B0022 -

While the exact definition can vary slightly by manufacturer, for most vehicles (Chevrolet, GMC, Cadillac, Buick), B0022 specifically identifies a fault in the Right Front (Passenger) Seat Belt Retractor Pretensioner Deployment Loop [13, 21].

The most frequent culprit is a poor electrical connection. A common issue involves the yellow connectors located under the passenger seat or behind the B-pillar trim [16, 18].

Some modern vehicles may display a "Service Airbag" or "Seat Belt Fault" message on the driver information center [2]. While the exact definition can vary slightly by

The most obvious sign is the illuminated "SRS" or "Airbag" light on the dashboard [2, 3].

In many cases, the computer will disable the entire airbag system as a precaution when this code is active [6, 7]. Typical Causes Some modern vehicles may display a "Service Airbag"

GM vehicles often suffer from loose or broken Connector Position Assurance (CPA) clips—small plastic tabs that ensure a secure connection. Replacing these is a common low-cost fix [6, 15].

A seat belt pretensioner is a pyrotechnic device that uses a small explosive charge to instantly tighten the seat belt during a collision [6, 18]. The , or airbag computer, monitors this circuit’s electrical resistance. If the resistance falls outside the normal range (typically 1.1 to 3.9 ohms ), the SDM triggers B0022 and illuminates the airbag warning light [2, 18]. Common Symptoms Typical Causes GM vehicles often suffer from loose

Never use a standard multimeter to test the resistance of an airbag or pretensioner. The small electrical current from the meter can trigger the explosive charge and cause the component to deploy [4, 6, 18]. Is this code appearing on a specific vehicle model , or
