Mazda 6 Airbag Light Due to Under-Seat Wiring Connector Fault

This is the most common cause for intermittent SRS lights. Confirm this by checking for a high-resistance fault code specifically attributed to seat-side airbag circuits. Physically verify the condition of the yellow wiring harness connectors located beneath the front seats. A fault is confirmed if the light state changes when the wiring is gently manipulated, or if the connection shows visible signs of oxidation, looseness, or terminal fretting.
