the dealership and send a copy to quality_compliance@toyota.com. In the subject line of the email, state “Disclosure Form J0H” and include the VIN. 

NOTE: Dealers can identify if any of their new and used inventory has any open campaigns in the Vehicle Inventory Summary available in Dealer Daily ( https://dealerdaily.toyota.com/ ).

 

Toyota Certified Used Vehicle (TCUV)

The TCUV policy prohibits the certification of any vehicle with an outstanding Safety Recall, Special Service Campaign, or Limited Service Campaign.  Thus, no affected units are to be designated, sold, or delivered as a TCUV until all applicable Safety Recalls, Special Service Campaigns, and Limited Service Campaigns have been completed on that vehicle.

 

Toyota Rent-A-Car (TRAC) & Service Loaners

Toyota requests that dealers remove all TRAC and Service Loaner vehicles from service that are covered by a Safety (Noncompliance) Recall unless the defect has been remedied.

 

Technician Training Requirements

The repair quality of covered vehicles is extremely important to Toyota. All dealership technicians performing this repair are required to successfully complete the most current version of the E-Learning course “Safety (Noncompliance) Recall and Service Campaign Essentials”. To ensure that all vehicles have the repair performed correctly, technicians performing this repair are required to currently hold at least one of the following certification levels:

• Toyota Certified (any classifications)
• Toyota Expert (any classifications)
• Master
• Master Diagnostic Technician

Always check which technicians can perform the repair by logging on to https://www.uotdealerreports.com. It is the dealership’s responsibility to select technicians with the above certification level or greater to perform this repair. Carefully review your resources, the technician skill level, and ability before assigning technicians to this repair.  It is important to consider technician days off and vacation schedules to ensure there are properly trained technicians available to perform this repair at all times.

 

Remedy Procedures

Refer to TIS for Technical Instructions on repair.  Conduct all non-completed Safety (Noncompliance) Recalls and Service Campaigns on the vehicle during the time of appointment.

 

Repair Quality Confirmation

The repair quality of covered vehicles is extremely important to Toyota.  To help ensure that all vehicles have the repair performed correctly, please designate at least one associate (someone other than the individual who performed the repair) to verify the repair quality of every vehicle prior to customer delivery.

 

Warranty Reimbursement Procedure

Q1:	What is the condition?
A1:	In the involved vehicles, there is a possibility that a vehicle diagnostic function may unnecessarily turn off the Vehicle Stability Control System and affect other systems. If this occurs, warning lights and messages will be displayed, and a warning chime will sound. Turning off Vehicle Stability Control could increase the risk of a crash. NOTE: This condition will set Diagnostic Trouble Code C1435 – “Yaw Rate Senor Internal Circuit” stored.   Q1a: What is the Vehicle Stability Control (VSC) system?  A1a: The VSC system manages engine output and brake hydraulic pressure to enhance vehicle stability.   Q1a: Are there any warnings that this condition exists?

Q3:	I previously received a letter from Toyota about a software update for my vehicle.  Do I still need to get this update completed?
A3:	Yes. This is an important safety recall.  The previous software change (Special Service Campaign designated by Toyota as “H0Y”) addresses a different issue relating to an incorrect value being recorded for one data item in the Event Data Recorder.  However, both updates revise the software in the Center Air bag Sensor Electronic Control Unit. Q3a: If I had Special Service Campaign H0Y performed, do I still have to get this recall performed?
