- The “Remedy” section has been updated with details on vehicles
with non-Toyota authorized modifications that have changed
features such as the ride height of the vehicle, the factory installed
position of the millimeter wave radar sensor, the grille, etc.
- A new section regarding the remedy procedure for modified
vehicles has been added.
- The “Warranty Reimbursement Procedure” has been updated
with claim filing details for modified 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.
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: The DRCC notification label is not available at this time. Until the label becomes
available, the remedy should be performed without applying this label. 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 non-Toyota-approved modifications the remedy WILL be performed:
·
·
·

Modifications that affect ride height, such as lift kits, and/or oversized wheels/tires.
Grille guards that DO NOT obstruct the sensor.
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 that obstruct the sensor.

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.
