Chart B - "Air Bag" Warning Lamp Comes "ON" Steady

Circuit Description:
When the ignition switch is first turned "ON", "Ignition 1" voltage is applied from the "C- 10" fuse to "AIR BAG", warning lamp which is connected to "SRS Warning Lamp", terminal "7". The "C- 21" fuses apply system voltage to the "Ignition 1" inputs, terminals "12". The SDM responds by flashing the "AIR BAG" warning lamp 7 times. If "Ignition 1" is less than 9 volts, the "AIR BAG" warning lamp will come "ON" solid with no DTCs set.
