Airbag control unit with part number 89170-0DA60

What does the airbag control unit 89170-0DA60 do?

The airbag control unit 89170-0DA60 works within the restraint system (SRS) of Toyota. It checks the signals from the crash sensors, determines in a crash which airbags and seatbelt pretensioners are triggered, and watches over the entire system. After an accident it stores crash data and locks itself.

The system reports faults itself to the airbag warning light in the instrument cluster. The unit is therefore the link between sensors, firing circuits and warning display.

Monitoring runs in the background as long as the system is supplied, and reacts immediately when needed.

Why does the control unit 89170-0DA60 fail?

The most common cause is stored crash data after an accident, even if no airbag triggered; a standard diagnostic tool cannot clear it. Other causes concern the electronics themselves, the plug connections and the power supply. The 89170-0DA60 is repaired at Airbag24, and during this the crash data are erased.

Further possible causes are:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

Crash data cannot be removed with a standard diagnostic tool. The cause therefore remains stored until the repair has been carried out.

How can you tell that the 89170-0DA60 is defective?

A clear sign is the airbag warning light in the instrument cluster, which lights up permanently or intermittently. An error message in the instrument cluster and a diagnostic tool without connection to the 89170-0DA60 can also occur. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

The following signs indicate a fault:

• airbag warning light on permanently or intermittently
• error message in the instrument cluster
• diagnostic tool does not find the control unit
• fault memory cannot be cleared

If you notice any of these signs, have the system checked promptly, because the light is the unit's warning to you.
