SUPPLEMENTAL RESTRAINT SYSTEM 9J±6
There is a shorting clip on the passenger air bag
assembly connector which connects to the SRS harness.
The shorting clip shorts across the passenger air bag
assembly circuit when the passenger air bag assembly
connector is disconnected. The circuit to the passenger
air bag assembly is shorted in this way to help prevent
unwanted deployment of the air bag when servicing the
passenger air bag assembly, the instrument panel or
other SRS components.

Steering Column
The steering column absorbs energy and is designed to
compress in a frontal crash to decrease the chance of
injury to the driver.
431R200006
Knee Bolster
The knee bolsters are used to absorb energy to protec
knees and control the forward movement of the vehicle's
front seat occupants during a frontal crash, by limiting leg
movement.

Definition
Air Bag
An inflatable cloth cushion designed to deploy in certain
frontal crashes. It supplements the protection offered by
the seat belts by distributing the impact load more evenly
over the vehicle occupant's head and torso.
Asynchronous
Performed in a nonperiodic fashion, (i. e., no defined time
or interval).
(B+)
Battery voltage, (B+) The voltage available at the battery
at the time of the indicated measurement. With the key
ªONº and the engine not running, the system voltage will
likely be between 12 and 12.5 volts. At idle the voltage
may be 14 to 16 volts. The voltage could be as low as 10
volts during engine cranking.
Bulb Check
The SDM will cause the ªAIR BAGº warning lamp to flash
seven times and then go ªOFFº whenever the ignition
switch transitions to the ON position from any other
ignition switch position and no malfunctions are detected.
ªCONTINUOUS MONITORINGº
Tests performed by the SDM on the SRS every 100
milliseconds while ªIgnition 1º voltage is in the normal
operating voltage range at the SDM.
Data Link Connector (DLC)
Formerly ªDLCº a connector which allows communication
with an external computer, such as a scan tool.
Datum Line
A base line parallel to the plane of the underbody or frame
from which all vertical measurements originate.
