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.

When searching for a Fiat Ducato airbag ECU repair, you’ll usually get the standard advice of buying a new replacement ECU, directly from the manufacturer. However, this is not the most cost-efficient route. Due to the need to reprogram the ECU from scratch, not only will a new unit be expensive from the start, it will also carry extra labour costs, and longer wait times, not to mention the short one year manufacturer warranty that will be attached.

Instead, we propose having your control module comprehensively rebuild. We go a step further than standard repair service by completing reworking your Fiat Ducato airbag ECU with higher-than-OEM-standard components.

As above, my Airbag module was repaired by CrashData last August - only to fail again last week (7 months and 1700 miles later). However, I don't see my unit on your list - part number 013751 100 80.Do you rebuild this item? I am very impressed that you can offer a lifetime warranty and would be prepared to pay for the rebuild option if you can offer it on this part. Please let me know. I have a 2015 Hymer Motorhome on a Ducato chassis. Many thanks Brian
