Fiat 500 Airbag Light On - B1041 Driver Pretensioner Open Circuit

Question

My 2015 Fiat 500 just popped the SRS/Airbag warning light on the dash after I slid the driver seat back to clean under it. I scanned it with an Autel unit and got code B1041. I really need to get this cleared before my inspection next week.

The issue was high resistance in the yellow under-seat connector. After disconnecting the battery, I unclipped the connector and found one of the female pins had backed out slightly. I cleaned the pins with contact cleaner, carefully tightened the terminal tension with a pick, and secured the harness with a zip tie to prevent it from moving when the seat slides. The code B1041 cleared instantly and the airbag light has stayed off for over 500 miles. Total cost was $0 for the fix.

Use a multimeter to check for continuity on the harness side, but never bridge the pins on the airbag side itself. It's common for the terminals inside the yellow connector under the seat to lose 'spring' tension, causing a high resistance or open circuit fault.

This code specifically refers to the circuit for the driver's side seat belt buckle or the pillar-mounted pretensioner depending on the exact sub-variant of the code. Start by disconnecting the battery for 30 minutes before probing any yellow SRS connectors to avoid accidental deployment.

Check the wiring harness that runs along the floor under the seat. These cars are known for the harness getting pinched in the seat track mechanism if the plastic clips break off.
