The B0100-49 Fiat Ducato fault code will cause the constant illumination of the airbag warning light, commonly an issue that is suffered by 2011 to 2019 models. If this B0100-49 Fiat Ducato fault code is present, it is a sure indication that the TRW D219 airbag ECU is faulty. A failing airbag ECU may result in the airbags failing to deploy in emergency situations, which will severely impact the safety of the vehicle.
In addition to a persistent airbag warning light, and the presence of B0100, or B0100-49 Fiat Ducato fault codes being found with diagnostics, it is possible to encounter an error with diagnostics being unable to establish communications with the airbag ECU, generating no fault code. This is, in fact, another symptom of failure, and should be considered when diagnosing an airbag ECU fault.
Remember, this control module has a green plug and is only fitted to post-2011 Fiat Ducato vehicles. If the airbag ECU you require a repair of is from a pre-2011 Fiat Ducato, has a black plug and a B1001 code stored, this is a different control module and you should click here.
