Airbag control unit with part number 89170-60151

What does the airbag control unit 89170-60151 do?

The airbag control unit 89170-60151 is the central control unit of the restraint system (SRS) of Lexus. It evaluates the crash sensors, decides in a crash whether airbags and seatbelt pretensioners are triggered, and monitors the system constantly. It reports faults via the airbag warning light.

After an accident the unit stores crash data and locks itself. The protective effect of the entire system depends on this component working.

Why does the control unit 89170-60151 fail?

Stored crash data from an accident is the most common cause in the control unit 89170-60151, even if no airbag was deployed. Other causes include aged components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

A normal diagnostic tool cannot erase this crash data. Airbag24 erases it during the repair; you do not need to take any action for this.

Aged electronic components and cold solder joints lead to failures over time. Voltage spikes, for example from a weak battery or a jump start, put additional strain on the unit.

How can you tell that the 89170-60151 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently when there is a defect in the 89170-60151.

In addition there are fault messages in the instrument cluster, a diagnostic tool that cannot establish a connection to the control unit, and a fault memory that cannot be erased.

Airbags and seatbelt pretensioners may then fail to trigger in an emergency. The warning light is therefore a warning sign that must be taken seriously.
