What causes the airbag warning light to illuminate on the dashboard?
1 Answers
The reasons for the airbag warning light illuminating on the dashboard: 1. Foreign objects around the airbag sensor wiring harness, especially metal debris causing a short circuit, leading to false warnings. 2. The warning light may illuminate due to erroneous data reported by the car's ECU sensor. 3. If the warning light comes on without reason, it is likely caused by the vehicle being parked in a humid environment for a long time or moisture in the wiring connectors during car washing, resulting in a short circuit. 4. A fault in the airbag itself, mostly caused by loose connectors. However, if the USB also fails, the fault in the airbag itself can be largely ruled out.
