This switch is located on the rear differential lock actuator of your ute. Its job is to tell your vehicle's computer when the diff lock is engaged, which then turns on the corresponding light on your dash. Being located underneath the vehicle, these switches are constantly exposed to mud, water, and heat. The internal components can fail, leaving you with an inaccurate signal. If your diff lock light is flashing, staying on, or the diff lock won't engage at all, a faulty position switch is a common cause. Don't get caught out on the tracks; a non-functional diff lock can be the difference between driving out and getting recovered.
Please check the vehicle fitment guide to confirm compatibility with your vehicle. If you are unsure, contact us with your VIN for assistance.
