OBD-II fault code

B0060: Driver Seatbelt Tension Sensor (Subfault)

What it means

This code identifies a fault associated with the driver 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 driver seat-belt tension sensor measures belt tension for the restraint control module, which uses the signal as part of its restraint-system decisions. The module monitors the tension-sensor signal and circuit for a fault; the accompanying subfault information identifies the specific condition.

Common causes

Most likely first.

  1. Damaged tension sensor wiring or connector
  2. Faulty seat belt tension sensor
  3. Seat belt retractor or belt mechanism fault
  4. 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

  1. Retrieve the B0060 subfault and freeze-frame data with a restraint-capable scan tool before clearing the code.
  2. Check that the driver's belt extends and retracts smoothly and that the retractor and belt are not visibly damaged or obstructed.
  3. Inspect the driver tension-sensor connector and wiring near the belt mechanism for looseness, corrosion, chafing, or damage.
  4. Compare driver belt-tension data on the scan tool while the belt is slack and then gently drawn, following the vehicle's service guidance.
  5. Test the tension sensor and circuit using the manufacturer's procedure; evaluate the restraint control module only after the sensor and wiring pass.

Common fixes

  • Reconnect or repair damaged driver tension-sensor wiring.
  • Repair corrosion or damaged terminals at the sensor connector.
  • Replace the faulty driver seat-belt tension sensor or specified retractor assembly.
  • Repair or replace the restraint control module only after confirming its power, ground, connections, and sensor input.

Can I keep driving?

The vehicle may be driveable, but the restraint module may not correctly assess the driver's belt tension, which can affect how the system responds in a crash. Wear the belt correctly, avoid using a belt with a sticking or damaged retractor, and arrange prompt diagnosis.

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.
