Step 1: Verify the “Hot” Condition

• Reproduce the fault by parking the vehicle in direct sunlight for 2-3 hours, then driving with the air conditioning off for 10 minutes.
• Use an infrared thermometer to measure the driver’s seat buckle temperature. If it exceeds 55°C and the code appears, heat is the trigger.

• Check for corrosion, bent pins, or melted plastic (common in Thai high-humidity areas).
• Perform a resistance test across the buckle switch: Should be <1 ohm when buckled, infinite when unbuckled. If resistance jumps when you wiggle the wire while heating with a hair dryer, the buckle is faulty.

Step 2: Clear Codes and Cool Down

Clear the code. Run the A/C at max for 30 minutes. Restart the engine. If the code returns immediately, the sensor is permanently damaged. If the code stays away, monitor for recurrence. Reproduce the fault by parking the vehicle in
