Airbag control unit with part number 89170-48C60

What does the airbag control unit 89170-48C60 do?

The airbag control unit 89170-48C60 forms the evaluation unit in the SRS restraint system of Lexus. It evaluates the crash sensors, decides in a crash within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After an accident it stores crash data and locks itself.

If the electronics detect a fault, they make it visible via the airbag warning light in the instrument cluster.

Why does the control unit 89170-48C60 fail?

The most likely cause is crash data stored after an accident, even if no airbag has deployed. A standard diagnostic tool cannot erase it. Further causes are aged electronic components, cold solder joints, moisture and corrosion, and voltage spikes at the control unit 89170-48C60.

Crash data does not necessarily mean that a component is damaged. Which cause is actually present only becomes clear during the inspection on the test bench.

Aged electronics and cold solder joints are not visible from outside. Moisture and corrosion attack the plug connections, and voltage spikes arise, for example, with a weak battery or from a jump start.
