High/Low Position Sensor
WARNING: This page is about a different car, the 2013 Land Rover LR4, 2012 Land Rover LR4, 2011 Land Rover LR4, and 2010 Land Rover LR4. However, it is still accessible from the selected car via links, so may be relevant.
The high/low position sensor converts the pivotal movement of the high/low fork into a PWM signal on the input. The PWM signal of the position sensor differs between high range and low range. The control module checks this signal and informs the driver, via the instrument cluster and the range change selection switch LED's, if a range change is in progress or has been completed.
The high/low position sensor is connected to the transfer box control module via a three-pin connector.
