Unlock Position Sensor Signal Circuit

Unlock Position Sensor Signal Circuit 

DESCRIPTION 

The unlock position sensor is one of the components comprising the steering lock actuator. The sensor switch contact closes when the steering lock is
released. The steering lock release signal is then sent to the power source control ECU assembly. Receiving the signal, the ECU permits engine start.
(This prevents the engine from being started with the steering locked.)
