Resetting the airbag module in your Honda Civic can be done at home with a few simple tools and careful attention to timing. This guide provides a detailed walkthrough of the process, helping you clear the SRS (Supplemental Restraint System) light after addressing the underlying issue that triggered it.
Understanding the Honda Civic Airbag System
The SRS light illuminates when the airbag system detects a fault. This could be due to a deployed airbag, a disconnected sensor, or a problem with the module itself. Before attempting to reset the module, it’s crucial to diagnose and fix the root cause of the SRS light. Simply resetting the module without addressing the underlying problem won’t resolve the issue and could be dangerous. This reset procedure will only clear the stored fault codes.
Materials Needed for Honda Civic Airbag Module Reset
To reset your Honda Civic airbag module, you’ll need:
- SCS Service Connector: This tool bridges the gap in the MES connector. You can purchase a pre-made connector or create one using a speaker harness from an older Honda, available at electronics stores. Cut and loop the wires together to form the connector. A paperclip can be used as a temporary alternative but requires precise and rapid connection and disconnection.
Locating the MES Connector in Your Honda Civic
The MES (Memory Erase Signal) connector is typically located within the fuse box under the dashboard on the driver’s side. It’s a yellow, two-wired connector. Consult your Honda Civic’s owner’s manual for the precise location if you have difficulty finding it.
Honda Civic Airbag Module Reset Procedure
Follow these steps carefully, paying close attention to the timing:
-
Preparation: Turn the ignition off. Disconnect the yellow MES connector from the fuse box and pull it down for easier access. Connect your SCS service connector to the two terminals of the MES connector.
-
Ignition On: Turn the ignition key to the “On” position (do not start the engine). The SRS light will illuminate for approximately 6 seconds and then turn off.
-
First Disconnect: Within 4 seconds of the SRS light turning off, quickly disconnect the SCS service connector from the MES connector. The SRS light will illuminate again.
-
Reconnect: Within 4 seconds of the SRS light turning back on, reconnect the SCS service connector to the MES connector. The SRS light will turn off.
-
Second Disconnect: Within 4 seconds of the SRS light turning off, disconnect the SCS service connector from the MES connector. The SRS light will blink twice, indicating that the memory has been successfully erased.
-
Confirmation: Turn the ignition off and wait for at least 10 seconds. Start the vehicle as normal. The SRS light should illuminate briefly and then turn off, confirming a successful reset.
Troubleshooting
If the reset procedure doesn’t work on the first attempt, double-check your connections and repeat the steps, ensuring precise timing. If the SRS light persists, the original problem might not be resolved and requires further diagnosis by a qualified technician. Remember, safety is paramount when working with airbag systems. If you are unsure about any step, consult a professional mechanic. This procedure applies to many Honda Civics but always refer to your specific model’s service manual for the most accurate information.
