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

Technically, the vehicle will drive normally. However, If the airbag warning light is on, the passenger seat belt pretensioner—and often the entire airbag system —may not deploy during a crash, significantly increasing the risk of serious injury [6, 8, 16]. How to Fix It The most obvious sign is the illuminated "SRS"

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 How to Fix It Never use a standard

Pinched, frayed, or broken wires in the B-pillar or under-seat area can disrupt the circuit [19, 21]. Using a "load tool" or specialized resistor to

Using a "load tool" or specialized resistor to simulate a working pretensioner can help determine if the problem is in the wiring or the pretensioner itself [4, 18].

Code is a safety-critical diagnostic trouble code (DTC) that indicates a fault within your vehicle's Supplemental Restraint System (SRS) —commonly referred to as the airbag system [2, 16]. This code typically points to a malfunction in the deployment loop for a specific safety component, often the passenger seat belt pretensioner [2, 18]. What is Code B0022?
