Occupant Classification System Performance
The system is detecting performance issues with the occupant classification system.
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 car’s computer notices that the sensors checking if a passenger is in the seat or their weight aren’t working right.
What the computer is actually seeing
The control module expects to see consistent resistance readings from the seat sensors typically within 0.5 - 5 ohms, depending on weight, but detects out-of-range values.
What a healthy reading looks like
Resistance readings from the occupant sensors should fall between 0.5 - 5 ohms for normal operation.
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. Check the wiring and connectors under the passenger seat for damage or loose connections. Repair as necessary.
- 22. Inspect the seat cushion for signs of wear or damage. Replace if necessary.
- 33. Measure the resistance of the occupant sensors using a multimeter. If values are outside 0.5 - 5 ohms, replace the sensor or seat assembly as needed.
- 44. Clear the code and perform a seat occupancy test to see if the code returns.
Common causes
- Faulty occupant sensors
- Damaged wiring or connectors
- Seat cushion wear or damage
- Malfunctioning control module

Frequently asked questions
Is it safe to drive with this code active?
Yes, the vehicle is safe to drive, but be aware that the airbag system may not work properly in an accident because it won't detect the passenger correctly.
Will this code come back after clearing it?
If the underlying issue isn’t fixed, the code will likely return after clearing and may trigger a warning light again.
Why does it pair with other codes?
These codes are related to the same system; issues in the occupant classification can often trigger multiple related faults.
