Airbag control unit with part number P68164087AB

What does the airbag control unit P68164087AB do?

The airbag control unit P68164087AB is the main module of the restraint system in Dodge vehicles. It evaluates the crash sensors and, in an accident, determines within milliseconds which airbags and seatbelt pretensioners are triggered.

The system is monitored continuously. If the control unit detects a fault, the airbag warning light indicates it.

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

Why does the control unit P68164087AB fail?

Most often crash data is the cause, left stored in the unit after an accident, even if no airbag has deployed. A standard diagnostic tool cannot reach this data.

The data therefore stays stored even when nothing can be seen on the vehicle from outside.

Besides this there are aged electronic components, cold solder joints, and moisture and corrosion on the plugs. Voltage spikes, for example with a weak battery or a jump start, can also stress the control unit.

How can you tell that the P68164087AB is defective?

On the P68164087AB, you first notice a defect through the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Added to this are a fault message, a missing connection to the diagnostic tool, or a fault memory that cannot be erased.

If the light stays on, airbags and seatbelt pretensioners may fail to deploy in an emergency. This applies regardless of how the car seems in everyday use.
