What is a Daihatsu Altis A200 airbag control unit?
The Daihatsu Altis A200 airbag control unit is your vehicle's central safety unit, continuously monitoring sensor data. It precisely deploys the airbags and seatbelt pretensioners in the event of an impact, providing comprehensive occupant protection. It also stores important crash data to ensure vehicle safety after an accident.
This electronic module is crucial for the passive safety of the Daihatsu Altis A200. It evaluates information from various crash sensors.
The proper functioning of the control unit is essential to ensure that all restraint systems are activated in an emergency.
Why is the Daihatsu Altis A200 airbag control unit defective?
A Daihatsu Altis A200 airbag control unit often fails because it irreversibly stores crash data after an accident, requiring professional repair. Internal components can also fail due to overvoltage, water damage, or age-related wear and tear. This usually results in the airbag warning light remaining permanently illuminated and the safety systems no longer functioning fully.
After an impact, the crash data is stored in memory, which prevents the system from being reset without special deletion.
A control unit failure can also be caused by electrical problems or internal hardware errors, which requires immediate diagnosis in the workshop.
Common error codes for Daihatsu Altis A200 airbag control unit repair
When repairing the Daihatsu Altis A200 airbag control unit, error code B1342 is particularly common and relevant, as it specifically indicates crash data stored in the control unit. This code indicates that the module cannot be reset after an accident without professionally erasing the crash data or repairing the control unit.
This error code is related directly to the control unit and not to peripheral sensors.
Clearing the B1342 error is necessary after repairing the control unit to deactivate the airbag warning light.
- Code B1342 → Meaning: "Crash data stored" → Cause: A previous accident has left permanent data in the control unit.
What part numbers are available for the Daihatsu Altis A200 airbag control unit repair?
For Daihatsu Altis A200 airbag control unit repairs, exact OEM part numbers cannot be verified from the available information, as these require specific data from manufacturer catalogs. To determine the correct part number, a comparison with official Daihatsu sources, TecDoc databases, or reading the defective control unit itself is essential.
The exact part numbers can vary greatly depending on the year of manufacture and equipment variant of the Daihatsu Altis A200.
It is recommended to use the vehicle's vehicle identification number (VIN) to accurately identify the required control unit before having it repaired.
Functionality and technical specifications of the Daihatsu Altis A200 airbag control unit
The Daihatsu Altis A200 airbag control unit repair focuses on restoring a component that monitors sensor data in real time and sends trigger signals to airbags and seatbelt pretensioners in the event of an accident. It features an OBD-II interface for diagnostics and is designed for 12V vehicle electrical system operation to ensure comprehensive vehicle safety.
The control unit continuously receives signals from crash sensors that measure acceleration and pressure.
Within a few milliseconds of an impact, the trigger pulses are sent to the pyrotechnic units.
The communication interface is typically via CAN bus or LIN bus in order to be integrated into the vehicle network.
The housing material is made of high-quality plastic with EMC protection, which prevents malfunctions caused by electromagnetic interference.
Installation position and compatibility for Daihatsu Altis A200 airbag control unit repair
The Daihatsu Altis A200 airbag control unit is usually installed centrally in the vehicle, often under the center tunnel or the passenger seat, to ensure optimal sensor detection. It is specifically designed for the Daihatsu Altis A200 model series (model years approximately 2010-2015). However, exact compatibility should always be checked using the vehicle identification number before repairing.
This central position protects the control unit from damage and enables reliable signal processing.
The control unit is compatible with vehicles that have standard front and side airbags and seat belt pretensioners.
After installing the repaired module, software adaptation or programming in a specialist workshop may be necessary to ensure full functionality.
Why is it useful to repair the Daihatsu Altis A200 airbag control unit?
Repairing your Daihatsu Altis A200 airbag control unit is a cost-effective and sustainable alternative to purchasing a new one. A professionally repaired module will once again meet all original functional parameters, ensure full safety, and avoid unnecessary electronic waste. This saves costs and conserves valuable resources.
A repaired control unit ensures full compatibility with existing airbag sensors and trigger units.
It meets the strict safety standards of vehicle manufacturers and is a reliable option to fix the error in the system.
