Airbag control unit with part number 28556 JR60C

What does the airbag control unit 28556 JR60C do?

The 28556 JR60C is the airbag control unit that controls the restraint system in vehicles from Nissan. It evaluates the crash sensors, decides within milliseconds in an accident which airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

If it detects a fault, it displays this via the airbag warning light. After an accident it stores crash data and locks itself; this lock only ends with the repair.

Why does the control unit 28556 JR60C fail?

The most common trigger for a failure of the 28556 JR60C is crash data stored after an accident, even if no airbag has fired. A normal diagnostic tool cannot erase it.

Aged electronic components and cold solder joints can also lead to failure. Moisture and corrosion at plug connections have a similar effect, and voltage spikes, for example from a weak battery or jump-starting, put additional strain on the unit.

Airbag24 erases the crash data as part of the repair.

How can you tell that the 28556 JR60C is defective?

A defect in the 28556 JR60C shows as the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Accompanying signs are a fault message in the instrument cluster, no connection to the diagnostic tool, and a fault memory that cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then fail to deploy. If you notice these signs, have the system checked promptly.
