What it means
This code identifies a fault associated with the passenger seat belt tension sensor. The restraint control module sets it when it detects a problem with this sensor; the specific fault is identified by accompanying subfault information.
How it works
The passenger seat-belt tension sensor reports how much force the belt is applying, and the restraint control module uses that information when managing occupant restraints. B0061 flags a fault associated with this sensor; the accompanying subfault information identifies the specific detected condition.
Common causes
Most likely first.
- Damaged tension sensor wiring or connector
- Faulty seat belt tension sensor
- Seat belt retractor or belt mechanism fault
- Restraint control module fault
Symptoms
- Airbag warning light on
- Seat belt tension may be misreported
- Seat belt warning may stay on
How to diagnose it
- Read the restraint module's full code and subfault details, plus freeze-frame data if available, to identify the condition recorded for the passenger tension sensor.
- Check the passenger belt for twisting, jamming, or abnormal retraction, since a mechanical belt problem can affect the reported tension.
- Inspect the tension sensor and its wiring and connectors for damage, corrosion, loose connections, or signs of a previous seat repair.
- Use scan-tool data to see whether the passenger belt tension reading changes plausibly as the belt is pulled and released.
- Test the sensor circuit and sensor against the manufacturer's diagnostic procedure, then assess the restraint control module only if the wiring and sensor pass.
Common fixes
- Repair damaged or loose passenger tension-sensor wiring or connector.
- Correct a jammed, twisted, or damaged passenger belt or retractor mechanism.
- Replace a confirmed faulty passenger seat-belt tension sensor.
- Repair or replace the restraint control module only after circuit and sensor checks support it.
Can I keep driving?
The vehicle may remain driveable, but the airbag warning means passenger restraint operation may be impaired. Avoid carrying a passenger until the fault is diagnosed and repaired.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
