C - Warning Lamp Does Not Come "ON" Steady
CHART C / part 1Chart C Air Bag Warning Lamp Does Not Comes On Stedy (1/2):
CIRCUIT DESCRIPTION
When the ignition switch is first turned "ON", "Ignition 1~ voltage is applied from the "0-22" fuse to the "AIR BAG" warning lamp which is connected to SRS warning lamp", terminal "A7". The "0-21" fuse apply system voltage to the "Ignition 1" inputs, terminals "A8". The SDM responds by flashing the "AIR BAG" warning lamp seven times. If "Ignition 1" is more than 16 volts, the "AIR BAG" warning lamp will come "ON" solid with no DTCs set.
