What is a Mitsubishi Montero V60 airbag control unit?
The Mitsubishi Montero V60 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It continuously monitors sensors, detects collisions in milliseconds, stores important crash data, and ensures the proper and safe deployment of all airbag modules and seatbelt pretensioners in the vehicle.
This electronic control unit, also known as the SRS module or airbag computer, continuously monitors signals from impact and deceleration sensors.
When a defined threshold is reached, it decides whether to deploy the airbags and sends precise control commands to the corresponding deployment units.
The module also performs self-diagnosis and stores error codes that, in the event of defects, activate the airbag warning light in the dashboard.
Why is the Mitsubishi Montero V60 airbag control unit defective?
A Mitsubishi Montero V60 airbag control unit often fails because it stores irreversible crash data after an accident, which permanently activates the airbag warning light. Other causes include overvoltage damage, moisture ingress, or age-related internal faults, which then impair the functionality of the entire safety system and require professional repair of the module.
A common reason for failure is the storage of crash data after deployment, even if the airbags have not been visibly deployed.
Moisture or corrosion in the control unit, often caused by water ingress in the footwell, can damage electronic components and cause short circuits.
Age-related fatigue of electronic components or overvoltages in the vehicle electrical system can also cause a defect in the airbag control unit, which requires specialized repair.
Common error codes for Mitsubishi Montero V60 airbag control unit repair
When repairing a Mitsubishi Montero V60 airbag control unit, specific error codes are crucial because they indicate internal defects within the module itself. These codes relate exclusively to the control unit and not to external sensors or components. Their correct interpretation enables a precise diagnosis and the targeted restoration of full functionality of your airbag system.
- B1000 → Control unit communication error → Defective airbag control unit or faulty connection.
- B1207 → Passenger Airbag Indicator Circuit Shorted → Short circuit in the passenger airbag indicator circuit, often an internal control unit fault.
- B1208 → LCD Heater → Internal error in the airbag control unit circuit.
- B1209 → Test Mode → Control unit is blocked in test mode, indicates an internal error.
- B1300 → Topstack Switch → Internal switch error in the airbag control unit.
- B1309 → Timeout Error (5bow up) → Communication timeout or internal processor problems of the module.
- B1402 → Driver Airbag Squib Grounding Fault → Error in the driver airbag squib circuit, can originate from the control unit.
- 93F9 → Internal error in the airbag control unit → Serious hardware defect or overvoltage damage.
- 65535 → Airbag control unit defective / No communication → Total failure of the module, no communication possible.
