What is a Mitsubishi eK Wagon H82W airbag control unit?
The Mitsubishi eK Wagon H82W airbag control unit is the central safety unit in the vehicle, activating all occupant restraint systems in the event of an accident. It continuously monitors sensors, processes data, and initiates the deployment of the airbags and seatbelt pretensioners to protect occupants as quickly as possible.
This electronic component is specifically designed for the Mitsubishi eK Wagon H82W, which is typically equipped with a 660 cc gasoline engine. It integrates into the vehicle's bus system, often via CAN bus, to communicate with other control units and safety systems.
Its primary function is the real-time processing of signals from front and side impact sensors, as well as G-force sensors. This enables precise detection of an accident situation and immediate activation of passive safety features.
Why is the Mitsubishi eK Wagon H82W airbag control unit defective?
A Mitsubishi eK Wagon H82W airbag control unit can fail due to internal memory errors, faulty power supplies, or software issues. Crash data stored after an accident, which is often irreversible, may also require repair or replacement to restore airbag system function and resolve error codes.
Typical causes of malfunction include internal damage due to aging or overvoltage in the vehicle electrical system. Such problems can lead to communication problems with other vehicle systems or the failure of diagnostic tests.
After an accident, the airbag control unit stores crash data that often cannot be easily reset. In such cases, reconditioning or replacement of the module is necessary to ensure the full functionality of the safety components and prevent accidental deployment.
Common error codes for Mitsubishi eK Wagon H82W airbag control unit repair
During Mitsubishi eK Wagon H82W airbag control unit repair, specific error codes indicate problems directly related to the control unit. These include communication errors, internal memory errors, power supply issues, or airbag system software problems that require a precise diagnosis.
- B1000 → Control unit communication error → Error in data transmission to the airbag ECU
- B1025 → Internal memory error of the airbag control unit → Damage or corruption in the internal data memory
- B1100 → Malfunction in the airbag sensor interface → Problems connecting to or processing sensor data
- B1610 → Faulty power supply to the airbag control unit → Insufficient or interrupted power supply to the ECU
- B1620 → Error in the airbag control unit software → Software inconsistency or program error in the control unit
- B1633 → Short circuit in the airbag control unit circuit → Electrical short circuit within the control unit or its wiring
- B1650 → Configuration error in the airbag control unit → Incorrect or incomplete programming of the module
- B1700 → Memory read error in the airbag ECU → Inability to read stored data from the internal memory
What part numbers are available for the Mitsubishi eK Wagon H82W airbag control unit repair?
For Mitsubishi eK Wagon H82W airbag control unit repairs, exact OEM part numbers are crucial because the component is safety-critical. Currently, no 100% verified, explicit OEM part numbers are available from publicly accessible sources. Identification requires verification of the vehicle identification number (VIN) in official Mitsubishi catalogs or TecDoc.
The exact part number is vehicle-specific and may vary depending on the year and equipment. For a safe repair, it is essential to rely on verified sources such as official Mitsubishi parts dealers or authorized workshops.
Suppliers such as Bosch, Continental, or Autoliv manufacture these control units and may offer alternative part numbers. An example, but unconfirmed, part number for the H82W Airbag SRS Computer is 8635A101DP8, which is for illustrative purposes only but must be verified before use.
