AIR BAG Indicator Does Not Come ON

SIR Schematics:

CIRCUIT DESCRIPTION
When the ignition is turned ON the Inflatable Restraint Sensing And Diagnostic Module (SDM) flashes the AIR BAG indicator seven times. The SDM performs diagnostic tests on the SIR system and then turns the AIR BAG indicator OFF if no SIR malfunctions exist. If the ignition 1 voltage is outside of the normal operating range (9-16 volts), the SDM will turn the AIR BAG indicator ON with no DTCs present.
