B0028: Driver Side Airbag Deployment Loop Resistance High
Can you still drive? You can drive, but the driver airbag may not deploy reliably. Have the system inspected soon.
What Does B0028 Mean?
Code B0028 indicates that the resistance in the driver-side airbag deployment loop is higher than the expected range. High resistance in the airbag circuit can prevent the inflator from firing reliably. This is often caused by a deteriorating clockspring or corroded connections in the steering column.
Need to read your codes?
An OBD-II scanner lets you read and clear diagnostic trouble codes from your vehicle's computer. Most scanners work with any car made after 1996.

Frequently Asked Questions
What does high resistance in the airbag loop mean?
It means the electrical connection to the airbag has too much resistance, which can prevent the airbag from firing properly during a crash.
Why does the airbag light come on when I turn the steering wheel?
This is a classic symptom of a failing clockspring. The coiled cable inside is wearing out and losing connection as the wheel rotates.
