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

Production Period

Early August 2017 – Mid-December 2018

Approximate Total Vehicles
280,200
160,600

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.

NOTE: If a vehicle has non-Toyota-approved modifications that have changed the ride height of the vehicle
or the factory installed position of the millimeter wave radar sensor, the owner will be required to sign the
“Non-Toyota-Approved Modification - Owner Acknowledgment Form” before the remedy is performed. The
remedy for modified vehicles includes the following additional steps:
•
•
•

PCS will be set to “OFF”.
PCS will be configured to retain the last setting following a key cycle.
A notification label instructing the driver to use Constant Speed Control and not to use Dynamic Radar
Cruise Control (DRCC) will be applied to the dashboard.
Note: All dealers were mailed a supply of the DRCC notification labels on 5/24/2019. Additional stock of
these labels can be ordered from the Toyota MDC (part number is 214182323). Starting 5/30/2019, this
label SHOULD be applied when performing the remedy on Modified vehicles. Toyota will mail a copy of
the label to all owners that had the remedy performed on a Modified vehicle before the label was available.

•

An owner’s manual insert will be placed in the owner’s manual.

Not all vehicles with non-Toyota-approved modifications will have the remedy performed. Examples of nonToyota-approved modifications the remedy WILL be performed:
•
•

Modifications that affect ride height, such as lift kits, and/or oversized wheels/tires.
Toyota original equipment grilles installed on trucks that were not originally intended for the trim level of
the vehicle.

Examples of non-Toyota approved modifications on which the remedy can NOT be performed:
•
•
•
•
•

Aftermarket grilles
Grille guards
Winches
Light bars
Aftermarket steel bumpers

In these cases, if the owner restores the vehicle to its original design at his/her expense, the remedy will be
performed.
For additional information on identifying vehicles with non-Toyota-approved modification, and on which
vehicles with non-Toyota-approved modifications will have the remedy performed, refer to the K0B Modified
Vehicles ASM Job Aid.
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.
Customer Handling, Parts Ordering, and Remedy Procedures
Customer Contacts
Customers who receive the owner letter may contact your dealership with questions regarding the letter

Center (1-888-270-9371) - Monday through Friday, 7:00 am to 7:00 pm, Saturday 7:00 am to 4:30 pm Central
Time.

Remedy Procedures
Refer to TIS for Technical Instructions on repair. Conduct all non-completed Safety Recalls and Service
Campaigns on the vehicle during the time of appointment.
Modified Vehicles Handling Procedure
Assistant Service Managers (ASMs) should refer to TIS for the K0B Modified Vehicles ASM Job Aid for details
on identifying vehicles with non-Toyota-approved modifications that have changed the ride height of the
vehicle or the factory installed position of the millimeter wave radar sensor. Use this job aid to determine if
vehicles with the non-Toyota-approved modifications can be remedied, and information on the Non-ToyotaApproved Modification - Owner Acknowledgment Form, Owner’s Manual insert, and DRCC notification label.
Technicians should refer to TIS for the Technician Job Aid For Vehicles with Modifications for details on the
repair process for vehicles with non-Toyota-approved modifications that have changed the ride height of the
vehicle or the factory installed position of the millimeter wave radar sensor.
Note: The DRCC notification label has been updated so that it is a common label used for this campaign and
the Technical Service Bulletin titled “PCS and DRCC Permanent Disabling” / TSB number T-SB-0026-20. While
the labels are common, DO NOT use this TSB for vehicles being repaired under this Special Service Campaign
(K0B). As mentioned above, refer to the Technician Job Aid for vehicles with modifications covered by K0B.
This label can still be ordered through the MDC.
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.
