What is a Mitsubishi Eclipse D30 airbag control unit?
The Mitsubishi Eclipse D30 airbag control unit is your vehicle's central safety unit, activating all occupant restraint systems, such as airbags and seatbelt pretensioners, after an accident. It continuously monitors sensors, stores crash data, and ensures the correct functioning of the SRS system, essential for a reliable Mitsubishi Eclipse D30 airbag control unit repair.
This electronic control unit (ECU) is specifically designed for the Supplemental Restraint System (SRS) in the 2nd generation Mitsubishi Eclipse (D30, model years 1995-1999). It works closely with all safety sensors.
The module registers impact events and decides within milliseconds whether to activate the passive safety systems. This effectively protects the occupants in the event of a collision.
Why is the Mitsubishi Eclipse D30 airbag control unit defective?
A Mitsubishi Eclipse D30 airbag control unit often fails because it stores crash data after an accident and then blocks it, or is affected by internal malfunctions such as age-related electronic defects or water damage. This triggers the airbag warning light and requires a professional Mitsubishi Eclipse D30 airbag control unit repair.
After airbags are deployed, the control unit stores indelible crash data, making replacement or resetting essential. Without this service, the SRS system remains inactive.
Other causes can include short circuits in the vehicle's electrical system, defective sensors, or age-related material fatigue of internal components. This can lead to malfunctions and the activation of the warning light.
Common error codes for Mitsubishi Eclipse D30 airbag control unit repair
When repairing the Mitsubishi Eclipse D30 airbag control unit, specific B-codes are crucial because they indicate problems within the SRS module itself. These trouble codes are stored by the control unit and can enable a precise diagnosis to identify and resolve the cause of the airbag warning light.
- B1207 → Passenger airbag indicator circuit short circuit → Passenger airbag indicator circuit malfunction or short circuit.
- B1208 → LCD heater circuit error → Problem with the LCD heater circuit of the airbag control unit.
- B1209 → Test mode active → The control unit is in programming or diagnostic mode.
- B1402 → Driver airbag squib ground fault → Poor ground contact, defective driver airbag or slip ring (clock spring).
What part numbers are available for the Mitsubishi Eclipse D30 airbag control unit repair?
For Mitsubishi Eclipse D30 airbag control unit repairs, the exact Mitsubishi OEM part numbers MR243890 and MB914217 are crucial for compatibility. These specific numbers ensure you receive the correct airbag control unit for your vehicle and a successful repair is possible.
Part number MR243890 is multi-validated as a genuine airbag control unit part for Mitsubishi Eclipse (D30 series, approximately 1995-2000). It refers to the complete control unit, not just a sensor.
Likewise, the number MB914217 has been confirmed as an OEM part number for a control unit in the D30 Mitsubishi Eclipse. Both numbers are crucial for a precise fit.
No other specific OEM or spare part numbers from suppliers such as Bosch, Continental, or Autoliv could be verified specifically for the D30 airbag control unit. Always ensure that the part matches the series-specific part when replacing.
