B0026 on GMC
GM frontal airbag deployment loop fault
Severity: Inspect soon
The airbag light means the system found a fault, and owner's manuals say to have it checked promptly because the airbags may not work as designed; this code concerns a frontal airbag deployment circuit.
This page covers only what differs on GMC. For what B0026 means, the ranked causes and the test order, see the B0026 guide.
