Airbag control unit with part number 89170-06180

What does the airbag control unit 89170-06180 do?

The airbag control unit 89170-06180 controls the restraint system (SRS) for Toyota. It evaluates crash sensors, decides within milliseconds in an impact which airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

If a fault occurs, the unit shows it via the airbag warning light in the instrument cluster. In this way you receive the notice without having to connect a diagnostic tool.

After an accident, the control unit stores crash data and locks itself. The lock is part of the function of the system and is checked during the repair.

Why does the control unit 89170-06180 fail?

The most common cause is crash data stored after an accident, and this cannot be removed with an ordinary diagnostic tool. Other causes are:

Besides the crash data, various causes come into consideration that stress the unit over the years.

• ageing of the electronic components
• cold solder joints on the circuit board
• moisture and corrosion on plug connections
• voltage spikes, for example from a weak battery or jump-starting

Whether one of these causes is present is shown only by the readout and a subsequent inspection of the control unit.

How can you tell that the 89170-06180 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently. A fault message in the instrument cluster and a diagnostic tool without connection to the control unit are further signs. A fault memory that cannot be cleared also belongs to this.

The warning light is the signal you should notice first. It indicates that the restraint system has detected a fault, and then a check is advisable.

Airbags and seatbelt pretensioners may possibly not deploy in an emergency if the control unit is defective. For this reason, do not ignore the warning.
