The 1B2493700046 is the complete ignition lock cylinder and electrical switch combination for compatible FOTON trucks. It is installed on the steering column and is operated by the vehicle’s unique mechanical key. This assembly performs several critical functions: it mechanically locks the steering column to prevent theft, and through its internal electrical contacts, it routes power to different vehicle systems as the key is turned through the standard positions (OFF, ACC, ON, START).
This component, part number 1B2493700046, is a sophisticated electromechanical device. The mechanical side includes a robust lock cylinder and tumbler mechanism that matches your key. The electrical side is a multi-circuit switch capable of handling the high current required for the starter solenoid while also providing “switched power” to the ignition, fuel system, and dashboard. The genuine 1B2493700046 is engineered for thousands of reliable cycles and is a fundamental part of both daily operation and vehicle security.
The 1B2493700046 assembly is the primary interface between the driver and the truck’s powertrain. Turning the key initiates a carefully sequenced process: powering the engine control unit, priming the fuel system, and finally engaging the starter. Its built-in steering lock is a critical anti-theft feature. Using the genuine OEM 1B2493700046 ensures all these functions work in perfect harmony, providing the reliability expected in commercial vehicles and maintaining the factory security standards.
Acts as the main gateway for electrical power, safely directing current to the starter circuit, ignition coil, fuel pump, and accessory systems in the correct sequence to start and run the engine.
Provides a mechanical theft deterrent by physically locking the steering wheel in place when the key is removed, an essential security feature for any commercial vehicle.
Engineered to withstand the daily stress of being turned on and off multiple times a day over many years. The contacts in the 1B2493700046 are designed to resist wear, arcing, and corrosion.
