Airbag control unit with part number 89170-60D80

What does the airbag control unit 89170-60D80 do?

The airbag control unit 89170-60D80 controls the restraint system (SRS) for Toyota as a central unit. It evaluates the signals from the crash sensors and decides in an accident, within milliseconds, which airbags and seatbelt pretensioners are triggered.

In addition, it monitors the system continuously. It reports faults via the airbag warning light in the instrument cluster, so that a malfunction is noticed quickly.

After an accident, the unit stores crash data and locks itself. The following sections explain causes, signs and the course of the repair.

Why does the control unit 89170-60D80 fail?

Stored crash data is the most common cause, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Other causes include aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

Crash data is in the unit's memory after an accident, regardless of whether an airbag has deployed. Nevertheless, have the fault memory read out to clarify the situation.

The other causes affect the electronics: aged components, cold solder joints, moisture and corrosion on plug connections, as well as voltage spikes, for example from a weak battery or a jump start.

How can you tell that the 89170-60D80 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. In addition, a fault message appears in the instrument cluster, the diagnostic tool finds no connection to the control unit, or the fault memory cannot be cleared.

The warning light is the first sign you notice. A fault message or a fault memory that cannot be cleared confirms the suspicion and makes a check necessary.

In an emergency, airbags and seatbelt pretensioners may then fail to deploy. Therefore have the finding checked promptly.
