What is a Mitsubishi Lancer Evolution VI airbag control unit?
The Mitsubishi Lancer Evolution VI airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It continuously monitors sensors, stores relevant crash data, and ensures the proper functioning of all airbag modules and seatbelt pretensioners in the vehicle, which is crucial for safety.
This microprocessor-controlled module is the brain of the Supplemental Restraint System (SRS) in your Mitsubishi Lancer Evolution VI.
It processes signals from acceleration and impact sensors at lightning speed to make precise decisions about airbag deployment in an emergency.
Why is the Mitsubishi Lancer Evolution VI airbag control unit defective?
A Mitsubishi Lancer Evolution VI airbag control unit often fails because it is triggered by a system-related fault after an accident, thus becoming permanently deactivated. Internal electronic component defects, age-related wear, or short circuits in the connected circuits can also lead to a failure of the safety-relevant unit, necessitating a Mitsubishi Lancer Evolution VI airbag control unit repair.
After an airbag is deployed, the control unit stores crash data and must be replaced or professionally repaired.
Other common causes of failure include overvoltage, moisture damage, or corrosion of internal components that impair function.
A defective control unit usually causes the SRS warning light on the dashboard to illuminate and impairs the safety of the vehicle.
Common error codes for Mitsubishi Lancer Evolution VI airbag control unit repair
Common error codes during Mitsubishi Lancer Evolution VI airbag control unit repair indicate internal malfunctions within the control unit itself or problems with the associated electrical circuits. These specific B-codes are crucial for a precise diagnosis, as they signal specific failures in the airbag system and thus facilitate the determination of the cause of the failure.
Reading these codes is the first step in determining the exact cause of a defect and performing a targeted Mitsubishi Lancer Evolution VI airbag control unit repair.
A professional diagnostic tool can identify these system-specific error codes and thus help assess the condition of the airbag control unit.
- B1000 : Control unit communication error → Signals a problem in the internal communication of the airbag control unit itself.
- B1207 : Passenger Airbag Indicator Circuit Short → Indicates a short circuit in the passenger airbag indicator circuit.
- B1402 : Driver Airbag squib grounding → Indicates a fault in the driver airbag circuit, often a grounding problem.
What part numbers are available for the Mitsubishi Lancer Evolution VI airbag control unit repair?
For Mitsubishi Lancer Evolution VI airbag control unit repairs, the original Mitsubishi part numbers MR472773 and, to a limited extent, MR583376 are primarily relevant. These numbers identify the specific modules and are crucial for compatibility, with MR472773 being uniquely verified for the Evo VI model and preferred for reliable repairs.
The part number MR472773 is listed in official Mitsubishi parts catalogs as the airbag control unit for the Lancer Evolution VI (CP9A) and offers the highest level of compatibility assurance.
The number MR583376 is often listed for Evo VII-IX models, but may also be compatible with the Evo VI; however, careful checking before installation is essential to avoid failure.
It is important to note that airbag control units are often coded to the vehicle specific vehicle identification number (VIN).
When replacing a control unit, an adjustment or reset by a specialized workshop is often necessary to avoid error messages and ensure the full functionality of the system.
