Crash Reset or Incident Data Storage Reset SRS
RESET Airbag Control Unit Nissan Qashqai

This service is dedicated to the reconditioning of the airbag control unit after an accident.

How to recognize if the control unit needs a reset:

• The first clear symptom is the airbag warning light being on.
• During diagnosis, you may find errors such as "crash," "internal fault," or "impact data stored."
• The control unit usually does not allow fault deletion, even after sensor replacement.
• In some vehicles, if the accident was minor, resetting can be performed with a good generic diagnostic tool.

Fault codes indicating the need for a reset:

• B107F 49: "Control unit needs replacement due to collision."

Description of the process and precautions:

The airbag control unit reset after an accident involves clearing the recorded errors and reactivating the airbag system. After an accident, airbag sensors may register events and generate error codes indicating a possible issue with the system. These codes are stored in the airbag control unit.

The reset should be performed by a specialized technician, restoring the airbag system to its normal operational state.

It’s important to note that the airbag control unit reset should only be performed by qualified professionals, as working with vehicle safety systems requires specific expertise to ensure the system functions correctly when needed. Additionally, the reset should not be viewed as a way to avoid repairing or replacing damaged components after an accident; a full evaluation of the airbag system should be conducted, and any damaged components should be repaired or replaced as necessary.
