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.
Side Air Bag Control Module
On vehicles equipped with side air bags, Side Impact Air Bag Control Modules (SIACM) are located below front door opening, in front of "B" pillar. SIACM performs self-diagnostics and circuit tests to monitor system function. SIACM reports to ORC once every second. If any fault exists, SIACM will request ORC to turn air bag indicator light on. ORC will send a message via PCI bus circuit to Electro-Mechanical Instrument Panel (EMIC) to turn air bag indicator light on. For additional information on air bag system, see AIR BAG RESTRAINT SYSTEMS article in RESTRAINTS.
