Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit Description
The rear side door actuator control module uses an optical sensor to monitor the sliding door position at all times. The optical sensor requires a 5 volt reference and reference return from the rear side door actuator control module. There are 2 signal circuits from the optical sensor to the rear side door actuator control module. The optical sensor sends pulses through both signal circuits to the power sliding door module whenever the sliding door is in motion. The optical sensor pulses allow the rear side door actuator control module to calculate the position of the sliding door at all times. The optical sensor signal circuits switch from 0.01 to 4.5 volts as the sliding door is moving.
