What is a Mitsubishi Pajero iO H60 airbag control unit?
The Mitsubishi Pajero iO H60 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It precisely monitors sensor data, stores important crash information, and ensures the proper functioning of all airbag modules and seatbelt pretensioners in the vehicle to provide maximum occupant safety.
This essential component is responsible for the rapid and coordinated activation of safety systems in the event of an impact.
It processes signals from acceleration sensors and communicates with other control units in the vehicle via the CAN bus.
Why is the Mitsubishi Pajero iO H60 airbag control unit defective?
A Mitsubishi Pajero iO H60 airbag control unit can malfunction due to internal electronic errors, power surges, or crash data stored after an accident. This often causes the airbag warning light to illuminate and compromises vehicle safety, requiring immediate repair.
Common causes of failure include aging of components, moisture damage or disruptions in the power supply of the vehicle electrical system.
A control unit can also be broken if it was involved in an accident and crash data is now permanently stored, making a reset or repair unavoidable.
