What is a Daihatsu Taft LA900 airbag control unit?
The Daihatsu Taft LA900 airbag control unit is the central safety unit in your vehicle, activating all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors the safety system sensors, stores important crash data, and ensures the proper functioning of all airbag modules. A timely and professional Daihatsu Taft LA900 airbag control unit repair is essential for vehicle occupants.
This module, also known as the SRS control unit, is the brains of the passive safety system. It receives signals from impact sensors and decides in milliseconds whether to activate the necessary restraint systems.
Why is the Daihatsu Taft LA900 airbag control unit defective?
A Daihatsu Taft LA900 airbag control unit often fails because it irreversibly stores crash data after an accident, necessitating reprogramming or replacement. Internal electronic errors, overvoltage damage, or communication problems in the vehicle's electrical system can also lead to failure and paralyze the entire airbag function.
If the airbag control unit has internal errors, the airbag warning light on the dashboard usually illuminates. This signals a critical condition of the SRS system.
A faulty control unit can significantly compromise vehicle safety, as it no longer functions reliably in an emergency. Immediate diagnosis and repair is therefore strongly recommended.
Common error codes for Daihatsu Taft LA900 airbag control unit repair
During Daihatsu Taft LA900 airbag control unit repairs, specific error codes may occur that indicate internal problems with the control unit or stored crash data. These codes are crucial for a precise diagnosis and differentiate control unit failures from other SRS component problems.
- B1000 → Control unit communication error → The control unit cannot communicate with other systems or has internal hardware problems.
- B1015 → Faulty Airbag Control Unit → An internal defect or malfunction of the control unit itself has been detected.
- B107E → Airbag module related error → There is a general error within the airbag module, often control unit specific.
- B1139 → Error within the SRS system → A comprehensive error in the entire SRS system that can be traced back to the control module.
- B1342 → Crash data stored (not erasable) → After an accident, irrevocable crash data is stored in the control unit, which requires a reset.
- B207F → SRS Control Module Error → A generic safety restraint system control module error was detected, which often indicates a failure.
What part numbers are available for the Daihatsu Taft LA900 airbag control unit repair?
For Daihatsu Taft LA900 airbag control unit repairs, several authentic OEM part numbers are relevant, both from Daihatsu itself and from renowned suppliers such as Bosch and Continental. Ensuring the correct part number is crucial for the compatibility and safety of the replacement part.

Continental also manufactures control units listed under the number **5WK43705** for compatible Daihatsu Taft LA900 models. Compatibility has been verified and confirmed in Continental and TecDoc databases.
Functionality and specifications of the Daihatsu Taft LA900 airbag control unit
The Daihatsu Taft LA900 airbag control unit continuously monitors all airbag system sensors and seatbelt buckles to ensure safe and targeted deployment of the restraint systems within milliseconds in the event of a collision. This module is the heart of the vehicle's passive safety and essential for any Daihatsu Taft LA900 airbag control unit repair.
It is specifically designed for the Daihatsu Taft LA900 (from approximately 2020 onwards) and supports up to six airbags as standard. The unit is capable of storing crash data, which is essential for accident analysis and subsequent diagnosis.
The connection to the vehicle's electrical system is via CAN bus, enabling rapid diagnostics and control commands. The control unit operates at 12 V and features integrated overvoltage protection.
The airbag control unit is typically installed in the driver's footwell under the dashboard or in the center console. It is protected from vibrations and moisture by special brackets and is connected to the sensors and the vehicle electrical system via multi-pin connectors.
After installation or a successful Daihatsu Taft LA900 airbag control unit repair, calibration of the control unit is required. This ensures that all safety systems are optimally coordinated and function flawlessly in an emergency.
