B0081 on Honda
First Row Center Seatbelt Load Limiter Deployment Control (Subfault)
B0081 on Honda vehicles indicates first row center seatbelt load limiter deployment control (subfault). Au7o has documented this code across 1 Honda model — most commonly on Civic. This is a supplemental restraint (SRS) code relating to the deployment control circuit for the first-row center seatbelt load limiter / pretensioner. The airbag control module monitors this restraint circuit and sets the code when it detects an electrical fault such as an open, short, or out-of-range resistance. Because it involves a crash-protection device, the airbag/SRS warning light typically illuminates and the related restraint may not deploy correctly in a collision. Typical repair costs on Honda range from $150 to $900, depending on the specific model and root cause.
Common Causes of B0081
- •Open or shorted wiring in the load limiter / pretensioner circuit
- •Faulty or already-deployed restraint pretensioner
- •Corroded or loose connector at the seatbelt/restraint device
- •Damaged connector under the seat or in the floor harness
- •Faulty airbag (SRS/SDM) control module
- •Poor ground to the restraint system
- •Wiring damage from seat movement or moisture

- Body Control Module Parasitic Battery Drain2016-2019
Owners of 10th-gen Civics, especially 2017s, report the Body Control Module (BCM) failing to fully power down after the car is shut off, leaving a parasitic current draw that flattens the 12V battery overnight or over a few days. Because the BCM stays partially awake, the drain continues until the battery is depleted, leading to repeated no-starts and premature battery replacements that don't fix the underlying issue.
