Searching for a GENUINE Toyota Neutral Start Switch Assembly 84540-30270 with exact specifications and proven OEM compatibility? This neutral start switch is manufactured to Toyota’s original factory standards and is designed for select models, including Toyota Hilux, Toyota Hilux Surf, and Toyota Cresta, ensuring safe engine starting, accurate gear position detection, and reliable transmission system operation.

The neutral start switch (commonly known as the PNP switch) is a critical safety and control component in automatic transmission vehicles. Its primary function is to allow the engine to start only when the transmission is placed in Park or Neutral, preventing accidental vehicle movement. In addition, it communicates precise gear-position information to the vehicle’s electrical and engine management systems, supporting correct starter engagement, reverse light operation, and overall drivability.

Over time, wear, contamination, or internal electrical failure can cause the neutral start switch to malfunction. Common symptoms include intermittent or complete no-start conditions, the engine starting only in certain gear positions, incorrect gear indicator readings, malfunctioning reverse lights, or transmission-related warning lights. In such situations, replacing the faulty unit with the correct OEM part number 84540-30270 is essential to restore proper function and avoid further electrical or transmission-related issues.

This genuine Toyota switch assembly is a direct-fit OEM replacement, designed to install seamlessly using factory mounting points and connectors. Built with high-quality materials and precision electrical contacts, it offers long-term durability and consistent performance under daily driving as well as demanding usage conditions.

Installing an incorrect or non-compatible neutral start switch can lead to persistent starting problems, safety risks, fault codes, and premature wear of surrounding electrical components. Selecting a genuine Toyota component helps maintain factory reliability, system integrity, and peace of mind.

Before purchasing, always verify the vehicle model (Toyota Hilux, Toyota Hilux Surf, or Toyota Cresta), transmission type, and part number (84540-30270) to ensure precise fitment, correct operation, and dependable long-term performance you can trust.
