  • B1346 Description

    When the ignition switch is turned to ON, the Sensing and Diagnostic Module (SDM) will perform turn-on test to diagnose critical malfunctions within SDM itself.

    Upon passing these test ignition and deployment loop voltages are measured to ensure that they are within their normal voltage ranges. The SDM monitors the voltages at the driver low and the passenger low to detect shorts to ground or voltage in the deploy loops.

    The SDM checks the wiring connection to the driver airbag module by letting the infinitesimal current flow through the internal circuit and verify the resistance.

  • Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

    • Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
    • Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
    • Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
    • Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
    Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
