What is a Mitsubishi Carisma DA airbag control unit?
The Mitsubishi Carisma DA airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It monitors sensors, stores crash data, and ensures the proper functioning of all airbag modules in the vehicle to ensure maximum safety.
This essential module, often manufactured by Bosch, manages the entire Supplemental Restraint System (SRS) of your Mitsubishi Carisma DA.
It processes real-time data from impact sensors and is responsible for the precise and timely deployment of airbags and seat belt pretensioners.
Why is the Mitsubishi Carisma DA airbag control unit defective?
A Mitsubishi Carisma DA airbag control unit is often defective because it stores crash data after an accident, internal electronic errors occur due to aging or voltage spikes, or moisture causes corrosion. Repairing the airbag control unit is a cost-effective and safe alternative to replacing the defective module.
After a collision, the control unit stores the crash information and usually needs to be reset or repaired to become fully functional again.
Other causes of failure include age-related wear and tear of electronic components, short circuits or even water ingress, which can damage the sensitive internal components of the control unit and make repairs necessary.
Common error codes for Mitsubishi Carisma DA airbag control unit repair
When repairing a Mitsubishi Carisma DA airbag control unit, specific error codes are crucial for a precise diagnosis, as they directly indicate problems within the control unit itself or its circuitry. These codes help clearly identify a defect and repair it specifically, rather than simply treating symptoms.
- B1000 → Control unit communication error → A malfunction in the data connection between the airbag control unit and other systems or diagnostic devices.
- B1207 → Passenger Airbag Indicator Short Circuit → An electrical short in the passenger airbag indicator light circuit.
- B1208 → LCD Heater Control Unit → A fault in the internal heating circuit of the LCD display of the control unit.
- B1209 → Test mode active → The control unit is permanently in test mode, which prevents normal function.
- B1300 → Topstack Switch Error → A problem with an internal switch or sensor within the airbag control module.
- B1402 → Driver Side Airbag Circuit Squib → An open or short circuit in the driver side airbag deployment circuit, often caused by a faulty control module or clock spring.

Function and technical data of the Mitsubishi Carisma DA airbag control unit
The Mitsubishi Carisma DA airbag control unit continuously monitors the entire airbag system, processes signals from crash sensors, and deploys the airbags as needed to protect occupants. It operates on 12V vehicle voltage and is central to your vehicle's passive safety, so prompt repair in the event of a failure is crucial.
It integrates signals from all crash sensors as well as information about seat occupancy and belt tensioners to ensure targeted activation of the restraint systems.
The control unit has extensive diagnostic capabilities, stores error codes, and often needs to be remarried and reprogrammed to the vehicle after a replacement or repair.
Compatibility and installation position for the Mitsubishi Carisma DA airbag control unit repair
The Mitsubishi Carisma DA airbag control unit is specifically designed for the 1996 to 2006 Mitsubishi Carisma DA sedan and is typically located inside the vehicle, often under the passenger seat or center console. Precise fit and installation position are critical for functionality and a successful repair.
It is compatible with various engine variants such as 1.8 GDI, 1.8 16V and 1.9 DI-D, although different control unit versions may exist depending on the specific equipment and year of manufacture.
The installation location is strategically chosen to ensure short cable routes to the sensors and airbags, which optimizes signal transmission and ensures a fast system response.
Important information about Mitsubishi Carisma DA airbag control unit repair
A professional Mitsubishi Carisma DA airbag control unit repair requires specialized knowledge and equipment, as improper handling poses safety risks and can cause malfunctions. It is essential to disconnect the battery before working on the system and use professional diagnostic equipment for reliable error reading and programming.
Repairs typically involve resetting crash data and restoring the original system function, which is often a cost-effective alternative to purchasing a new unit, especially if the old control unit only has a single fault.
To avoid damage and misleading error codes, the control unit should never be electrically tested without the designated airbag resistors, which is why repairs in a specialized workshop are recommended.
