Airbag control unit with part number P68186180AB

What does the airbag control unit P68186180AB do?

The airbag control unit P68186180AB controls the restraint system (SRS) of Dodge. In an impact, it evaluates the crash sensors and decides within milliseconds which airbags and seatbelt pretensioners are triggered.

During operation, the unit monitors the components of the system. It indicates faults via the airbag warning light in the instrument cluster.

After an accident, it stores crash data and then locks itself. This also happens when no airbag has deployed at all.

Why does the control unit P68186180AB fail?

Stored crash data after an accident is the most common cause of faults on the P68186180AB, even if no airbag has deployed. Ordinary diagnostic tools cannot erase it.

Airbag24 removes the crash data as part of the repair. Other causes are aged electronic components, cold solder joints, and moisture and corrosion at plug connections.

Voltage spikes, for example from a weak battery or jump-starting, can also lead to failures.

How can you tell that the P68186180AB is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently as soon as the P68186180AB has stored a fault. In addition, the instrument cluster shows an error message, and the diagnostic tool gets no connection.

The fault memory cannot then be erased, which calls for an inspection. In an emergency, airbags and seatbelt pretensioners may possibly fail to trigger.

It makes sense to have these signs checked promptly.
