Airbag control unit with part number P68186182AD

What does the airbag control unit P68186182AD do?

The airbag control unit P68186182AD is the central control unit of the restraint system (SRS) in Chrysler. It evaluates the crash sensors, decides in an accident within milliseconds whether to trigger airbags and seatbelt pretensioners, and reports faults via the airbag warning light.

During operation the unit monitors the entire system continuously. If it detects a fault, it creates an entry in the fault memory, and the fault appears in the instrument cluster.

After an accident the control unit stores crash data and locks itself. This state also occurs after accidents in which no airbag was deployed.

Why does the control unit P68186182AD fail?

The most common cause is stored crash data after an accident, even if no airbag deployed. Other possible causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data cannot be erased with a standard diagnostic tool. If you have problems with the unit after an accident, look first at this stored data.

The other causes tend to develop gradually: electronic components age, solder joints change, and moisture can cause corrosion at plugs. Voltage spikes, by contrast, occur suddenly, for example when jump-starting.

How can you tell that the P68186182AD is defective?

Typical signs are an airbag warning light in the instrument cluster that stays on permanently or intermittently, a fault message in the instrument cluster, no connection between the diagnostic tool and the control unit, and a fault memory that cannot be cleared.

• Airbag warning light in the instrument cluster stays on permanently or intermittently
• Fault message in the instrument cluster
• The diagnostic tool gets no connection to the control unit
• The fault memory cannot be cleared

If any of these signs is present, airbags and seatbelt pretensioners may fail to deploy in an emergency. So do not carry on without thinking, but have the cause clarified promptly.
