Airbag control unit with part number 68211617AA

What does the airbag control unit 68211617AA do?

The control unit 68211617AA forms the central control of the SRS restraint system for Chrysler. It reads the crash sensors and, in an accident, decides within milliseconds which airbags and seatbelt pretensioners are triggered.

The system is monitored constantly during operation. If a fault is detected, the airbag warning light in the instrument cluster shows it.

After an accident, the unit stores crash data and locks itself.

Why does the control unit 68211617AA fail?

On the 68211617AA, the most common cause after an accident is stored crash data, even if no airbag has deployed; a normal diagnostic tool does not erase it. Other causes are aged electronic components, cold solder joints, moisture and corrosion, and voltage spikes.

Crash data is also created in accidents where no airbag deploys. It remains stored in the unit.

A control unit is exposed to constant stress. The other causes at a glance:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or jump-starting

How can you tell that the 68211617AA is defective?

A defect in the 68211617AA becomes visible through the displays in the instrument cluster. The diagnosis can also fail because of it.

These signs occur individually or together:

• airbag warning light 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 erased

In an emergency, airbags and seatbelt pretensioners may fail to trigger. A prompt inspection is therefore advisable.
