“Air Bag" Warning Lamp
Ignition voltage is applied to the “AIR BAG" warning
lamp when the ignition switch is at the ON or START
positions. The SDM controls the lamp by providing
ground with a lamp driver. The “AIR BAG" warning lamp
is used in the SRS to do the following:
1. Verify lamp and SDM operation by flashing SEVEN
(7) times when the ignition switch is first turned
“ON".
2. Warn the vehicle driver of SRS electrical system
malfunctions which could potentially affect the
operation of the SRS. These malfunctions could
result in nondeployment in case of a frontal crash or
deployment for conditions less severe than
intended.
The “AIR BAG" warning lamp is the key to driver
notification of SRS malfunctions. For proper lamp
operation, refer to the “SRS Diagnostic System Check"
in this section.

SRS Coil Assembly
The SRS coil assembly consists of two current carrying
coils. This is attached to the steering column and allow
rotation of the steering wheel while maintaining
continuous contact of the driver deployment loop to the
driver air bag assembly.
There is a shorting clip on the yellow 2–pin connector
near the base of steering column which connects the
SRS coil to the SRS wiring harness.
The shorting clip shorts to the SRS coil and driver air
bag assembly when the yellow 2–pin connector is
disconnected. The circuit to the driver air bag
assembly is shorted in this way to help prevent
unwanted deployment of the air bag when servicing the
steering column or other SRS components.
