Code B0060 indicates a fault in the driver seatbelt tension sensor circuit. This sensor is a small potentiometer typically mounted on the seatbelt retractor or buckle assembly. Its job is to measure the tension in the driver's seatbelt and send this information to the vehicle's SRS (airbag) control module or body control module. This data helps the restraint system determine the driver's seating position and belt usage, allowing it to tailor airbag deployment force during a collision.
The most noticeable symptom is the seatbelt warning light staying on or displaying a 'belt not fastened' message even when you are properly buckled in. The seatbelt itself will continue to function normally for everyday use — it will still lock during hard braking and restrain you in a collision. However, the airbag system may not be able to optimize its deployment force, and in some vehicles, this fault can partially disable the SRS system.
This is one of the more DIY-accessible SRS-related repairs. The tension sensor is relatively inexpensive and is often integrated into the seatbelt retractor or buckle assembly. In many vehicles, it can be accessed by removing the lower B-pillar trim and the seat side panel. However, because it interfaces with the SRS system, the battery should always be disconnected and the SRS capacitor allowed to discharge before beginning work. If you're not comfortable working around airbag components, have a professional handle the repair.
Severity
Symptoms
- •Seatbelt warning light stays on even when the belt is fastened
- •Seatbelt reminder chime does not sound or sounds incorrectly
- •Instrument cluster displays a false 'belt not fastened' message
- •Airbag warning light may also illuminate due to shared SRS circuit
- •Seatbelt warning behavior may be intermittent or inconsistent
Likely Causes
The seatbelt tension sensor is a potentiometer mounted on the retractor or buckle that measures belt tension and reports to the Passenger Presence System. Internal wire breakage, corrosion, or a worn potentiometer element can produce out-of-range voltage signals.
The sensor wiring runs under the driver seat and along the B-pillar, areas prone to physical damage from seat adjustment mechanisms, items stored under the seat, and moisture intrusion.
The buckle switch and tension sensor often share the same connector assembly. A corroded or damaged buckle switch can create electrical interference that causes the tension sensor to report incorrect readings.
If the BCM or SRS module loses communication with the tension sensor due to a CAN bus fault or module issue, it cannot read the sensor data and sets this code as a default.
