What does checking SRS mean?

Checking SRS means checking the airbag. The specific introduction of SRS is as follows: 1. This fault does not have a major impact on the driving of the car, but when the vehicle encounters an accident, the airbag will not open and will not play a passive protective role. 2. After receiving the signal, it is compared with the originally stored signal. If the conditions for airbag deployment are met, the drive circuit sends a start signal to the gas generator in the airbag assembly. After receiving the signal, the gas generator ignites the gas generating agent, which enters the airbag, causing the airbag to break through the liner and deploy rapidly in a very short time, effectively protecting the human head and chest.
Last week, the SRS warning light suddenly came on in my car, so I took it to a repair shop for a check. It turns out that SRS stands for the Supplemental Restraint System (airbag system), and this warning on the dashboard indicates a detected fault in the system. The mechanic connected a diagnostic scanner to the OBD port to check the trouble codes and mentioned that it could be due to a loose wiring harness under the front seats' impact sensors or a faulty airbag control module. He emphasized that I should never attempt to unplug connectors myself, as the airbag circuit contains detonators, and improper handling could cause the airbags to deploy unexpectedly and cause injury. In the end, it was discovered that the wiring harness connector under the passenger seat had been pressed when I installed the floor mats last time. Reconnecting it tightly solved the issue. This kind of check-up really shouldn't be delayed, as airbags are life-saving equipment.
