• Restart the vehicle and take a short test drive if the airbag light flashes continuously. The purpose of this is to help the vehicle restart an energy cycle. Before starting, check whether the wiring under the seat is loose, the plug is not damaged.
• Check that the seat belt system is loose or unfastened, or improperly fastened in the occupied position.
• Check if the passenger seat airbag switch is off. This situation only occurs in some vehicles fitted with an on/off button for the airbag in the passenger seat.
• Check the sensor in the passenger seat. If the weight placed on the chair is too large (usually objects), the sensor system mistakenly thinks the person is sitting and lights up. To solve this situation one is to remove the object from the passenger seat and fasten the seat belt for the object.

• Check the clock spring. If broken or damaged, proceed to replace.

Step 3: If after trying everything, the sensor light still shows an error, bring it to the center, auto repair garage to perform the test, give the most optimal and fastest solution. Avoid the case where it takes a long time or does not completely solve the error, causing inconvenience and unsafety during use.
