What is the Sprinter Starter Lockout Solenoid SP428?
The Sprinter Starter Lockout Solenoid SP428 is a specialized component that serves as a safety mechanism in the starting systems of certain vehicles. Its primary function is to prevent the engine from starting unless specific conditions are met, which helps to thwart theft and unauthorized usage.
This solenoid works by controlling the flow of electrical current to the starter motor. When the ignition is turned on, the solenoid engages, allowing current to pass through to the starter, thereby enabling the engine to start. If the conditions for starting are not met—such as the vehicle being in gear or the brake pedal not being pressed—the solenoid will remain disengaged, preventing the engine from starting.
