What is a Daihatsu Terios J200 airbag control unit?
The Daihatsu Terios J200 airbag control unit is the vehicle's central safety unit, which precisely activates all occupant restraint systems, including airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors impact sensors, stores relevant crash data, and ensures the proper functioning of the entire safety system.
This electronic control unit (ECU) is essential for safety in the Daihatsu Terios J200 (model years 2006 to 2018). It processes signals from various sensors to trigger protective systems as quickly as possible in the event of a collision.
A professional Daihatsu Terios J200 airbag control unit repair is crucial for restoring full functionality after an accident or malfunction. It communicates with other vehicle systems via CAN bus and can be diagnosed via the OBD-II interface.
Why is the Daihatsu Terios J200 airbag control unit defective?
A Daihatsu Terios J200 airbag control unit often fails because it stores irreversible crash data after an impact, preventing further operation. Internal memory errors such as EEPROM problems or software corruption can also lead to failure, causing the airbag warning light to remain permanently illuminated.
Typical causes of failure include internal errors in the EEPROM memory or a hardware defect that renders the control unit unusable. Such internal malfunctions can impair the safety function and require repair or replacement.
After an airbag deployment, the module stores crash data, making reuse impossible without a reset. A specialized Daihatsu Terios J200 airbag control unit repair shop can erase this data and restore the module to working order, providing a cost-effective alternative to purchasing a new one.
A power surge or moisture can also damage the airbag control unit. The module's continuous self-diagnosis detects such errors and reports a system failure.
Common error codes for Daihatsu Terios J200 airbag control unit repair
During Daihatsu Terios J200 airbag control unit repairs, specific B-codes often occur. These signal internal problems with the module and indicate memory or communication errors. These error codes require a precise diagnosis and are often the reason for a necessary airbag control unit repair.
- B1000 → Control unit communication error → Problems with data transmission with other vehicle components or internally.
- B1001 → Internal memory error in the airbag control unit → Damage or corruption of data in the internal memory of the module.
- B1005 → EEPROM read/write error in the control unit → Defects in the EEPROM memory area that is responsible for permanent data such as crash data.
- B1010 → Airbag ECU voltage sensor error → Abnormalities in the control unit's internal voltage supply or measurement.
- B1020 → Airbag control unit self-test error → The module cannot correctly check and initialize its own functionality.
- B1030 → Internal software error in the airbag control unit → Corruption or problem in the firmware or operating software of the control unit.
- B1100 → Airbag ECU calibration error → Error in the internal calibration of the sensors or logic of the control unit.
- B1200 → Memory overflow or data corruption error → Memory overload or corruption of critical system data.
What part numbers are available for the Daihatsu Terios J200 airbag control unit repair?
For Daihatsu Terios J200 airbag control unit repairs, three validated Daihatsu OEM part numbers are primarily relevant, ensuring compatibility with the J200 series (model years 2006-2018). These numbers are crucial for correct diagnosis and module replacement.
- 89170-B4080 (Daihatsu Genuine Airbag Control Unit)
- 89170-87428 (Daihatsu Airbag Module OEM No.)
- 89170-87407 (Daihatsu Airbag Module OEM No.)
These exact original OEM part numbers are verified for airbag control units for the Daihatsu Terios J200. There are no alternative part numbers from suppliers such as Bosch or Continental listed specifically for this airbag control unit for the J200.
A precise verification of the part number is essential for a successful Daihatsu Terios J200 airbag control unit repair to restore full functionality of the safety system and prevent failure. Specialized workshops can verify compatibility and perform a professional diagnosis.
