B0081 on Cadillac
First Row Center Seatbelt Load Limiter Deployment Control (Subfault)
B0081 on Cadillac vehicles indicates first row center seatbelt load limiter deployment control (subfault). Au7o has documented this code across 1 Cadillac model — most commonly on XTS. 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 Cadillac range from $300 to $1,500, 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

Cadillac XTS(1 issue)
- Passenger Presence System Fault / Passenger Airbag Light On2013-2019
The front passenger seat contains a Passenger Presence System (occupant-classification sensor/module and wiring harness) that tells the airbag controller whether to enable the passenger airbag. On the XTS the sensor mat, the under-seat connector, and the wiring harness are prone to faults, illuminating the SRS/'Service Air Bag' warning and often leaving the PASSENGER AIRBAG OFF indicator stuck on (or incorrectly on with an adult seated). Because a fault can disable passenger airbag deployment, this is a genuine safety concern.
