What is a Daewoo Matiz M150 airbag control unit?
The Daewoo Matiz M150 airbag control unit is the central control unit for the occupant restraint system. It monitors sensors, decides on airbag deployment in the event of an accident, and stores crash data. Proper functioning is crucial for your safety and a must for any Daewoo Matiz M150 airbag control unit repair.
This robust module is crucial for the vehicle's passive safety and is often located centrally in the dashboard or center console. It is designed to function reliably even under extreme loads.
The control unit communicates with various components such as acceleration sensors, the driver and passenger airbags, and the seat belt pretensioners. It is an integral part of the 12V electrical system and the vehicle diagnostic interface.
Why is the Daewoo Matiz M150 airbag control unit defective?
Your Daewoo Matiz M150 airbag control unit may be defective because, after an accident, a crash data record is stored internally, preventing further use without a reset. Internal memory errors (EEPROM) or power supply problems can also lead to failure, necessitating a Daewoo Matiz M150 airbag control unit repair.
A common cause of malfunction is an airbag deployment, which leaves an irretrievable "crash record" in the internal memory. This must be professionally erased to make the system operational again.
Other causes of a faulty control unit include internal logic errors, power supply issues, or faulty self-tests. These malfunctions often cause the airbag warning light to stay lit or flash.
In such cases, a precise diagnosis at a workshop is essential to determine whether the module needs to be replaced or repaired. Correcting these errors is part of the comprehensive Daewoo Matiz M150 airbag control unit repair.
Common error codes for Daewoo Matiz M150 airbag control unit repair
During a Daewoo Matiz M150 airbag control unit repair, specific error codes are often read out, indicating internal problems with the airbag ECU. These codes often signal a crash record, communication errors, or problems with the unit's internal memory and power supply.
- B1000 → Control unit communication error → Airbag ECU
- B1010 → EEPROM memory error control unit → Airbag ECU
- B1100 → Internal crash data record saved → Airbag ECU
- B1200 → Logic error in the control unit → Airbag ECU
- B1300 → Power supply error → Airbag ECU
- B1400 → Self-test error control unit → Airbag ECU
- B1500 → Memory Read/Write Error → Airbag ECU
For example, an error code like B1100 means that a crash event has been logged and the control unit needs to be reset. This is a typical reason why a Daewoo Matiz M150 airbag control unit repair is necessary.
What part numbers are available for the Daewoo Matiz M150 airbag control unit repair?
For Daewoo Matiz M150 airbag control unit repairs, several verified OEM and supplier part numbers are relevant to ensure exact compatibility. These numbers identify the specific control unit and are crucial for sourcing the correct replacement part, whether new, used, or for a reset service.
The original Daewoo OEM part numbers for the Matiz M150 airbag control unit include 96603738, 96314931, 96219056CN, and 96484976. These are confirmed by various reputable sources and cover the M100 and M150 model series.
Suppliers like Autoliv also produce OEM-compatible control units. Part numbers like 96801172 and 96 801 132 are common and are often used in professional Daewoo Matiz M150 airbag control unit repairs.
It is crucial to match the exact part number with the existing control unit to ensure proper airbag system function after repair. Each of these numbers represents a specific airbag control unit, not sensors.
