B1348 GMC 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.
