Symptoms
- Warning light or symbol related to the affected system
- Comfort or safety function impaired
Common causes
- 01Seat harness connector under passenger seat damagedMost likely
- 02Side airbag squib circuit openPossible
- 03SRS control module faultLess likely
Can I drive with B0024?
The car drives, but it is a safety risk.
With an airbag or restraint fault stored, one or more airbags or pretensioners may not deploy in a crash. Get it diagnosed soon and do not ignore a lit airbag light.
Why we rate it urgent
- An airbag or seat-belt pretensioner may not work in a crash
- Does not normally turn on the check engine light
Severity is our rule-based rating from the code’s flags in OBDex and the system it affects, not an inspection of your car. If the check engine light is flashing, or you notice overheating, low oil pressure, or brake or steering problems, stop driving and get help.
How to diagnose B0024
- 1
Confirm the code and save freeze-frame data
Read the codes with an OBD-II scan tool and note every code, not just B0024. Save the freeze-frame data (speed, load, temperature when the fault set) before clearing anything; it tells you when the fault happens.
- 2
Fix other faults first
If other codes are stored, start with power-supply, sensor-circuit and communication codes. They can cause this code as a side effect.
- 3
Check live data
Watch the related sensor and actuator readings in live data (Right side airbag module, SRS control module, SRS wiring) and compare them with expected values in the service information for your vehicle.
- 4
Test the likely causes in order
Start with the most likely cause and work down: Seat harness connector under passenger seat damaged; side airbag squib circuit open; SRS control module fault. Test before replacing parts.
- 5
Check for recalls and service bulletins
Look up recalls for your exact vehicle with its VIN, and ask a dealer about technical service bulletins (TSBs). Manufacturers sometimes issue software updates or extended warranties for known faults.
- 6
Clear the code and verify the repair
After the repair, clear the code and drive the car under the conditions in the freeze-frame data to confirm it does not return.

What causes B0024?
The most common causes, from most to least likely: Seat harness connector under passenger seat damaged; Side airbag squib circuit open; SRS control module fault. Test before replacing parts, because several causes can set the same code.
How much does it cost to fix B0024?
Typical labor is about $65–$375 at an assumed $125/hour shop rate, plus parts. That is an estimate, not a quote: labor times and rates vary by vehicle and region, and diagnosis may be billed separately.

DIY difficulty is hard. Most owners leave this to a shop because it needs involved testing or specialist tools. Always confirm the cause before buying parts.
Will B0024 clear itself?
If the fault was intermittent, the warning may go off once the computer stops seeing it, but the code stays in memory. Fix the cause; clearing the code alone doesn’t repair anything.
