SPECIAL SERVICE CAMPAIGN (K0B)
**Non-Toyota-Approved Modification - Owner Acknowledgment Form**
Certain 2018 -2019 MY Tacoma and Tundra - Millimeter Radar Wave Sensor
Important Information
Your vehicle is involved in Special Service Campaign K0B. It is 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 brief and limited vehicle slowing. The remedy involves an update to
the PCS software and application of sealer to the millimeter wave radar sensor in the front grille. Also, in the
rare case that the vehicle is currently exhibiting the condition, dealers will diagnose the sensor and replace it,
as necessary, FREE OF CHARGE.
However, because your vehicle has non-Toyota-approved modifications as noted below, PCS and Dynamic
Radar Cruise Control (DRCC) may not operate as designed regardless if this free remedy is performed. For
example:
• 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.
Owner Acknowledgement
I understand that, due to non-Toyota approved modifications on my
vehicle, PCS and DRCC may not operate as designed. I have been
advised that, when the dealer performs the remedy for Special Service
Campaign K0B, PCS will be set to “OFF”, PCS will be configured to
retain the last setting following a key cycle. Also, a notification label
instructing the driver not to use DRCC will be applied to the
dashboard. Toyota recommends the PCS and DRCC system NOT be

used when non-Toyota-approved modifications are installed on the
vehicle. I have also been advised that constant speed control mode
should be used instead of DRCC if cruise control is used. If the vehicle
is returned to factory condition, the PCS and DRCC systems can be
used.
For more information about the PCS system on how to use constant
speed control mode refer to section 4-5 of this owner’s manual.
