Airbag control unit with part number 22674098

What does the airbag control unit 22674098 do?

The airbag control unit 22674098 is the control centre of the restraint system in Chevrolet vehicles. It checks the pulses from the impact sensors, selects the appropriate airbags and seatbelt pretensioners within milliseconds in an accident, and monitors the system continuously.

The unit indicates a fault via the airbag warning light. After an accident it stores crash data and locks itself; only the repair lifts this lock.

Why does the control unit 22674098 fail?

The crash data from an earlier accident is the most common cause for the 22674098. It stays stored even without a triggered airbag, and a normal diagnostic tool cannot remove it.

Additionally, ageing electronic components come into consideration, along with cold solder joints inside the unit.

Moisture and corrosion at plug connections, as well as voltage spikes, for example from a weak battery or jump-starting, can likewise lead to failure.

How can you tell that the 22674098 is defective?

A defect in the 22674098 shows up on the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Also present are an error message in the instrument cluster, a diagnostic tool without connection to the control unit, and a fault memory that cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may therefore fail to deploy. A warning like this should be checked promptly.
