What is a Daihatsu Move Latte L550 airbag control unit?
The Daihatsu Move Latte L550 airbag control unit is the central safety unit that activates all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors sensors in the vehicle, stores important crash data, and ensures the proper functioning of all airbag modules for maximum occupant safety.
This electronic module is specifically designed for the Daihatsu Move Latte L550 series (model years 2004-2009). It processes signals from crash sensors and deploys the airbags when necessary to protect the occupants.
In addition, the control unit communicates with the vehicle's diagnostic system and stores error codes, enabling precise diagnosis of defects. Repairing the Daihatsu Move Latte L550 airbag control unit is often a cost-effective alternative to purchasing a new one.
Why is the Daihatsu Move Latte L550 airbag control unit defective?
The Daihatsu Move Latte L550 airbag control unit may be defective because it stores crash data after an accident, requiring reprogramming, or internal components may fail due to overvoltage or aging. A defect can also be caused by moisture ingress or software errors, which impair the functionality of the entire airbag system and require immediate repair.
Common causes of failure include the storage of so-called "crash data" after an impact, which blocks the control unit. Internal electronic errors, for example, in the microcontroller or flash memory, can also lead to a malfunction.
Moisture or corrosion at the connectors, as well as voltage fluctuations in the vehicle electrical system, can damage the sensitive electronics. In such cases, a professional diagnosis and specialized repair of the Daihatsu Move Latte L550 airbag control unit is essential to restore safety.
Common error codes for Daihatsu Move Latte L550 airbag control unit repair
A Daihatsu Move Latte L550 airbag control unit repair typically involves reading specific B-codes that indicate direct problems with the ECU or its primary deployment circuits. These trouble codes help identify communication errors, high or low resistance in the squib circuits, and short circuits that indicate airbag system malfunction.
- B1000 → Control unit communication error → Often caused by internal defects in the control unit or problems in the power supply/wiring harness.
- B0001 → Driver Airbag Squib Circuit Resistance High → Indicates an open circuit in the driver airbag circuit or a faulty airbag squib.
- B0002 → Driver airbag squib circuit resistance low → May indicate a short in the driver airbag circuit or an internal malfunction in the airbag module.
- B0010 → Driver Airbag Squib Circuit Short to Ground → A problem in which the driver airbag squib circuit makes unauthorized contact with the vehicle ground.
- B0011 → Driver airbag squib circuit short to battery → Indicates a direct contact of the driver airbag squib circuit to the battery voltage.
- B0016 → Passenger Airbag Squib Circuit Resistance High → Indicates an open circuit in the passenger airbag circuit or a faulty squib.
- B0018 → Passenger airbag igniter circuit short circuit to battery → Means unwanted contact of the passenger airbag igniter circuit with the battery voltage.
- B1884 → SRS lamp failure → Indicates a malfunction of the airbag indicator lamp, which is an important warning signal.
