The flat rate times include 0.1 hours for administrative cost per unit for the dealership.
In the rare cases that the condition has occurred, if the diagnosis of the sensor determines the vehicle
requires replacement of the millimeter wave radar sensor, follow the technical instructions to determine if
the new sensor requires application of the sealer and an update to the calibration ID.

•

If the vehicle required replacement of the millimeter wave radar sensor, file two claims. On the first claim
file op code K0B005, K0B006, K0B007, K0B008, K0B009, K0B014, K0B015, K0B016, K0B017, or K0B018. On the
second claim file op code K0B888.

•
•
•

K0B888 is for replacement of the millimeter wave radar sensor and does not close the campaign.
File op codes in order listed above if sensor replacement was necessary.
For claims using the modified vehicle op codes a copy of the completed Non-Toyota-Approved
Modification - Owner Acknowledgment Form must be attached to the warranty claim.

NOTE: Refer to the tables in the “Parts Ordering Process” section to determine applicable part number.
Claim Filing Accuracy and Correction Requests
It is the dealer’s responsibility to file claims correctly for this Special Service Campaign. This claim filing
information is used by Toyota for various government reporting activities; therefore, claim filing accuracy is
crucial. If it has been identified that a claim has been filed using an incorrect Op Code or a claim has been
filed for an incorrect VIN, refer to Warranty Procedure Bulletin PRO17-03 to correct the claim.
Customer Reimbursement
Reimbursement consideration instructions will be included in the owner letter.

TOPIC
The note in A5 has been updated with details regarding the update of the “DRCC
notiifation label”.
The note in A5 has been updated with details regarding the availability of the
“DRCC notiifation label”.
A4b and A4c have been updated with details on vehicles with non-Toyota
authorized modifications such as grilled guards, winches, light bars, or
aftermarket steel bumpers. Vehicles with these modifications should not have
the remedy performed unless the vehicle is restored to its original condition.
Multiple questions have been added to address questions about non-Toyotaapproved vehicle 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.

The most recent update will be highlighted with a red box.
Q1:
A1:

What is the 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.

Q1a:

What is the function of the PCS?

A1a:

PCS detects potential collisions with obstacles like vehicles ahead or objects in the roadway
using a (front mounted) millimeter wave radar and inputs from other vehicle sensors. When
the system’s Electronic Control Unit (ECU) detects a potential collision, a warning message
will appear, a buzzer will sound, and the brakes may be automatically applied.

FAQ Page 1 of 5
© 2019 Toyota Motor Sales, USA

Q2:
A2:

Are there any warnings that this condition exists?
If PCS activation occurs without any obstacles ahead such as vehicles or objects in the roadway, you
may be experiencing the condition described above. If this occurs, the vehicle will sound a warning
buzzer and a message on the multi-information display will be displayed while PCS is activated. The
brakes could also be automatically applied, and Brake Assist Mode may be activated.
If PCS has become deactivated, various PCS warning lights and messages will be displayed in the
instrument cluster and multi-information display indicating that the PCS system is unavailable. To learn
more about the vehicle’s PCS, refer to section 4-5 of the owner’s manual.
PCS Activation*

PCS Disabled**

*Audible buzzer can be heard during PCS activation.
**PCS may become disabled temporarily during certain conditions. Please refer to the Owner’s Manual
for additional information regarding the PCS system operation.

Q3:
A3:

Q4:
A4:

What is Toyota going to do?
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.

My vehicle has non-Toyota-approved modifications; can this Special Service Campaign be performed?
If a vehicle has non-Toyota-approved 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., the
vehicle will need to be inspected to determine if the remedy can be performed.
NOTE: Toyota does not recommend modifying vehicles and cannot evaluate how non-Toyota
approved modifications could affect a vehicle’s operation.

Q4a:

On which vehicles with non-Toyota approved modifications will the remedy be performed?

A4a:

Examples of such non-Toyota approved modifications include:
•
•

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.

NOTE: Performing the remedy on these vehicles will not guarantee that the vehicle will operate
as originally designed. See Q5, below.

Q4b:

On which vehicles with non-Toyota approved modifications will the remedy NOT be
performed?

A4b:

Examples of such non-Toyota-approved modifications include:
•
•
•
•
•

Aftermarket grilles
Grille guards
Winches
Light bars
Aftermarket steel bumpers

NOTE: In these cases, if the owner restores the vehicle to its original configuration at his/her
expense, the remedy will be performed.

Q4c:

What can I do if my vehicle has non-Toyota approved modifications that DO NOT allow the
remedy to be performed?

A4c:

Toyota recommends that the non-Toyota-approved modifications be removed from the
vehicle. Once these non-Toyota approved modifications are removed, any authorized dealer
can perform the remedy.

Q5:
A5:

What does the remedy involve for vehicles with non-Toyota-approved modifications?
Dealers will perform all steps described in A3. The following additional steps will also be performed:
•
•
•
•
•

Prior to performing the remedy, the owner will be required to sign the “Non-Toyota-Approved
Modification - Owner Acknowledgment Form”.
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.
An owner’s manual insert will be placed in the owner’s manual.

Q6:

The dealership is requiring me to sign a form acknowledging the PCS and DRCC may not operate as
designed before performing the remedy, and they are turning off PCS. Why is this?

A6:

Your 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. As a result, PCS and DRCC may
not operate as designed even if this free remedy is performed.

Q7:
A7:

I was told my vehicles PCS and DRCC may not operate as designed. What does this mean?
Your vehicle has non-Toyota-approved modifications which may cause PCS and DRCC to not operate
as designed. Some examples of the PCS or DRCC not operating as designed are:
•
•

PCS may activate even if a collision is not likely.
PCS may not recognize a vehicle or a pedestrian when a preceding vehicle or pedestrian is ahead.
For more information on the effects of non-Toyota approved modifications on PCS and DRCC, go to
www.toyota.com/content/ebrochure/CFA_TSS_Precautions.pdf.

Q8:
A8:

How can I confirm that PCS is OFF?
While PCS is deactivated, the PCS warning light will be displayed in the instrument cluster and a
message will be displayed on the multi information display.
PCS Warning Light
and Warning Message

Q9:
A9:

I was advised not to use DRCC. Can I use cruise control?
