What does the airbag control unit 89170-26310 do?

The airbag control unit 89170-26310 runs the restraint system (SRS) in the Toyota. It evaluates the crash sensors, determines the triggering of the airbags and seatbelt pretensioners within milliseconds, and monitors the system continuously.

The unit works in the background and intervenes only in a crash. This role makes the evaluation of the sensor signals so important.

It reports faults via the airbag warning light in the instrument cluster. After an accident, it stores crash data and locks itself.

Why does the control unit 89170-26310 fail?

Stored crash data is the most common cause with the 89170-26310, even if no airbag has been triggered; in addition come aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

A normal diagnostic tool cannot erase this crash data. Airbag24 takes over the erasure during the repair.

Voltage spikes, for example from a weak battery or a jump start, load the electronics additionally.
