The inflatable restraint sensing and diagnostic module (SDM) maintains a reserved energy supply. The reserved energy supply provides deployment power for the air bags. Deployment power is available for as much as 10 seconds after disconnecting the vehicle power. Disabling the SIR system prevents deployment of the air bags from the reserved energy supply.
