B00D5 - Passenger airbag deactivation warning light fault airbag control unit fault

What does error code B00D5 mean in the airbag control unit?

Error code B00D5 indicates a fault in the passenger airbag deactivation warning light on DS Automobiles. The affected part is therefore the display through which the airbag system shows the status of the passenger airbag deactivation, and the airbag control unit stores the fault in the fault memory and switches on the airbag warning light.

The passenger airbag is part of the restraint system (SRS), which is controlled by the airbag control unit. The fault is therefore reported at this display.

The message therefore relates to the passenger airbag deactivation. The fault remains stored in the control unit until it has been resolved.

How do you recognise error code B00D5?

Error code B00D5 shows up as a permanently lit airbag warning light, and the code is stored in the fault memory of the airbag control unit. The entry cannot be permanently erased, and it is read out with a diagnostic tool that retrieves the fault message from the airbag control unit as soon as it is connected.

The finding therefore shows on the airbag warning light and in the fault memory. As long as the entry is there, the fault is not considered resolved.

What causes error code B00D5?

The possible causes are a plug or a cable leading to the warning light, the warning light itself as a component, and the airbag control unit. Which of these applies cannot be said with certainty without checking the connections and components, which is why the check comes first.

• a plug on the warning light or on its supply cable
• damaged cables to the warning light
• the warning light itself, if it is faulty as a component
• the airbag control unit itself, if the cause is not external

Whether a plug, a cable or the control unit is affected is shown by the check at a specialist workshop.

In which vehicles does error code B00D5 occur?

Error code B00D5 is known on DS Automobiles, for example on the models DS 3 I Crossback, DS 4 II, DS 7 I Crossback and DS 9 I. So far, the code is only known for the DS Automobiles brand, to which all the model series mentioned belong.

On other vehicles the meaning of this code may differ, and the list is not complete. What matters, therefore, is the specific vehicle on which the code occurs, that is, make, model and model series.

How is error code B00D5 resolved?

Error code B00D5 is resolved by first reading out the fault memory with a diagnostic tool, so that the cause can be narrowed down. Plugs, cables and the warning light are only checked at a specialist workshop, and the control unit is only sent in if it is itself the cause.

Work on the airbag system should be left to qualified specialists.

If the cause lies in the control unit, first disconnect the battery and then remove the control unit. Then create a repair order online and send the unit to Airbag24.

Checking, repairing and testing usually take 3–4 working days. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
