Airbag, Omega - B
Supplement to "Airbag: Corsa - B, Astra - F, Vectra / Cavalier, Calibra" Checking Procedures, 4 / 93, KTA - 1676.
This Technical Information Bulletin describes the checking of the airbag using TECH 1 and program module Opel / Vauxhall Omega - B 1994 ECU. The program module Opel / Vauxhall Omega - B 1994 ECU is especially developed for the Omega - B for Model Year'94.
Introduction
This brochure describes in detail the checking of the airbag system installed in the Omega - B using TECH 1 and the newly developed Program Module Opel / Vauxhall 1994 ECU.
Airbag Safety Regulations
Note: Alterations relative to the Checking Procedures are printed in bold type.
General · All operations on the airbag system may only by performed by franchised Opel / Vauxhall dealers and authorized Opel / Vauxhall Service Dealerships and only by trained personnel.
· The telltale must illuminate when the ignition is switched on and extinguish after approx. 4 seconds.
· There is a fault in the system if the telltale does not illuminate when the ignition is switched on.
· If the telltale does not extinguish or illuminates while travelling, there is a fault in the airbag system. It must then be assumed that the airbag system is no longer functional.
· The airbag steering wheel may only be replaced by steering wheels approved by Opel / Vauxhall.
· The impact cushion of the steering wheel must not be cemented, covered or otherwise modified. It may only be cleaned with a dry or water - moistened cloth and with a cleaning agent approved by Opel / Vauxhall.
· The airbag does not replace the function of the safety belt. Passengers must still attach their safety belts to ensure optimal protection.
· The front seats must always be adjusted to the correct body size.
· Vehicles with co - driver airbag do not permit the installation of a child safety seat on the co - driver's seat.
· Sales of airbag components to third parties are not permitted.
· Subsequent installation of accessories In the zone affected by the co - driver's airbag is not permitted. Consoles for telephone receivers, can holders, cassette storage boxes, additional mirrors, etc., can be ripped off by deployment of the co - driver's airbag and propelled backwards.
· If the vehicle Is equipped with an airbag system with two deployment circuits (driver and co - driver), "co - driver" must be selected when programming with TECH 1.
Diagnosis · Airbag units and control units may only be checked using TECH 1.
· The diagnosis connection may only be used for connecting TECH 1.
· During checking operations on the wiring harness with test lamps or multimeters, the plug connection to the airbag units and control unit must be disconnected.
· Never perform measurements on the airbag units with test lamps or multimeters, as the test current may be too high and cause unintentional deployment.
Installation and Removal, Replacement
· If the airbag has been deployed in an accident, the control unit, airbag units and contact unit must be exchanged for new parts.
· If the wiring harness for the airbag system is damaged, the entire instrument panel wiring harness must be replaced. The airbag system wiring harness includes all leads which are connected to individual components of the airbag system. All leads belonging to the airbag system are identified by the yellow coating.
· Do not modify the airbag system wiring harness in any way at all.
· Before commencing operations on the airbag system, disconnect the battery negative terminal and mask the terminal; then wait 1 minute until the capacitor In the airbag control unit has discharged.
· When removing the steering wheel, fix the steering column in the 'straight ahead" position, to avoid destroying the contact unit when the steering wheel is reinstalled.
· Airbag units must always be stored with the cushion side facing upwards.
· If vehicle repairs persist for longer periods of time, non - deployed, removed airbag units must always be stored under lock and key.
· In general, the airbag system must not be modified in any respect.
· The airbag unit must not be treated with grease, cleaning agents or similar (aggressive materials).
· The airbag unit and control unit are sensitive to impact. If they have fallen from a height of more than 50 cm / 20 in., they must not be installed.
· For welding operations, the cable clamp of the welding unit must be connected immediately beside the welding point. The control unit must always be disconnected from the wiring harness and the plug connection disconnected from the inflator.
· The airbag units and the control unit must not be subjected to temperatures above 90 °C / 194 °F, even for brief periods of time.
· Damaged or defective individual parts must not be repaired but must always be replaced, and must be returned In a special set of the original packaging.
· The components of the airbag system must not be opened by force.
· Before installation, check once more that the battery is disconnected, the terminal is masked and the ignition key is in the 0 position.
· After connecting the battery, reprogram volatile memories (e. g. electric window winders, electric sun roof, dock and radio coding).
Transport and Storage
· Airbag units may only be purchased, transported and stored, according to the safety regulations, by the trained personnel of a franchised Opel/ Vauxhall dealer or authorized Opel / Vauxhall Service Dealership.
· In many countries, use of airbag units is subject to legislation. These national legal requirements must be observed.
· Only airbag units that cannot be deployed may be returned. These should be returned in a new set of their original packaging, ordered in advance.
Disposal
· Airbag units must be rendered useless according to Opel / Vauxhall regulations by electric deployment before scrapping.
· Airbag units may only be deployed in a vehicle as a fixed installation.
· Remove all loose objects beforehand from the expansion area of the airbag.
· Deployment with the doors dosed and side windows open.
· Deployment only on suitable empty ground.
· Use only the special deployment tool KM - 799.
· Bystanders who may be affected should be informed of the noise level.
· Stand in front of the vehicle; this also applies to uninvolved bystanders.
· Maintain a safe distance of approx. 10 m / 10 yards from the vehicle on deployment.
· Connect the voltage source last.
· Non - deployed airbag units must never be disposed of with "normal" refuse.
· If deployment fails, wait approx. 5 minutes before approaching the vehicle and disconnect the voltage source beforehand.
· Remove non - deployable airbag units and return them in a new set of their original packaging, ordered in advance.
· Allow deployed airbag unit to cool for 15 minutes before removal.
· Deployed airbag units can be disposed of with "normal" refuse.
Registration
Registration of airbag units and control units in conjunction with Vehicle Identification Numbers is necessary to ensure that the allocation of airbag units and control units to vehicles can always be ascertained. Therefore, each new airbag unit or control unit is accompanied on distribution by a registration card in various languages. These registration cards must be filled out by the dealer immediately on reception/installadon in the vehicle. A sticker with a bar code and a serial number is attached to the control unit. This sticker is to be attached to the registration card. The 11 - digit serial number (not the 14 - digit) on the airbag unit casing must be entered In the registration card by hand. The remainder must by filled out by hand. The card is then returned In the enclosed envelope.
Shown here is the trilingual registration card which is included in the packaging for airbag components.

Checking Equipment
· TECH 1
· Program module "Opel / Vauxhall Omega - B 1994 ECU"
· Electronic - Kit I KM - 609
· Multimeter MKM - 587 - A
Note: For checking the airbag wiring harness, use only the adapters from Electronic - Kt I KM - 609.
The short circuit bridges prevent unintentional triggering of the airbag when the plug connections of the airbag wiring harness are disconnected.
Use of test probes and metal wires (such as paper clips) in the wiring harness plugs is not permitted. This would deform the short circuit bridges and the safety functions would no longer be guaranteed.
