What is a Daihatsu Rocky A200 airbag control unit?
The Daihatsu Rocky A200 airbag control unit is the central electronic unit that monitors all occupant restraint systems, such as airbags and seatbelt pretensioners, and precisely triggers them in the event of a collision. It continuously collects crash data and ensures the proper functioning of the entire passive safety system in your vehicle.
This SRS control unit is specifically designed for the Daihatsu Rocky A200, a vehicle based on the DNGA platform since November 2019. It ensures the proper functioning of all connected sensors and airbag modules.
The microcontroller-based control system stores important information in EEPROM memory, including crash data and error codes, to enable detailed diagnostics.
Why is the Daihatsu Rocky A200 airbag control unit defective?
The Daihatsu Rocky A200 airbag control unit often fails because it permanently stores crash data after an accident, preventing it from being deployed again. Internal hardware errors, voltage spikes in the vehicle electrical system, or software corruption can also lead to the unit failing and necessitate repair.
After a collision, the airbag control unit stores irreversible crash data, which activates the airbag warning light and disables functionality. This type of disablement requires a professional reset of the control unit to restore its usability.
Other causes of a defect can be electronic problems that make it difficult to read error codes or completely disable the control unit. In such cases, a professional diagnosis and, if necessary, repair of the Daihatsu Rocky A200 airbag control unit is essential.
Common error codes for Daihatsu Rocky A200 airbag control unit repair
No specific manufacturer-specific trouble codes are publicly documented for the Daihatsu Rocky A200 airbag control unit (part numbers 89170-B1380 and R7F701A223). However, the general trouble code B1342 "Crash Data Stored" is frequently encountered, which requires reprogramming the control unit after a crash to reactivate the airbag systems.
Professional diagnostic tools such as the CGDI CG100X or MD Flasher are capable of reading and erasing generic and manufacturer-specific error codes, even if the detailed meanings are not always publicly available.
If the airbag warning light in your Daihatsu Rocky A200 is illuminated, this could indicate a variety of problems, ranging from faulty sensors to the control unit itself. A professional diagnostics at a workshop is always the first step toward a successful repair.
What part numbers are available for the Daihatsu Rocky A200 airbag control unit repair?
For the repair of the Daihatsu Rocky A200 airbag control unit, the original Daihatsu OEM part number 89170-B1380 and the supplier part number R7F701A223 (presumably Bosch/RH850) are primarily relevant. These two numbers identify the correct control unit for your vehicle, ensuring full compatibility and functionality after the repair.
Part number 89170-B1380 is the official Daihatsu OEM number, directly verified for the Rocky A200 airbag control unit. It is crucial for selecting the correct replacement or repair module.
The number R7F701A223 is a corresponding OEM part number from a supplier that is also used for this control unit and accurately describes the hardware component. When purchasing or repairing the Daihatsu Rocky A200 airbag control unit, these numbers should always be checked.
