What is a Daihatsu Atrai S700 airbag control unit?
The Daihatsu Atrai S700 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It monitors sensors, stores crash data, and ensures the proper functioning of all airbag modules in the vehicle. Our repair service restores this critical function.
This microcontroller-based device processes real-time data from acceleration and impact sensors. It is compatible with the 12-volt vehicle electrical system and is often connected to other vehicle systems via the CAN bus.
The unit performs continuous self-diagnosis and reports faults via the OBD interface. It coordinates the deployment of driver, passenger, and side airbags, as well as the seat belt pretensioners.
The robust control unit is typically located in the dashboard or under the center console. It is connected to all relevant sensors and actuators via multi-pin connectors.
Why is the Daihatsu Atrai S700 airbag control unit defective?
A Daihatsu Atrai S700 airbag control unit often malfunctions due to aging electronic components, voltage spikes, or crash data stored after an accident. Such a blockage requires a targeted Daihatsu Atrai S700 airbag control unit repair to restore the system's full functionality and safety.
Because electronic components are subject to natural aging, their performance can deteriorate over time. This can lead to malfunctions or complete system failure.
An accident, even if the airbags aren't deployed, can still block the control unit. The crash data must be professionally erased and the system reinitialized to ensure safe continued driving.
Common error codes for Daihatsu Atrai S700 airbag control unit repair
During Daihatsu Atrai S700 airbag control unit repairs, specific error codes are often read out, indicating internal problems. These generic B-codes signal malfunctions within the control unit itself, such as internal memory errors or communication problems, which require precise diagnosis and correction.
- B1000 → Control unit communication error → Internal system error or wiring problem.
- B1100 → Internal memory error in the airbag control unit → Defective EEPROM or processor.
- B1200 → Airbag control unit self-test failed → Hardware or software defect in the control unit.
- B1300 → Voltage error in the airbag control unit → Unstable power supply or internal controller defect.
- B1400 → Software error in the airbag control unit → Corrupted firmware or programming error.
- B1500 → EEPROM error in the airbag control unit → Faulty data memory for vehicle data.
- B1600 → Faulty communication between airbag control unit and ABS/ESP control unit → CAN bus malfunction or internal communication error.
- B1700 → Internal bus error in the airbag control unit → Problem on the internal data line of the control unit.
- B1800 → Watchdog error in the airbag control unit → Monitoring circuit detects system standstill.
- B1900 → Airbag control unit initialization error → System startup or restart error.
- B2000 → Internal hardware error in the airbag control unit → Defective electronic components within the control unit.
- B2100 → Memory overflow in the airbag control unit → Too much data or program error.
- B2200 → Internal firmware integrity error → System software corruption.
- B2300 → Airbag control unit voltage drop → Temporary voltage loss or battery problem.
What part numbers are available for the Daihatsu Atrai S700 airbag control unit repair?
Exact OEM part numbers for the Daihatsu Atrai S700 airbag control unit are not publicly available. Reliable identification requires access to official Daihatsu parts catalogs, TecDoc databases, or direct information from original equipment manufacturers such as Autoliv, often in combination with the vehicle identification number (VIN).
Since part numbers vary greatly depending on the vehicle's equipment and model year, the serial number of the defective control unit is crucial. This is the only way to ensure compatibility for a successful Daihatsu Atrai S700 airbag control unit repair.
Without direct access to specialized workshop information systems, 100% verified part number determination is impossible. This underscores the need for professional diagnostics and consultation prior to repair.
