What is a Daihatsu Terios J210 airbag control unit?
The Daihatsu Terios J210 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It processes sensor signals, decides within milliseconds whether to deploy airbags and seatbelt pretensioners, and continuously monitors the status of all airbag components in the vehicle.
This module is the heart of the Supplemental Restraint System (SRS) and is therefore essential for the passive safety of the vehicle occupants.
It ensures communication with other safety modules and reports system errors via the vehicle's ECU monitoring system. A functioning airbag control unit repair is therefore critical.
Why is the Daihatsu Terios J210 airbag control unit defective?
The Daihatsu Terios J210 airbag control unit often fails because it stores crash data after an accident or has internal errors such as power supply and microcontroller problems. This causes the airbag warning light to stay permanently illuminated, making professional airbag control unit repair essential to ensure vehicle safety.
After a trigger, the control unit stores indelible crash data that requires special reprogramming.
Even without an accident, internal component defects or age-related wear and tear can lead to failure, requiring immediate diagnosis and repair.
Common error codes for Daihatsu Terios J210 airbag control unit repair
When repairing the Daihatsu Terios J210 airbag control unit, error codes often indicate problems with the module itself. Typical B codes like B1000 or B1001 indicate internal communication or memory errors that require specialized diagnosis and repair to restore vehicle safety.
- B1000 → Control unit communication error → Signal interruption or internal defect in the airbag ECU.
- B1001 → Internal memory error → Defect in the internal memory of the airbag control unit.
- B1010 → Power supply control unit faulty → Insufficient or unstable power supply to the airbag ECU.
- B1020 → Internal microcontroller error → Defect in the main processor of the airbag control unit.
- B1100 → Internal EEPROM Error → Error in the non-volatile memory of the airbag ECU.
- B1200 → Airbag ignition circuit error (not sensor) → Problem within the ignition circuit of the airbag control unit.
- B1300 → Airbag activation circuit error → Malfunction in the activation circuit of the airbag ECU.
These codes are crucial for an accurate diagnosis before initiating airbag control unit repair.
What part numbers are available for the Daihatsu Terios J210 airbag control unit repair?
For Daihatsu Terios J210 airbag control unit repairs, precise OEM part numbers are crucial. Only a few are securely verified. These numbers, from both Daihatsu and the supplier Takata, ensure the correct compatibility and functionality of the airbag system for your J210 vehicle model.
The only exact and verified OEM part numbers for the Daihatsu Terios J210 airbag control unit are:
- Daihatsu OEM : 89170-87427, 89170-87407
- Takata OEM supplier numbers : 152300-7180-93c56, 152300-4430-93c56
These numbers have been verified by independent sources such as SafetyRestore and are specific to the Terios J210. A proper airbag control unit repair requires the exact part number to ensure compatibility.
Other parts such as sensors were excluded because they are not the control unit itself. Replacement or alternative part numbers are rare for the airbag control unit because they are specifically coded.
