Seat Belt Sensor Circuit Failure
The seat belt sensor circuit is not functioning properly.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The seat belt sensor that detects if you're buckled up is not sending the right signal to the car's computer. This can happen due to wiring issues or a faulty sensor.
What the computer is actually seeing
The seat computer expects a specific resistance value when the seat belt is buckled. If it detects an open circuit or short circuit, it triggers the B2298 code.
What a healthy reading looks like
Resistance should be within the 0 to 5 ohms range when buckled. If it's open, it reads as infinite resistance (>20,000 ohms).
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the seat belt sensor wiring and connectors for damage or corrosion. If damaged, repair or replace.
- 22. Use a multimeter to measure the resistance at the seat belt connector. If not within 0-5 ohms when buckled, the sensor is likely faulty.
- 33. Ensure the seat control module is receiving proper voltage (typically 12V). If not, check power and ground to the module.
Common causes
- Faulty seatbelt sensor
- Damaged wiring or connectors
- Faulty Seat Control Module

Frequently asked questions
Is it safe to drive with this code?
Yes, but it's important to address it soon to ensure seat belt system functions correctly in an accident.
Will this code come back after clearing it?
If the underlying issue isn't fixed, yes, the code will likely return.
Why does this code often appear with B2297?
B2297 and B2298 are both related to the seat belt sensor system, indicating different faults in the same circuit.
