What fault is reported when the airbag control module is broken?

When the airbag control module is broken, it will report an airbag fault. The relevant introduction about airbag faults is as follows: Dashboard self-check for airbag faults: After entering the vehicle and during the short period of ignition, the dashboard will perform an automatic check. After the automatic check is completed, the airbag light will automatically turn off, which usually takes about 5 seconds and is a normal phenomenon. If the airbag light remains on for a long time after the self-check is completed, it can be determined that there is indeed a fault. False airbag faults: If the battery is low on power, it can also cause the airbag light to turn on. Additionally, the airbag system may feedback a signal indicating low pressure in a certain airbag, generating a fault code. In this case, simply clearing this fault code will resolve the issue.
When the airbag control module fails, common symptoms include the airbag warning light on the dashboard staying illuminated or flashing, which typically appears when starting the vehicle. Fault codes will be stored in the vehicle's onboard system, such as internal circuit errors or communication fault codes read via OBD diagnostics. This may prevent the airbags from deploying properly during a collision, significantly compromising driving safety. I recommend immediately connecting a diagnostic tool to confirm the fault codes, then seeking professional technicians to replace the control unit to avoid delays in addressing the issue. Regular maintenance should include avoiding water exposure or battery-related damage, and inspecting related systems during routine servicing can help prevent potential risks. Remember, airbags are crucial passive safety equipment, and improper maintenance can increase the risk of injury in accidents.
When my airbag control module failed last time, the airbag warning light on the dashboard kept staying on. The repair shop scanned it with a diagnostic computer and found a fault code indicating internal damage to the module, requiring the entire unit to be replaced. The repair took some time, but it fixed the warning light issue and restored the airbag functionality. More importantly, this incident highlighted that if the control unit fails, the airbags might not deploy in an emergency, significantly increasing the risk of injury. Now I always glance at the dashboard before driving to ensure all warning lights are functioning normally. Experience has taught me not to underestimate these small alerts—timely attention can prevent major troubles.
