What is a Mitsubishi Colt CB airbag control unit?
The Mitsubishi Colt CB airbag control unit is the central safety unit in the vehicle, which activates all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors sensors in the vehicle, stores important crash data, and ensures the proper functioning of the entire airbag system for your safety.
This SRS module (Supplemental Restraint System) is crucial for the passive safety of your Mitsubishi Colt of the CB, CJ0 or VI (Z20, Z30) series.
It acts as the brain of the airbag system and processes signals from crash and acceleration sensors to respond precisely in an emergency.
Why is the Mitsubishi Colt CB airbag control unit defective?
A Mitsubishi Colt CB airbag control unit often fails due to crash data being permanently stored after an accident, internal electronic components failing due to age, or communication problems with other vehicle systems. These defects can block the system and cause a persistent airbag warning light, compromising vehicle safety.
After an airbag is deployed, the control unit stores indelible crash data, which requires repair or replacement of the module.
Even without an accident, internal electronic errors or overvoltage damage can paralyze the control unit, resulting in an error message.
Mechanical influences or moisture can also damage the sensitive electronics in the airbag control unit and impair its function.
Common error codes for Mitsubishi Colt CB airbag control unit repair
During Mitsubishi Colt CB airbag control unit repairs, specific error codes often occur, indicating problems with the steering wheel contact or control unit communication. These codes are crucial for diagnosis and indicate whether there is a defect in the control unit itself or in connected components.
- **Code 22 → Clock Spring (steering wheel contact) fault → Circuit open or damaged.** This fault is typically reported directly by the airbag control module and is a common trigger for the airbag warning light.
- **B1000 → Control unit communication error → General communication problem in the airbag system.** This indicates a faulty connection between the airbag control unit and other modules or an internal defect in the control unit itself.
- **"Crash data stored" → Control unit blocked (not resettable without service) → Requires specific repair or reset.** After an accident, the Mitsubishi Colt airbag control unit stores this data, which prevents standard erasure and requires a specialist workshop.
What part numbers are available for the Mitsubishi Colt CB airbag control unit repair?
For Mitsubishi Colt CB airbag control unit repairs, there are various original Mitsubishi part numbers as well as compatible OEM numbers from suppliers like Bosch. It is essential to match the exact part number of the defective unit to ensure compatibility and proper function of the airbag system.
Important Mitsubishi OEM part numbers for Colt CB, CJ0 and VI (Z20, Z30) include MR359828, MR587417, 97RA-0104822 and 8635A223.
