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/System Description
The inflatable restraint sensing and diagnostic module (SDM) senses vehicle impacts and provides deployment signals to the air bags and anchor and/or retractor pretensioners when warranted. The SDM sets DTC B0052 after each command for deployment. DTC B0052 will latch and not clear after 3 commanded deployments by the SDM. And therefore the SDM has to be replaced using end of life disposal procedure.
