Examples of SRS airbag diagnostic codes include Code 12 for low battery voltage, Code 13 for grounded or shorted airbag circuit and Code 14 for a short in the primary crash sensor. Additional examples include Code 21 for airbag mounting diagnostic and Code 22 for a sensor output short.
The supplemental restraint system is responsible for monitoring and deploying a vehicle's seat belt and airbag crash safety features. SRS dash warning lights indicate a problem in the system, and a diagnostic scan of the ECU transmits blinking two-digit SRS codes that further indicate specific problems. Automotive technicians are responsible for diagnosing, inspecting and resetting vehicle SRS codes.
