Airbag control unit with part number 89170-60A60

What does the airbag control unit 89170-60A60 do?

The airbag control unit 89170-60A60 controls the restraint system of Lexus as the SRS control unit. It evaluates the crash sensors, decides within milliseconds in an accident which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After an accident it stores crash data and locks itself.

The monitoring runs in the background, without you noticing anything. If the unit detects a fault, it displays it via the airbag warning light in the instrument cluster.

It connects the sensors with the triggers. If it fails, the protective effect of the entire system suffers.

Why does the control unit 89170-60A60 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed, because a normal diagnostic tool cannot erase it. Other causes include aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes, for example with a weak battery or jump-starting. During repair, Airbag24 erases the crash data.

Crash data shows that the unit has registered an accident. Whether any component is damaged beyond that can only be determined during testing.

The electronics react sensitively to moisture and voltage fluctuations. Even small faults in the plug connectors can therefore show up as a malfunction.

Aged components and cold solder joints are harder to detect, because they only show under certain conditions.

How can you tell that the 89170-60A60 is defective?

A defect shows itself through the airbag warning light, which lights up permanently or intermittently, through error messages in the instrument cluster, through a missing connection to the diagnostic tool, and through a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may not deploy.

Typical signs at a glance:

• airbag warning light in the instrument cluster, permanently or intermittently
• error message in the instrument cluster
• no connection between the diagnostic tool and the control unit
• fault memory that cannot be cleared

Take such signs seriously and look into them promptly.

On the one hand, compare the number on the label of the removed unit with this page; this only ensures that you have the matching unit. On the other hand, have the fault memory read out beforehand, because only the log shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 89170-60620, 89170-60630, 89170-60631, 89170-60F30.

How does the repair of the 89170-60A60 work?

Before removal, have the fault memory read out and enclose the log. Only then disconnect the battery and remove the control unit, and create a repair order online. Processing at Airbag24 takes 3–4 working days as a rule.

Safety dictates the sequence: the unit may only be removed once the battery has been disconnected.

Airbag24 tests the unit on the test bench, replaces defective components, erases stored crash data and carries out a function test. Afterwards your own unit returns to you.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit 89170-60A60 get to Airbag24?

You can send the control unit as a parcel or book a UPS collection for an extra charge. Airbag24 handles the return after the repair by UPS.

Pack the unit shock-resistant and add the printed repair order.
