Service bulletins for the 2018 Toyota Sequoia

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. UNKNOWN OR OTHER; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; ELECTRICAL SYSTEM:SOFTWARE; FORWARD COLLISION AVOIDANCE; AIR BAGS. 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.

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.
