B1483 on Hyundai
Driver Airbag Resistance Circuit Short to Ground (2nd stage)
B1483 on Hyundai vehicles indicates driver airbag resistance circuit short to ground (2nd stage). Au7o has documented this code across 1 Hyundai model — most commonly on Accent. The Airbag Control Unit (ACU/SRSCM) measures the resistance of each squib firing loop. B1483 sets when the second-stage (dual-stage) driver front airbag inflator circuit measures a short to ground. Hyundai lists this code as one of a defined set that qualifies a vehicle for ACU replacement, indicating the fault is diagnosed as internal to the control unit rather than in the airbag or wiring, and the remedy in the bulletin is to replace the ACU. Typical repair costs on Hyundai range from $250 to $2,400, depending on the specific model and root cause.
Common Causes of B1483
- •Internal fault in the Airbag Control Unit (ACU/SRSCM) — the remedy Hyundai specifies in TSB 24-BE-014H is ACU replacement
- •Short to ground in the driver airbag second-stage squib circuit wiring
- •Damaged clock spring / steering column wiring harness
- •Corroded or damaged driver airbag inflator connector
B1483 on Hyundai by Model
Hyundai Accent(1 issue)
- Passenger Occupant Classification Seat Sensor Mat Failure (Airbag / PASSENGER AIRBAG OFF Light)2006-2017
The occupant classification sensor mat built into the front passenger seat cushion fails internally - the printed pressure-sensing traces crack with repeated loading. The car then either lights the SRS/airbag warning lamp with an OCS fault stored, or leaves the PASSENGER AIRBAG OFF indicator lit with an adult sitting in the seat, meaning the passenger airbag will not deploy in a crash. It affects MC (2006-2011) Accents heavily and continues on later cars, and it is well documented across Hyundai/Kia models generally. The financial sting is that Hyundai does not sell the mat separately - the fix is the entire lower seat cushion assembly, and forum owners have posted dealer quotes in the $1,200-$2,400 range for what is a failed sensor pad.
