how do I fix the SRS system issue in my Ford F-150 13th Generation (2015-2020)

Solution

1. Preparation

• Gather necessary tools: OBD-II scanner, multimeter, socket set, torque wrench, and safety glasses.
• Disconnect the vehicle’s battery to prevent accidental airbag deployment during repairs.

2. Retrieve and Analyze Codes

• Connect the OBD-II scanner to the vehicle’s diagnostic port.
• Turn on the ignition without starting the engine.
• Read and document any trouble codes related to the SRS system.
• Clear the codes and see if they reappear after a short drive.

3. Inspect Airbag Module and Wiring

• Remove the dashboard panel covering the airbag module.
• Visually inspect the module for damage, corrosion, or loose connections.
• Use a multimeter to test continuity in the wiring harness leading to the airbag module.
• Repair or replace any damaged wiring or connectors as necessary.

4. Check Seatbelts and Pretensioners

• Remove the seat covers if necessary to access seatbelt pretensioner connectors.
• Inspect the connectors for dirt, corrosion, or damage.
• Ensure the seatbelt assembly is functioning properly by checking retraction and lock mechanisms.

5. Reassemble and Test

• Reconnect all components securely, ensuring no loose wires or connectors.
• Reinstall the dashboard panel and any seat covers removed during inspection.
• Reconnect the battery and turn on the ignition to check if the SRS light remains off.
• Conduct a test drive to confirm the warning light does not reappear.
