Troubleshooting Light Indicator of SMI Air Force One that Stays on All the Time

Question:

The indicator light stays on all the time on my 2018 Ram 1500. Could it be the sensor, can i test it with magnet or a piece of metal

The switch on the actuator for the Air Force One # SM99243 is a reed switch. It detects the presence of a magnet on the inner part of the actuator. When the magnet is near the switch the light is off. If you removed the reed switch and used a magnet you could simulate the activation and determine if the problem is the switch or the actuator. You also should try moving the switch on the actuator as it may need adjustment. If possible move the switch away from the air line as much as you can.
