What is a Toyota Proace Verso airbag control unit?
The Toyota Proace Verso airbag control unit is the digital brain of the passive safety system, coordinating the precise deployment of all airbags and seatbelt pretensioners in the event of a collision. It continuously monitors sensors, stores relevant crash data, and is essential for the safety of the Toyota Proace Verso's occupants.
It processes signals from various crash and acceleration sensors to assess the need for deployment in milliseconds.
The compact, vibration- and temperature-resistant unit is usually installed centrally in the center console or under the dashboard of the vehicle.
Why is the Toyota Proace Verso airbag control unit defective?
A Toyota Proace Verso airbag control unit can fail, often as a result of an accident where crash data is permanently stored, or due to moisture and electronic malfunctions that cause failure. Proper repair or replacement is essential to restoring vehicle safety, especially if the airbag warning light remains permanently illuminated.
After an accident, these control units store crash data, which can block their further function and make repairs necessary.
Moisture ingress, short circuits or age-related material fatigue can also lead to failure of the internal electronics.
Sometimes software errors or an inconsistent power supply can cause the airbag control unit to break.
Common error codes for Toyota Proace Verso airbag control unit repair
When diagnosing a faulty Toyota Proace Verso airbag control unit, specific error codes will appear that indicate problems within the control unit itself or its direct monitoring functions. These codes are crucial for establishing an accurate diagnosis for the necessary repair and ruling out other components.
- B1000 → Control unit communication error → A malfunction in the internal communication of the airbag control unit itself, often an indication of a defect.
- B1651 → Manual Cut off Switch Trouble → A problem with the manual cut off switch for the passenger airbag, which is monitored directly by the control module.
- B1660 → Passenger Airbag ON/OFF Indicator Circuit Malfunction → A malfunction in the indicator circuit for the passenger airbag status, also controlled by the airbag control module.
These error codes must be read using special diagnostic tools before a Toyota Proace Verso airbag control unit repair can be carried out.

It is strongly recommended to check the part number against the vehicle's chassis number before ordering a spare part to ensure an exact fit.
Procedure for a Toyota Proace Verso airbag control unit repair
Repairing a Toyota Proace Verso airbag control unit requires specialized knowledge and precise steps, from accurate diagnosis to safe recommissioning. This process is complex and should only be performed by qualified workshops to restore the safety system to full functionality and prevent failure.
First, a comprehensive diagnosis is carried out using specialized software to read all existing error codes and determine the exact cause of the defect.
If the control unit only contains crash data, a professional deletion and reset of the module can be the solution, thus avoiding expensive new purchases.
In case of irreparable damage, the airbag control unit must be replaced, followed by coding to the specific vehicle model.
After the repair, the system must be finally tested to ensure that all airbags and sensors are functioning correctly and that there are no other faults.
A professional workshop ensures that the repair of the Toyota Proace Verso airbag control unit meets the highest safety standards.
