B000213 airbag control unit fault

What does error code B000213 mean?

Error code B000213 indicates an internal fault in the airbag control unit (SRS – Supplemental Restraint System). This defect prevents proper monitoring and control of the restraint systems, meaning that airbags and seatbelt pretensioners may fail to deploy in the event of a crash. For safety reasons, the system is deactivated.

In vehicle diagnostics, B‑codes (body codes) fall under the category of body electronics. An error such as B000213 signals that the control unit’s self‑diagnostic has detected a problem within its own hardware or internal data processing.

Unlike faults related to external components like sensors or wiring, this issue originates directly within the module itself. The internal logic can no longer ensure proper functionality, so the entire safety system is switched to a passive, safe state.

What symptoms are associated with B000213?

The primary and most obvious symptom of error code B000213 is the persistent illumination of the airbag warning light (SRS warning lamp) on the instrument cluster. Typically, the error cannot be cleared and reappears immediately or shortly thereafter. No additional external malfunctions in the vehicle are expected.

The airbag warning light remains continuously illuminated after starting the vehicle and does not extinguish as usual following the system check. This is a clear indication of a permanent, safety‑critical fault in the restraint system.

In the workshop, communication with the airbag control unit via a diagnostic tool is often difficult or impossible. The error cannot be permanently cleared because it stems from a hardware or internal data fault that cannot be resolved by a simple reset.

What causes B000213?

The main cause of error code B000213 is an internal hardware or data fault directly within the airbag control unit. This can result from aging electronic components, voltage spikes in the vehicle’s electrical system, or corrupted memory data. External factors such as faulty sensors are rarely responsible for this specific code.

Electronic components like microprocessors, memory chips (EEPROM), or capacitors undergo an aging process. Over time, thermal stress and vibrations can lead to microscopic damage that ultimately triggers an internal fault.

Unstable power supplies—such as those caused by a weak battery or faulty jump-starts—can also generate voltage spikes. These spikes may damage the sensitive electronics inside the airbag control unit, leading to a permanent failure.

Which vehicles are affected by B000213?

Error code B000213 primarily occurs in certain models from American manufacturers such as Chrysler and Dodge. Various generations and model series equipped with a specific generation of airbag control units are impacted. At Airbag24, we have successfully repaired this fault in numerous vehicles of these brands.

At Airbag24, we service airbag control units exhibiting error B000213 across several models, including:

Chrysler: Newport, 2nd and 3rd generations.

Dodge: Viper (3rd gen), Nitro (1st gen), Dart (1st, 2nd, 3rd, and 4th gen), Daytona (1st gen, 2nd gen, G-series), Shadow (1st gen, P-series 1986–1994), Monaco (2nd and 3rd gen), and Omni (2nd gen).

How does repair work at Airbag24?

Repair of error B000213 at Airbag24 focuses on restoring the removed airbag control unit. Upon receipt, our technicians analyze the hardware at the component level, rectify the internal fault, and restore the original functionality. The unit is then thoroughly tested and ready for immediate installation.

The process begins with the professional removal of the control unit from the vehicle. After submission to Airbag24, a detailed incoming inspection is performed to confirm error B000213 and rule out any additional potential defects.

This is followed by actual component‑level repair, where defective parts such as processors or memory chips are identified and expertly replaced. The control unit’s internal data is reviewed and, if necessary, restored to factory settings.

Following successful restoration, the control unit undergoes comprehensive functional testing on a specialized test bench. The repaired unit is returned as a plug‑and‑play solution and becomes operational immediately upon reinstallation. We provide 2 years' statutory liability for defects on all repairs.
