Service bulletin K0B_Non-Toyota-A
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.

NHTSA's summary
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.

| TSB002620 | 2023-12-26. Service bulletin. TSB: All 2020 ? 2023 model year 4Runner, 2018 ? 2022 model year Sequoia, 2018 ? 2023 model year Tacoma, and 2018 ? 2021 model year Tundra vehicles are equipped with Pre-collision System (PCS) and Dynamic Radar Cruise Control (DRCC) as part of the Toyota Safety Sense (TSS) package. The PCS and DRCC systems are designed to help mitigate a potential collision and maintain a pre-determined traveling distance. It is recommended to disable the PCS and DRCC systems on vehicles that have been modified (ride height, oversized wheels/tires, brush bars, etc.) in a way that potentially disrupts the functionality of these systems. Vehicle owner?s written consent is required before performing the calibration to permanently disable the PCS and DRCC systems. Follow the Repair Procedure in this bulletin to disable the PCS and DRCC systems. |
