501-20B-4 Occupant Restraints — Passive — Supplemental Air 501-20B-4
Bag System
DESCRIPTION AND OPERATION (CONTINUED)
The passenger air bag module is located above
the glove compartment and is integrated into the
instrument panel to provide an unobtrusive
appearance. The cover is a one-piece moulding
held by clips and a short retaining strap. As the
air bag deploys, the cover is forced free of the
clips, but remains attached to the instrument
panel by the short retaining strap.
The purpose of the inflator is to generate the gas
needed to fill the air bag. It consists of a high
strength steel casing filled with a solid propellant
charge and an electrically activated Igniter. The
igniter is activated by a signal from the air bag
control module, which in turn ignites the
propellant charge. The very rapid burning of the
propellant produces sufficient gas to fill the air
bag(s). As the gases expand they cool,
preventing heat damage to the air bag. The driver
air bag module has one inflator and an air bag,
with a filled volume of 30 litres. The passenger air
bag module has a single inflator and an air bag
with a filled volume of 60 litres.
The air bag(s) are a one-piece woven item with a
silicon coating to provide flame and heat
protection in the vicinity of the inflator.
The SRS will communicate concerns detected
during a driving cycle or after initial key ON by
means of a warning indicator located in the
instrument cluster.
If a concern is detected, the air bag control
module will communicate by flashing the warning
indicator to give a lamp fault code (LFC). A
diagnostic trouble code (DTC) is logged by the air
bag control module in a non-volatile memory. For
additional information,
refer to Diagnosis and Testing in this section.
