Code B0071 2016 GMC Sierra Description
The B0071 diagnostic trouble code (DTC) for a 2016 GMC Sierra relates to the Passenger Seat Belt Tension Sensor Circuit. This code indicates that there is a malfunction in the circuit responsible for monitoring the tension in the passenger seat belt. The seat belt tension sensor is a crucial safety component that ensures the proper functioning of the vehicle's supplemental restraint system (SRS) or airbag system. When the sensor detects that the passenger's seat belt is not properly tensioned, it sends a signal to the SRS control module to deploy the airbag in the event of a collision.
Common Causes of B0071 2016 GMC Sierra
- Damaged wiring or connectors in the seat belt tension sensor circuit.
- Faulty seat belt tension sensor.
- Loose or disconnected connections in the circuit.
- Corrosion or moisture damage in the sensor circuit.
- Impact or physical damage to the seat belt tension sensor.
Symptoms of B0071 2016 GMC Sierra
- Airbag warning light illuminated on the dashboard.
- Inability to properly tension the passenger seat belt.
- Faulty deployment or non-deployment of the passenger airbag.
- Diagnostic trouble code B0071 stored in the vehicle's computer system.
How to Fix B0071 2016 GMC Sierra

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
