What is a Mitsubishi Mirage CL airbag control unit?
The Mitsubishi Mirage CL airbag control unit is the central safety unit in the vehicle, precisely activating occupant restraint systems such as airbags and seatbelt pretensioners in the event of an accident. It continuously monitors sensors and stores relevant crash data, ensuring the proper functioning and safety of all passive protection systems for the vehicle's occupants.
It serves as the "brain" of the Supplemental Restraint System (SRS), evaluating signals from impact sensors. Based on this data, it decides in milliseconds whether to deploy the airbags.
This module is relevant for Mitsubishi Mirage models built between 2015 and 2025. It is often compatible with similar variants such as the Mitsubishi Space Star.
Why is the Mitsubishi Mirage CL airbag control unit defective?
A Mitsubishi Mirage CL airbag control unit often fails due to internal errors, such as memory problems or electronic malfunctions. After an accident, it also stores crash data that requires a reset or replacement to deactivate system functionality and the warning light.
Common causes include internal system errors or age-related wear and tear on electronic components. Voltage fluctuations or water ingress can also damage the sensitive electronics.
After a vehicle accident, the control unit is often blocked because it permanently stores crash data. A malfunction can be indicated by a permanently illuminated airbag warning light on the dashboard.
Common error codes for Mitsubishi Mirage CL airbag control unit repair
When repairing the Mitsubishi Mirage CL airbag control unit, specific B error codes may occur, which directly indicate internal problems with the control unit. These codes, such as B1000 or B1001, signal typical electronic malfunctions or memory problems within the unit itself.
- B1000 → Control unit communication error → Indicates problems with the internal data transmission of the airbag ECU.
- B1001 → Internal memory error → Indicates a faulty function of the internal memory in the control unit.
- B1002 → Airbag diagnostic circuit error → Indicates a problem in the control module's self-test or diagnostic circuit.
- B1003 → Internal self-test error → The internal self-test of the control unit failed.
- B1004 → EEPROM memory error → A problem with the non-volatile memory of the airbag control unit.
- B1006 → Airbag ECU power supply error → The control unit is not receiving the correct power supply or has an internal supply problem.
- B1010 → Control unit internal acceleration sensor signal problem → The control unit incorrectly interprets acceleration sensor data, an internal error.
- B1020 → Error in data transmission to the airbag → Problems with the internal data transmission to the airbag modules from the control unit.
- B1030 → Internal uplink error → Signals an internal communication error in the control unit itself.
What part numbers are available for the Mitsubishi Mirage CL airbag control unit repair?
For the repair or replacement of a Mitsubishi Mirage CL airbag control unit, the OEM part numbers 8635A374, 8635A495MQ101, and the alternative OEM number W2T68771 are relevant. These numbers identify genuine Mitsubishi control units that are precisely tailored to the vehicle models and are crucial for safe operation.
It is crucial to carefully compare the part number of the defective module to ensure correct compatibility. These numbers have been confirmed as genuine and verified by trusted sources.
Airbag control units are VIN-coded, which means specific programming is required after replacement. This programming must be performed by a Mitsubishi dealer or specialized workshop.
Used and tested modules are often a cost-effective alternative to new parts. They often come with a warranty and require a professional crash data reset before installation.
