B1330 means the driver front impact sensor is reporting the wrong identification to the SRSCM, and the usual reason is that the wrong part is fitted. The module knows which sensor belongs there and it is hearing from a different one.
Hyundai impact sensors identify themselves to the module when the system powers up. The SRSCM compares that identification against what the vehicle configuration says should be present. A mismatch gets stored as B1330 and the system stays disabled, because a module cannot calibrate crash decisions around a sensor it does not recognize.
This is a parts problem far more often than an electrical one. Sensors that look identical across models and years can carry different identification, and a unit pulled from a donor car or ordered by appearance rather than by application will set this code the first time the key goes on.
B1330 describes a mismatch between parts rather than a resistance out of range, which is why it lands in the hardware group. Crash data is a different record entirely, written permanently into the module after a deployment and beyond the reach of a scan tool. Fitting the correct sensor is what settles this code.
Restoring the module does not make a wrong sensor into the right one. Our mail-in service clears locked crash data and puts the SRSCM back to factory state, which is the fix after a deployment. With B1330 the answer is the correct part. If a used module was installed along with the used sensor, both need to match the vehicle before the system will arm.
Hyundai uses B1330 for the driver side front sensor identification mismatch. It reads on Hyundai scan tools alongside the other B13 front sensor codes, and telling them apart saves you from replacing a good part.
Compare the installed sensor against the correct application for the exact vehicle before doing anything else, including checking that the left and right sensors did not get swapped during installation. Find out whether the sensor or the module came out of another car, since a donor part on either end produces this code. Fitting the genuine OEM sensor for that vehicle is what clears it, and we can help you identify the right one. Related codes: B1329, B1333, B2204-00.
