Seat belt warning light stays on or flashes after buckle operation
Persistent seat belt chime or no chime when buckle is engaged
SRS/airbag warning lamp may illuminate (if the restraint system monitors the sensor)
Driver occupant classification or belt-status incorrect on instrument cluster
Diagnostic trouble code B0060 stored in SRS/body control module

Read and record DTCs and freeze frame data from airbag/body control modules
Visually inspect driver seat belt buckle, sensor housing and mating connectors for corrosion, damage or water ingress
Check fuse(s) and power supply(s) for the restraint/SRS or body control module circuits
Attempt buckle/unbuckle while monitoring live data for buckle/tension sensor status
Wiggle test wiring along seat rails while watching live data for intermittent changes
Verify ground(s) at seat and module are clean, tight and corrosion-free

Expected supply/reference: typically 5 V reference (verify factory service data)
Signal output: normally a variable voltage or resistance proportional to tension (typical 0.5–4.5 V or specific resistance range — consult OEM spec)
Resistance of sensor when unbuckled vs buckled: consult service data (example expected ranges vary by manufacturer)
CAN/serial: restraint module can advertise buckle/tension status periodically (e.g., 10–100 Hz) — verify comm present

Connect a diagnostic scan tool and note all stored DTCs, freeze frame, and live data for driver belt/tension sensor. 2) Clear codes and attempt to reproduce B0060 by buckling/unbuckling and seat movement; record when code returns. 3) Visually inspect the buckle sensor, harness, and connectors for damage, corrosion, bent pins or water intrusion; repair as needed. 4) With ignition ON, verify reference supply (typically 5 V) and ground at the sensor connector using a DVOM; compare to OEM values. 5) Probe the sensor signal wire while buckling/unbuckling; verify signal changes smoothly and stays within expected voltage/resistance range from service data. 6) Perform wiggle tests of wiring along seat rails and connector while monitoring live data to detect intermittent faults. 7) If no wiring fault found, disconnect sensor and measure its resistance per OEM procedure; replace sensor if out of spec. 8) Check related module communications (CAN/LIN) and ensure the module reporting the fault is responding; check for other module faults (U-codes) that could affect detection. 9) After repairs, clear codes and perform functional test (drive/seat movement cycles) to confirm fault does not return.
