Passenger Air Bag Module
Driver And Passenger Air Bag Module Inflator:
The driver, passenger and side air bag modules consist of the following components which cannot be disassembled:
^ inflator
^ bag
^ container
^ cover
The passenger air bag module is located above the glove compartment and is integrated into the instrument panel top to provide an unobtrusive appearance. The cover is a one piece moulding, which is attached to the instrument panel along its upper edge, the lower edge is attached to the instrument panel by two plastic retainers. As the air bag deploys, the cover is forced free of the retainers, but remains attached to the instrument pad panel along its upper edge.
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 electronic 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 bag. The drivers air bag module has one inflator and bag, with a filled volume of 55 litres. The passenger air bag module has two inflators and bag having a filled volume of 60 litres. The side air bag has a single inflator and a bag with a filled volume of 12 litres.
The 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 shape of the passenger and side air bag (when equipped) are tailored to the vehicle proportions.
The supplemental restraint system fitted to the vehicle will communicate faults/concerns by the air bag control module during a driving cycle or after initial key ON by means of a warning indicator contained within the instrument cluster.
If a concern is detected, the air bag control module will communicate by flashing the warning indicator to give a Diagnostic Trouble Code (DTC).
