How The Airbag Works
The driver airbag contains an inflator assembly and a folded airbag cushion. In the event of a qualifying impact the SRS control unit triggers the igniters that inflate the cushion within milliseconds, helping to reduce forward movement and impact forces on the driver. This module is a central element of the vehicle restraint system and works together with seatbelts and pretensioners.
How To Replace
Replacement of the steering wheel airbag should be performed by a trained technician or an experienced DIYer who follows SRS safety rules. Typical replacement steps:
- Disconnect The Battery And Wait The Manufacturer-Specified Interval Before Starting Work (At Least 10 Minutes If Manufacturer Interval Is Unknown).
- Set The Steering Wheel Straight To Preserve Clock Spring Position.
- Remove Trim Screws Or Fasteners From The Back Of The Steering Wheel To Release The Airbag Module.
- Carefully Disconnect Electrical Connectors, Noting Retention Clips And Connector Orientation.
- Replace The Airbag Module And Reconnect All Plugs Securely. Inspect The Clock Spring (Spiral Cable) For Damage; Replace If Necessary.
- Reinstall Fasteners To Specified Torque, Reconnect The Battery, And Clear SRS Fault Codes With A Diagnostic Tool.
Installation Recommendations
- Always Follow Manufacturer Safety Procedures And Torque Specifications.
- Use Proper Diagnostic Equipment To Check And Clear SRS Fault Codes After Installation.
- Inspect The Clock Spring And Steering Column Wiring For Wear Or Damage When Servicing The Airbag.
- Do Not Attempt To Modify Or Test The Inflator Manually; Handle Modules With Care And Store With The Deployment Surface Facing Up.
Why This Part Fails Most Often
- Deployment During A Collision: Airbags Are Single-Use Components And Must Be Replaced After Deployment.
- Clock Spring Or Connector Failure: Intermittent Or Open Circuits In The Spiral Cable Or Connectors Can Cause SRS Faults.
- Electrical Damage Or Corrosion: Moisture Ingress Or Damaged Wiring May Prevent Proper Igniter Activation.
- Previous Incorrect Installation: Improper Handling Or Incorrect Torqueing During Past Repairs Can Lead To Malfunction.
