# Frontal Supplemental Inflatable Restraint (SIR) Switch Kits

Subject: | Frontal Supplemental Inflatable Restraints (SIR) Switch Kits -- Parts and Service Procedures -- Due to new regulation, this bulletin supersedes 97-T-33 which should be discarded. Retailers Should On Longer Use the Information Contained In 97-T-33. Instead, Use the Information Included With This Bulletin.

Models: | 1992-1998 Saturn vehicles

### Purpose:

Never consider installing an airbag on off switch unless the following conditions are met:

1. The customer presents a letter from the National Highway Traffic Safety Administration (NHTSA) Authorizing the Installation of the Air Bag ON-OFF Switch.

Important: Make sure to get a photocopy of the customer's letter from the NHTSA and retain the photocopy in the CSO VIN jacket, stapled to the CSO Hardcopy.

2. The retailer gives the customer a copy of the Notice to GM/Saturn Owners About Air Bag ON-OFF Switches. Refer to Retail Support Team Bulletin 97-SC-07.
3. The customer still wants the Air Bag ON-OFF Switch installed.

This bulletin provides service information for the installation and removal of air bag ON-OFF switches to turn OFF and ON frontal supplemental inflatable restraints (SIR) (Air bags), along with switch and system diagnosis.

The National Highway Traffic Safety Administration (NHTSA) has given approval and direction for deactivating Frontal Supplemental Inflatable Restraints (SIR) systems in special situations. Within this approval, the method to deactivate the Frontal (SIR) modules (air bags) includes a switch(es) to turn the air bag(s) OFF and ON, and display to indicate SIR system deactivation status.

The air bag ON-OFF switch installation kit contains the necessary components (air bag ON-OFF switch, brackets, attaching hardware, display light, applique sheet for switch and light, tie straps and instruction sheets) for system operation. Each kit also contains an Owner's Handbook insert describing system operation for review by the owner.

The cost of the air bag ON-OFF switch kit and labor to install the switch kits are the responsibility of the customer. Suggested labor times for kit installation are included at the end of this bulletin.

Important: In rare instances, the installation of an air bag ON-OFF switch(es) may turn ON the vehicles AIR BAG warning light. This condition may exist due to the additional resistance of the switch harness when added to the SIR system. For further assistance, call the Saturn Technical Assistance Center at 1-800-828-2112, prompt 1.

The standard SIR System diagnosis can be made by disconnecting the air bag ON-OFF switch from the SIR wiring harness and following the directions for SIR system diagnosis found in the appropriate year SIR Service Manual.

A description of each of the installation kits major components is as follows:

### Air Bag ON-OFF Switches:

Each air bag ON-OFF switch kit contains material for one air bag (driver or passenger). The air bag ON-OFF switches are key operated. When the air bag ON-OFF switch is in the OFF position, the air bag will remain OFF until the air bag ON-OFF switch is turned to the ON position. Turning the air bag ON-OFF switch to the ON position will allow the air bag to function.

Caution: To prevent personal injury, air bag ON-OFF switches must not be placed on any instrument panel surface directly in front of the driver's or passenger's leg or knee area.

The recommended location for air bag ON-OF switches on Saturn vehicles is in the instrument panel (glovebox) compartment assembly.

### Display Light:

Each air bag ON-OFF switch requires a display light to indicate the ON or OFF status of the air bag. Each display light includes a harness to be connected to the air bag ON-OFF switch.

Caution: To prevent personal injury, air bag display lights must not be placed on any instrument panel surface directly in front of the driver's or passenger's leg or knee area.

The recommended location fro the display lights is at the center of the roof headliner (refer to the location illustration in this bulletin and the instruction sheet).

### Wiring Connections:

The air bag ON-OFF switch will be connected in series with the yellow 2-way air bag connector. The air bag ON-OFF switch also requires ignition circuit, body ground, and display light connections.

Diagnostics for the switch and display light are included with this bulletin. Refer to the appropriate model year SIR service manual for SIR system diagnosis.

### Parts Information

Order the appropriate installation kit(s) (driver's, passenger's or both) from SSPO. Parts information containing the air bag ON OFF switch kit part numbers is located at the end of this bulletin.

### Warranty Information:

Air bag, ON-OFF switch kits and installation are NOT considered a warranty repair. Parts and labor charges are the responsibility of the customer.

### Service Precautions:

Caution: Switches and telltale lights must not be mounted on any instrument panel surface directly in front of the driver or passenger seating areas. Instrument panel surfaces that may come in contact with knees or head must be kept free of switches and telltale lights.

Caution: As a system Pre-check, perform the following to verify the system operation. Staying well away from both air bags, turn the ignition switch to the run position. Verify that the air bag warning lamp flashes 7 times and then stays OFF. If the air bag warning lamp does not operate as described, perform the SIR Diagnostic System Check found in the SIR Service Manual.

The inflatable restraint sensing and diagnostic module or the diagnostic energy reserve module (Depending on the model year of the vehicle) Maintains a reserve energy supply. When the vehicle power is insufficient to cause deployment of the air bags, the reserve energy supply provides the deployment power. Deployment power is available for as long as 10 minutes after disconnecting the vehicle power by any of the following methods.

• | You turn OFF the ignition switch.

• | You remove the fuse that provides power to the inflatable restraint sensing and diagnostic module or diagnostic energy reserve module.

• | You disconnect the vehicle battery from the vehicle electrical system.

### Service Procedure for Installation of Air Bag ON-OFF Switches

### Wire Splicing

With the wiring used in the Saturn vehicles, it is recommended that approved Delphi Packard Electric Crimp and Seal Splice Sleeves, or equivalent, be used.

1. Remove the insulation from both ends, recommended strip length is 9.5 mm (3/8 in). Caution must be used to prevent cutting the wire strands. Locate the new splice a minimum of 40 mm (1½ in) from an outlet or other splice.
2. Determine the proper sleeve for the gage of wire. Position the stripped ends in the sleeve until the wires hit stop.

Important: When using the salmon splice sleeve with 0.35 (22gage) wire, remove 19 mm (3/4 in) of insulation. Bend the stripped portion in half to double the thickness of the wire going into the splice sleeve. Twist the stripped, doubled wire and insert it into the splice sleeve.

3. Hand crimp the sleeve using the approved crimping tool. Gently tug on the wires to ensure they are secure before applying heat to them.

Caution: Do not use a match or open flame to apply heat to a splice sleeve.

4. Apply heat using Ultratorch™ or equivalent, heating the splice sleeve to 175°C (347°F). Heat until the glue flows around the edges of the splice sleeve.
5. Check for continuity in the wire.
