Description
Steering wheel airbag, driver’s airbag for Peugeot 407
High-quality replacement steering wheel airbag designed for Peugeot 407. This driver airbag corresponds to part numbers 96445891ZD and 4112HA and is intended for vehicles equipped with the original SRS system. The module contains the inflator and airbag cushion integrated into the steering wheel center and restores the vehicle’s passive safety function after deployment or when the original unit develops an electrical fault. Ideal for professional mechanics and experienced DIY enthusiasts who search by OE code (96445891ZD, 4112HA).
Technical Information
- Manufacturer: Peugeot / Stellantis
- Model: Peugeot 407
- Product Codes: 96445891ZD
- Additional Numbers: 4112HA
Installation Recommendations
Working with SRS components requires care. Follow these general steps and always consult the vehicle’s repair manual for model-specific instructions:
- Disconnect the negative battery terminal and wait at least 10 minutes to allow residual charge in the SRS system to dissipate.
- Remove the steering wheel trim and access screws or bolts that retain the airbag module. Use the correct tools and avoid prying on plastic tabs.
- Carefully unplug the airbag electrical connectors (note the locking clips) and remove the old module. Inspect wiring and connector pins for corrosion or damage.
- Fit the replacement airbag, connect the electrical plugs securely, and reinstall retaining fasteners. Follow the vehicle manufacturer torque specifications for steering wheel and airbag fasteners.
- Reconnect the battery and clear SRS fault codes with a compatible diagnostic tool. Verify the SRS warning light extinguishes after the vehicle’s self-check.
Why This Part Fails Most Often
Steering wheel airbags are not consumable items but can fail or require replacement for several reasons:
- Previous Deployment: The most common cause is prior airbag deployment in a collision. Deployed modules must be replaced.
- Electrical Faults: Damaged connectors, corroded pins or broken wiring in the clock spring (spiral cable) can cause SRS errors and prevent deployment.
- Mechanical Damage: Impact to the steering wheel, improper repairs, or forceful removal/installation can damage the module or its connectors.
- Environmental Factors: Moisture ingress or long-term corrosion of contacts may lead to electrical faults and SRS warning lights.
Practical Notes for Mechanics and DIYers
Always inspect the clock spring and steering wheel wiring when replacing the airbag—many SRS faults attributed to the airbag module originate in the spiral cable. Use an OBD SRS-capable scanner to read and clear codes. Replace the module if it shows damage, deployment residue, or persistent fault codes that do not clear after repairing wiring or connectors.
Compatible with Peugeot 407 vehicles using OE references 96445891ZD and 4112HA. Fitment depends on the vehicle’s original equipment; check part numbers on the original unit before installation.
