What is a Mazda CX-60 KH airbag control unit?
The Mazda CX-60 KH 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 provide maximum occupant safety.
This sophisticated control unit is specifically designed for the first generation Mazda CX-60 (model code KH, from 2022).
It processes signals from various sensors to decide in milliseconds whether to deploy airbags and seat belt pretensioners.
Why is the Mazda CX-60 KH airbag control unit defective?
A Mazda CX-60 KH airbag control unit can fail because it has stored crash data after an accident, preventing reuse, or due to internal malfunctions caused by aging, moisture damage, or overvoltage. These failures require specialized diagnostics and often a professional Mazda CX-60 KH airbag control unit repair.
After an accident, the crash data is permanently stored in the control unit, making reuse without a reset impossible.
Internal errors caused by component failure or software problems can also lead to system failure.
Moisture ingress or corrosion at the connections can also cause a defect in the airbag control unit.
Common error codes for Mazda CX-60 KH airbag control unit repair
