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 2 minutes after disconnecting the vehicle power. Disabling the SIR system prevents deployment of the air bags from the reserved energy supply.
