Millimeter Wave Radar Sensor
Model / Years
2018 – 2019 Tacoma
2018 – 2019 Tundra

Approximate Total Vehicles

Condition
The involved vehicles are equipped with a Pre-Collision System (PCS) that may automatically apply the brakes
if the system detects a potential collision. Due to the mounting of one of the system’s sensors, it is possible
for water to enter the sensor. This can lead to PCS deactivation or inadvertent brake activation resulting in
limited deceleration for a short duration of time.
Please refer to the Owner’s Manual for additional information regarding the PCS system operation.
Remedy
Any authorized Toyota dealer will update the PCS software and apply sealer to the millimeter wave radar
sensor in the front grille. In the rare case that the vehicle is currently exhibiting the condition, dealers will
diagnose the sensor and replace the sensor, as necessary, FREE OF CHARGE.
Covered Vehicles
There are approximately 440,800 vehicles covered by this Special Service Campaign. Approximately 8,000
vehicles involved in this Special Service Campaign were distributed to Puerto Rico.

Owner Letter Mailing Date
Toyota will begin to notify owners in late March 2019. 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 Special Service Campaign 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.
Dealer Inventory Procedures
New and Used Vehicles in Dealership Inventory (In-Stock Vehicles)
To ensure customer satisfaction, Toyota requests that dealers complete this Special Service Campaign on any
new or used vehicles currently in dealer inventory that are covered by this Special Service Campaign 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 Special Service Campaign.
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 K0B” 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/). The Vehicle Inventory Summary
may take up to 4 hours to populate information for newly launched campaigns.
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.
