Airbag control unit with part number P68186181AB

What does the airbag control unit P68186181AB do?

As the SRS control unit, the airbag control unit P68186181AB controls the restraint system of Chrysler. It evaluates the crash sensors, selects in an accident within milliseconds the airbags and seatbelt pretensioners to be triggered, and monitors the system permanently. After an accident it stores crash data and locks itself.

The unit reports faults via the airbag warning light, so that you can react early. Monitoring runs constantly in the background.

Why does the control unit P68186181AB fail?

Stored crash data from an accident is the most common cause in the control unit P68186181AB, even when no airbag has triggered. An ordinary diagnostic tool cannot erase it. Other causes are aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

The data remains in the memory even when no airbag has triggered. The other causes have nothing to do with an accident, because they concern ageing, contacts and the power supply. Such causes can only be narrowed down by measurement.

How can you tell that the P68186181AB is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and an error message appears in the instrument cluster. The diagnostic tool finds no connection to the control unit P68186181AB, or the fault memory cannot be cleared. Airbags and seatbelt pretensioners may then possibly not trigger in an emergency.

The warning light is the visible sign of a fault in the restraint system. If it appears, have the fault memory read out before you plan any further steps.
