Ignition switch replacement

SIR DISABLE:
DRIVER SIDE
Many service procedures require the air bag system to be disabled to prevent accidental deployment. The air bag system can maintain sufficient voltage to cause deployment for up to 2 minutes after the ignition switch is turned off, the battery ground cable is disconnected or the DERM fuse is removed. If the inflator module is disconnected from the deployment loop by the following procedure, service can begin immediately without waiting for the 2 minute time period to elapse.

1. Turn steering wheel so that vehicle wheels are pointed straight ahead.
2. Turn ignition switch to Lock position and remove key.
3. Remove air bag fuse from fuse block.
4. Remove steering column filler panel.
5. Remove Connector Position Assurance (CPA) and disconnect yellow two-way connector at base of steering column, Fig. 1.

PASSENGER SIDE

1. Remove air bag fuse from fuse block.

SIR ENABLE:
Driver Side

1. Turn ignition switch to LOCK and remove key.
2. Connect yellow two-way connector and install connector position assurance (CPA).
3. Install steering column filler panel.
4. Insert air bag fuse into fuse block.
5. Turn ignition switch to RUN and verify that the air bag warning lamp flashes seven times then turns off.

Passenger Side

1. Turn ignition switch to LOCK and remove key.
2. Insert air bag fuse into fuse block.
3. Turn ignition switch to RUN and verify that the air bag warning lamp flashes seven times then turns off.

when a deployment occur . You need to change both air bag module, change SDM (supplemental deployment module)
need to change the SIR coil Inside column steering and the front discriminating sensor.
Befor installing you need to remove the SIR fuse or disconnect battery
no reset needed

hope it help

Disarming the System

Print

CAUTION The Supplemental Inflatable Restraint (SIR) system must be disarmed before performing many in-vehicle service procedures. Failure to do so may cause accidental deployment of the air bag, resulting in unnecessary SIR system repairs and/or personal injury.

1. Turn the steering wheel so the vehicle's wheels are pointing straight-ahead.
2. Turn the ignition switch to the LOCK position.
3. Remove or disconnect the following:
   
   Ignition key AIR BAG fuse from the instrument panel fuse block Left-hand sound insulator Connector retainer and yellow 2-way connector at the base of the steering column. Right-hand sound insulator, if equipped with passenger side air bags Connector retainer and yellow 2-way connector from the passenger inflator module pigtail, if equipped with passenger side air bags

you have to buy a new multi-function switch. someone with tools and know how has to pull the steering wheel off, replace the switch, and reattach the steering wheel without damaging or deploying the air bag.

used switches are available on eBay, however given the level of difficulty in replacing it i would use a new one. GM dealer can sniff around and find them. and if you google around long enough you can find them too.

Well first disconnect the positive side of the battery. Then I recommend grounding the positive battery cable to the frame or negative side of the battery. (This will insure you have all possible stored voltage removed from your system). Your 95 model has two types of steering wheels and air bags. Model 1 there are four holes in the back of the steering wheel. You simply push a small punch or ice pick in the center to release the airbag from the steering wheel. If you have the later model 1995, there is a slot and you have to push a wire clip that holds the bag to the steering wheel. Once you get the air bag off the wheel, it just unplugs and you remove the steering wheel using a puller. All GM air bag circuits are yellow. They won't deploy without power. Good luck, I hope this helps.

you need to buy new air bags and a new computer for the air bags you will also need to replace the clock spring in the steering wheel, I do not suggest you do this without knowing anything about the air bag system as it can kill you. This one is for a professional, and the older cars have added items that need to be checked like accelerometers and crash sensors on the front of the radiator core support and on each fender, any one of these items could deploy the air bag if defective. and the old ones deploy at 180 miles per hour.

You may need to call several salavage yards, but there should be one out there that will sell you one without the air bag. If your steering wheel isn't damaged, you might be able to disconect the air bag from the steering wheel.

disconnect battery positive and negative to prevent air bag deployment

clockspring is behind steering wheel.

If the computer in the air bag diagnostic monitor detects an open in the air bag indicator circuit and if another system fault exists, then the air bag diagnostic monitor will turn on its internal tone generator (beeper). The beep pattern is five sets of five beeps. The pattern is repeated every 30 minutes while the ignition switch is in the ON position. The five beeps do not indicate a code five or any other code. The air bag indicator circuitry must be repaired before the diagnostic trouble code can be read.
