Disarming
The Sensing and Diagnostic Module (SDM) can maintain enough voltage to cause air bag deployment for up to 10 minutes after the ignition is turned off and the battery is disconnected. Servicing the Supplemental air bag (SIR) system during this period may result in accidental deployment and personal injury. |
The inflatable restraint Sensing and Diagnostic Module (SDM) maintains a reserved energy supply. The reserved energy supply provides deployment power for the air bags if the SDM loses battery power during a collision. Deployment power is available for as much as one minute after disconnecting the vehicle power. Waiting one minute before working on the system after disabling the SIR system prevents deployment of the air bags from the reserved energy supply. |
