Step 1: Perform visual inspection of the driver's seatbelt retractor assembly and tension sensor for physical damage, water intrusion, or signs of previous deployment. Check for proper sensor mounting and cable routing.

Step 2: Disconnect the seatbelt tension sensor connector and inspect both male and female terminals for corrosion, bent pins, or moisture. Clean contacts with electrical contact cleaner and dielectric grease if corrosion present.

Step 3: Using a digital multimeter, measure resistance across the tension sensor terminals (typically 2-5 ohms depending on manufacturer). Compare readings to factory specifications. Check for infinite resistance indicating open circuit or zero resistance indicating short.

Step 4: With ignition off, inspect wiring harness from sensor to BCM for chafing, pinch points near seat tracks, and proper securing. Perform continuity test on each wire and check for shorts to ground or power.

Step 5: Clear the code and perform a test drive with multiple seatbelt buckling/unbuckling cycles. Monitor live data for tension sensor voltage/signal using scan tool to verify stable readings during normal operation.

Step 6: If all wiring and sensor tests pass, perform BCM voltage supply test (typically 5V reference) to tension sensor. If supply voltage is unstable or absent, BCM replacement or reprogramming may be required.
