Airbag control unit with part number 89170-0D600

What does the airbag control unit 89170-0D600 do?

The airbag control unit 89170-0D600 controls the restraint system (SRS) of Toyota. It reads the crash sensors, determines in a crash within fractions of a second which airbags and seatbelt pretensioners are triggered, and monitors the entire system.

If it detects a fault, it reports it via the airbag warning light in the instrument cluster.

After an accident, it stores crash data and locks itself. The lock is only lifted by a repair.

Why does the control unit 89170-0D600 fail?

The most common cause on the 89170-0D600 is crash data stored after an accident, even if no airbag has fired. Other causes include aged electronics, cold solder joints, moisture and corrosion on connectors, and voltage spikes.

Crash data cannot be erased with a normal diagnostic tool. Beyond this, the following causes come mainly into consideration:

• aged electronic components
• cold or cracked solder joints
• moisture and corrosion on plug connections
• voltage spikes, for example with a weak battery or jump-starting

How can you tell that the 89170-0D600 is defective?

The airbag warning light in the instrument cluster lights up on the 89170-0D600 permanently or intermittently. Further signs include an error message, no connection to the diagnostic tool and a fault memory that cannot be cleared. In an emergency, the airbags and seatbelt pretensioners may then fail to deploy.

The signs in detail:

• airbag warning light on permanently or intermittently
