Code B0022 2015 GMC Sierra Description
The B0022 code for a 2015 GMC Sierra refers to an issue with the passenger seat belt retractor pretensioner deployment loop. In modern vehicles, seat belts are equipped with pretensioners that retract the seat belt in the event of a crash to minimize the forward movement of the occupant and reduce the risk of injury. The deployment loop is a crucial component of this system, as it triggers the pretensioner to activate in the event of a collision.
Common Causes of B0022 2015 GMC Sierra
- Faulty wiring: Damaged or frayed wiring in the seat belt pretensioner system can disrupt the flow of electrical signals and trigger the B0022 code.
- Malfunctioning sensor: A defective sensor that monitors the deployment loop's status can lead to erroneous readings and the activation of the B0022 code.
- Blown fuse: A blown fuse in the seat belt pretensioner system can prevent the deployment loop from functioning correctly, triggering the B0022 code.
- Damaged deployment loop: Physical damage to the deployment loop itself, such as corrosion or breakage, can cause the system to malfunction and trigger the B0022 code.
Symptoms of B0022 2015 GMC Sierra
- Warning light on the dashboard: The most common symptom associated with the B0022 code is the illumination of the airbag or seat belt warning light on the dashboard.
- Inoperative seat belt pretensioner: The passenger seat belt pretensioner may fail to deploy or retract properly in the event of a collision.
- Audible warning chime: Some vehicles may emit an audible warning chime to alert the driver to a problem with the seat belt pretensioner system.
- Erratic behavior of the seat belt: The seat belt may exhibit unusual behavior, such as not retracting smoothly or getting stuck in the buckle.

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.
