A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

| K0B_Non-Toyota-A | 2019-06-24. Service bulletin. FORWARD COLLISION AVOIDANCE. Non-Toyota-Approved Modification - Owner Acknowledgment Form: **Non-Toyota-Approved Modification - Owner Acknowledgment Form** Certain 2018 -2019 MY Tacoma and Tundra - Millimeter Radar Wave Sensor. 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. |

TSB: All 2016 ? 2018 model year Land Cruiser and 2018 model year Sequoia, Tacoma, and Tundra vehicles are equipped with a Pre-Collision System (PCS), also known as Automatic Emergency Braking (AEB) as part of Toyota Safety Sense. The Pre-Collision System (PCS) defaults its operating mode to ON after each ignition (IG) cycle. In some driving conditions, such as extended off-road use, driving with tire chains in adverse conditions, towing another vehicle, or when your vehicle is being towed, drivers should operate the vehicle with PCS OFF. Drivers may also prefer to maintain this setting after each IG cycle. If this functionality is requested, follow the procedure in this Service Bulletin to disable the PCS mode reset after each IG cycle. |
