Airbag control unit with part number 28556 1U60C

What does the airbag control unit 28556 1U60C do?

In the restraint system of Nissan, the airbag control unit 28556 1U60C works as the central control unit. It evaluates the crash sensors, selects within milliseconds the airbags and seatbelt pretensioners that fire in an accident, and monitors the entire system.

If it detects a fault, it reports this via the airbag warning light in the instrument cluster. After an accident it also stores crash data and locks itself.

The monitoring runs without interruption during operation, so a fault can be noticed early.

Why does the control unit 28556 1U60C fail?

The most common trigger for the 28556 1U60C is crash data from an accident that remains stored in the unit, even if no airbag has deployed. A normal diagnostic tool cannot erase it.

These entries explain many cases in which the fault persists despite all attempts.

In addition, aged electronic components, cold solder joints, and humidity or corrosion at plug connectors come into question.

Voltage spikes, for example from a weak battery or after a jump-start, can also affect the control unit.

How can you tell that the 28556 1U60C is defective?

The airbag warning light in the instrument cluster lights up on the 28556 1U60C permanently or only intermittently, as soon as something in the control unit is wrong. In addition there are fault messages in the instrument cluster or a fault memory that cannot be cleared.

A diagnostic tool that cannot establish a connection to the control unit is also a warning sign. In an emergency, airbags and seatbelt pretensioners may then not deploy, which is why such findings should be checked promptly.
