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.
On/Off Switch Indicator Module: Operation
The passenger seat occupant simulator receives a multiplexed DC voltage signal from the passenger airbag on/off switch. The signal is then converted into a digital signal and sent to the occupant restraint controller.
With the passenger airbag On/Off switch in the OFF position, the occupant restraint controller provides a ground for the Passenger Air Bag Off indicator, and disables the passenger airbag.
With the passenger airbag On/Off switch in the ON position, the occupant restraint controller allows full operation of the passenger airbag.
