Description
This Steering Wheel Airbag is specified for Peugeot 406 vehicles and references part numbers 96500907ZL and 4112GT. It is intended as a direct-fit replacement module for the driver side airbag in compatible Peugeot 406 steering wheels. The description and fitment target professional mechanics and experienced DIY enthusiasts who routinely work on PSA platform vehicles.
Key Features
– Direct-fit driver airbag module for compatible Peugeot 406 steering wheels.
– Supplied to match the referenced part numbers 96500907ZL and 4112GT for quick identification.
– Designed to interface with the vehicle electrical connector and steering-clock spring used on the cited models.
Why This Part Matters
The steering wheel airbag is a primary occupant restraint device. It deploys in frontal impacts to reduce the risk of head and chest injuries. After a deployment or when the airbag system signals a fault (airbag warning light), the airbag module must be replaced by a correct part that matches the vehicle’s part number and connector type.
When To Replace
- After deployment in a collision.
- If diagnostics show an airbag circuit fault that traces to the airbag module.
- If the module or its connector has been damaged or contaminated (for example by water or corrosion).
Common Causes Of Failure
- Activation during a crash (single-use device).
- Electrical faults such as damaged wiring or connector corrosion.
- Clock spring wear or damage causing intermittent contact to the airbag circuit; this commonly triggers the airbag warning lamp.
Installation Overview
Only perform installation if you are competent and equipped to work on supplementary restraint systems. General safe steps include:
- Disconnect the negative battery terminal and wait at least 10 minutes to allow system capacitors to discharge.
- Follow vehicle manufacturer procedures to remove the steering wheel trim or horn pad to access the airbag module retaining fasteners.
- Carefully disconnect airbag electrical connectors; avoid pulling on wiring. Do not place the airbag face down on hard surfaces.
- Install the replacement module, reconnect connectors, ensure the clock spring is correctly aligned, and torque steering fasteners to the manufacturer’s specification.
- Reconnect the battery and confirm the airbag warning light goes out after the vehicle self-check; if the light remains on, perform diagnostic trouble code reading.
Compatibility And Fitment Note
Confirm that the part numbers 96500907ZL or 4112GT match the airbag currently fitted to your Peugeot 406. Airbag modules can look similar but vary by connector, steering wheel trim, and vehicle option codes. Always verify fitment by cross-referencing the vehicle VIN, steering wheel type, or existing part number before ordering.
