Airbag control unit with part number 28556-68K10

What does the airbag control unit 28556-68K10 do?

The airbag control unit 28556-68K10 is the control unit of the restraint system (SRS) in Nissan. It processes the signals from the crash sensors and determines within milliseconds in an accident which airbags and seatbelt pretensioners are triggered. After an accident, it stores crash data and locks itself.

The unit monitors the entire system permanently, even when the vehicle is standing. This includes the power supply, sensors and firing circuits.

A detected fault is stored and shown via the airbag warning light in the instrument cluster.

Why does the control unit 28556-68K10 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool does not erase it. In addition there are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example when the battery is weak or a jump start was needed.

Crash data remains stored in the unit after an accident, even if the vehicle then continues to drive without any irregularities. Airbag24 erases it during the repair.

The other causes can show up over a longer period. Ageing components and cold solder joints produce irregular faults, while moisture and corrosion weaken the contact at plug connections.

Voltage spikes also stress the electronics, for example when the battery is weak or a jump start was necessary.

How can you tell that the 28556-68K10 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. In addition, the instrument cluster shows a fault message, the diagnostic tool cannot establish a connection to the control unit, and the fault memory cannot be cleared.

The airbag warning light in the instrument cluster is the most noticeable sign. It burns permanently or only comes on from time to time.

A fault message in the instrument cluster, a missing connection to the diagnostic tool or a fault memory that cannot be cleared also count as signs.

In an emergency, airbags and seatbelt pretensioners may fail to deploy. The check should therefore be scheduled promptly.
