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.
Restraint Control Module (RCM)
The RCM communicates on the ISO 9141 network. The RCM monitors and controls the supplemental restraint system (SRS). The SRS is designed to provide increased crash protection for front seat occupants. The RCM will deploy the vehicle air bags based on sensor input during a crash event. For additional information, refer to AIR BAG RESTRAINT SYSTEMS .
