The Inflatable Restraint Sensing and Diagnostic Module (SDM) monitors the front end sensor circuit of the inflatable restraint system for front impact detection. The SDM processes the signal provided by the front sensor to further support airbag deployment. The front sensor is an input only to the SDM and does not directly cause airbag deployment. When the ignition is turned ON, the SDM performs continuous diagnostic tests on the deployment loops to check circuit continuity and shorts to ground or voltage. If a malfunction is detected, a Diagnostic Trouble Code (DTC) will be stored.

Precautions for SRS “AIRBAG” and “SEAT BELT PRETENSIONER” Service
  • Never test the electrical connectors of airbags, side air curtain modules, or seat belts.
  • Never disassemble or modify seat belt pretensioners/retractors, adaptive load limiting retractors, seat belt inflators, and never test their electrical connectors.
  • Do not use electrical test equipment to check SRS circuits unless otherwise indicated in this service manual.
  • Before repairing the SRS, turn the ignition switch to OFF, disconnect both battery cables, and wait at least 3 minutes. For about 3 minutes after removing the cables, it is still possible for the airbag and seat belt pretensioner to deploy. Therefore, do not work on any SRS connector or cable until at least 3 minutes have passed.

Failure to follow these instructions may result in accidental deployment of these modules, increasing the risk of serious injury or death.
