What is a Mitsubishi Strada KB airbag control unit?
The Mitsubishi Strada KB airbag control unit is your vehicle's central safety unit, activating all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors sensors, stores relevant crash data, and ensures the proper functioning of all airbag modules for your safety on the road.
This electronic control module is essential for safety in the Mitsubishi Strada KB. It communicates via the OBD-II interface, allowing error analysis and reset by diagnostic devices.
A powerful microcontroller is responsible for rapid crash detection and targeted airbag deployment. Repairs and software resets can be performed by specialists to restore functionality after an incident.
Why is the Mitsubishi Strada KB airbag control unit defective?
A Mitsubishi Strada KB airbag control unit often fails due to crash data being permanently stored after an accident, internal electronic errors, or short circuits in the airbag circuits. These problems prevent the airbag system from functioning properly and require professional repair or a module reset.
Common causes of failure are internal system errors affecting the control unit itself. This can occur due to aging components or overvoltage.
After an accident, the control unit signals a "Crash Detected" status (B1649), which can only be resolved by a reset. Without this reset, the airbag warning light remains active and the system is inactive.
Electrical short circuits in the airbag circuits, for example in connection with squibs or indicator lights, can also damage the control unit and make a Mitsubishi Strada KB airbag control unit repair necessary.
Common error codes for Mitsubishi Strada KB airbag control unit repair
A Mitsubishi Strada KB airbag control unit repair typically involves reading specific error codes that indicate internal problems with the control unit or its direct electrical connections. These codes help accurately diagnose the defect, whether it's an internal error or stored crash information.
The following codes are exclusive to errors directly related to the Mitsubishi Strada KB airbag control unit (ECU):
- B1015 → Faulty Airbag Module (internal fault in the control unit) → An internal defect in the airbag control unit of the Mitsubishi Strada KB.
- B1139 → SRS Module internal error (internal system error) → Indicates a fault within the SRS module, typically a malfunction of the airbag ECU.
- B1193 → Airbag module related fault → A general fault that originates directly from the airbag control unit and indicates a repair.
- B1206 → Airbag RCM (Restraint Control Module) fault → The RCM is another name for the airbag control module, which indicates a direct device failure.
- B1207 → Passenger Airbag Indicator Circuit Short → An electrical short in the control module affecting the passenger airbag warning light.
- B1342 → SRS system fault (general SRS system fault) → A general malfunction in the airbag system, often caused by the main control module.
- B1402 → Driver Airbag Squib grounding fault → A short circuit in the driver airbag squib grounding circuit, detected directly by the airbag control unit.
- B1620 → SRS error → A general error that indicates a problem within the SRS system, specifically the control module.
- B1649 → Crash detected (crash data stored in control unit) → Indicates that the control unit has registered an accident and stored crash data, which requires a reset.
What part numbers are available for the Mitsubishi Strada KB airbag control unit repair?
The only 100% verified and OEM-compliant part number for the Mitsubishi Strada KB airbag control unit that is relevant for repair is MR530002 DP from Denso. This number corresponds to an original component developed specifically for this vehicle model and confirmed in repair practice.
It is important to note that other common OEM manufacturers such as Bosch or Continental were unable to provide specific, verified part numbers for the Mitsubishi Strada KB airbag control unit.
Replacement or alternative part numbers with clear compatibility with the Mitsubishi Strada KB could also not be confirmed in this research. This underscores the uniqueness and specificity of the number MR530002 DP for the Mitsubishi Strada KB airbag control unit repair.
