Airbag control unit with part number 68085880AH

What does the airbag control unit 68085880AH do?

The airbag control unit 68085880AH coordinates the SRS restraint system of Dodge. In a crash it evaluates the sensor signals and determines within milliseconds which airbags and seatbelt pretensioners are triggered.

The monitoring of the system runs continuously in the background. The unit reports faults via the airbag warning light.

If an accident has occurred, the control unit stores crash data and then locks itself.

Why does the control unit 68085880AH fail?

The most common cause on the 68085880AH is crash data from an earlier accident, even if no airbag was triggered. A normal diagnostic tool cannot erase this data. Further triggers include ageing electronics, cold solder joints, moisture and voltage spikes.

Airbag24 erases the crash data during the repair, and then the components are checked.

The other causes concern either the electronics themselves or their power supply. Corrosion at plug connections also belongs here, and voltage spikes arise, for example, with a weak battery or after a jump-start.

How can you tell that the 68085880AH is defective?

The airbag warning light in the instrument cluster lights up permanently or only intermittently. In addition, an error message appears in the instrument cluster. A defect on the 68085880AH can mean that airbags and seatbelt pretensioners may not trigger in an emergency.

Connection problems are added to this: the diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared.

As long as the light is on, a check is advisable.
