Circuit Description

When the ignition switch is first turned to ON, ignition voltage is supplied from the air bag fuse to find the sensing and diagnostic module (SDM) at the input terminal A1. The SDM responds by flashing the air bag indicator 7 times and then turning it OFF while the SDM performs tests on the SIR.
