Replacing a faulty Airbag Module in a Porsche 986 can be a daunting task. This guide provides a step-by-step approach to replacing the airbag module, saving you a significant amount compared to dealership repairs. This DIY project utilizes a Durametric diagnostic tool and focuses on replacing the entire module.
Identifying a Faulty Airbag Module
A persistent airbag warning light is the primary indicator of a potential issue with the airbag system. Using a diagnostic tool like a Durametric, you can read the specific error code. In this case, a faulty seat belt tensioner triggered the airbag module fault code. While repairing the tensioner or the module’s capacitor is possible, this guide focuses on a complete module replacement using a donor car.
Airbag Module Location and Removal
Safety First: Always disconnect the battery and wait several minutes before working on any airbag system components.
The airbag module in a Porsche 986 is located beneath the stereo head unit, in front of the gear shifter. Accessing the module is straightforward:
- Remove Side Panels: Carefully pop off the side panels around the center console. Apply even pressure to avoid breaking the tabs. No tools are required for this step.
- Locate the Module: Once the panels are removed, the airbag module is visible.
- Remove Safety Bolts: The module is secured by tamper-proof bolts. These can be removed using pliers. Patience is key when working with these bolts. Replace these with standard 10mm nuts upon reinstallation.
Airbag Module Replacement and Reset
- Disconnect and Replace: Unplug the faulty airbag module and connect the replacement module. Ensure the connection is secure.
- Reinstall Module: Bolt the new module in place using standard 10mm nuts.
- Reconnect Battery: After securing the module, reconnect the battery.
- Reset Airbag Light: Use the Durametric tool to reset the airbag warning light. This step is crucial to confirm the successful installation and clear the error codes.
Conclusion
Replacing the airbag module in a Porsche 986 is a manageable DIY project with the right tools and guidance. This guide offers a cost-effective solution compared to expensive dealership quotes. Remember to prioritize safety by disconnecting the battery before working on the airbag system. Utilizing a diagnostic tool like a Durametric ensures accurate diagnosis and successful reset of the airbag system. A successful airbag module replacement restores the safety functionality of your vehicle and extinguishes the warning light.
