Airbag control unit with part number P68186647AA

What does the airbag control unit P68186647AA do?

In the restraint system (SRS) of Jeep, the airbag control unit P68186647AA controls the triggering of the airbags and seatbelt pretensioners. The signals from the crash sensors converge there, and the decision is made within milliseconds. After an accident the unit stores crash data and locks itself.

At the same time it checks the connected components and their wiring, and it shows faults via the airbag warning light.

Why does the control unit P68186647AA fail?

The most common cause is the crash data stored after an accident, even if no airbag fired. Furthermore, aged components, moisture on the plugs and voltage spikes can bring about the failure of the P68186647AA.

Crash data cannot be erased with a normal diagnostic tool, so the unit keeps showing the fault. Damage over time is also possible. Electronic components age, and solder joints can become cold, which looks like a failure.

Moisture and corrosion at plug connections as well as voltage spikes, for example when starting with external power, round out the picture.

How can you tell that the P68186647AA is defective?

Typical signs are an airbag warning light that lights up permanently or intermittently, an error message in the instrument cluster, or a diagnostic tool with no connection to the control unit P68186647AA. A fault memory that cannot be erased also belongs here. In an emergency, airbags and seatbelt pretensioners may then possibly not trigger.

These signs are noticeable:

• Airbag warning light on permanently or intermittently
• Error message in the instrument cluster
• Diagnostic tool with no connection to the control unit
• Fault memory that cannot be erased

Take such signs seriously. Have the fault memory read out so that it is clear where the fault lies.
