Pull the code with an SRS-capable scanner, type it below, and we will tell you in plain English what it points to and whether a module reset can clear it.
Start typing and matching codes appear below. We cover the most common SRS B-codes across GM, Ford, Chrysler, Toyota, Honda, Nissan, and more.
When your SRS (supplemental restraint system) light stays on after an accident, the airbag control module has done its job. It fired the airbags or pretensioners it was told to fire, then it wrote a permanent record of the event into its own memory. That record is what we call crash data, or hard codes. The module locks itself so it will not arm again until that record is cleared. A standard OBD2 scanner cannot erase it, which is why your code reader at the parts store reports the light but cannot turn it off.
There are two very different reasons an SRS code shows up, and they get treated as the same thing all the time:
The module recorded a deployment or a crash-threshold event. The hardware is fine, the memory is just locked. This is cleared by a module reset in our shop. Codes like B0051, B1193, and B1231 are textbook examples.
A sensor, a connector, the clock spring, or the module itself failed its self-test. The part has to be repaired, and the light comes right back on the next start-up until it is. Codes like B1000, B1620, and many circuit faults fall here.
Replace the failed part, then clear the code.
A few codes can go either way depending on the make and what actually happened to the car. That is why we read the code carefully and trace it to the exact circuit or sensor before we say anything. Send us your airbag control module and we test it, tell you whether a reset clears it, and return it factory-ready if it does. Use the lookup above to get a head start, then pick your code below for the full breakdown.
One safety note. A module reset clears stored data. Physical repairs are a separate job: your vehicle has to be mechanically safe and the deployed airbags and belts properly replaced before the system can protect anyone again.
Every manufacturer numbers its codes differently and calls the module something different. Start with your make for the families, the scan tool quirks, and the codes we see most.
Each page covers what the code means, the common causes, whether it is crash data or a hardware fault, and whether our reset clears it. Manufacturer meanings vary, so we note the differences.
