Service bulletin K0B-TI-050219

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.

TSB0026202023-12-26. 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.
