Airbag control unit with part number P68164087AA

What does the airbag control unit P68164087AA do?

The airbag control unit P68164087AA controls the restraint system (SRS) of Dodge. It reads the signals from the crash sensors and, in an accident within milliseconds, determines which airbags and seatbelt pretensioners are triggered. If it detects a fault, it indicates it via the airbag warning light.

The control unit monitors the system continuously. After an accident it stores crash data and locks itself.

Why does the control unit P68164087AA fail?

The most common cause is stored crash data from an accident, even if no airbag has deployed. A normal diagnostic tool does not erase it. Further triggers are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Airbag24 erases the crash data during the repair. Voltage spikes arise, for example, from a weak battery or a jump start, and ageing affects the electronics over the years.

Which cause applies in an individual case only becomes clear during the inspection.

How can you tell that the P68164087AA is defective?

The signs are the airbag warning light in the instrument cluster, a fault message, or a diagnostic tool without connection to the control unit. A fault memory that cannot be cleared also indicates a defect.

• airbag warning light in the instrument cluster lights up permanently or intermittently
• fault message in the instrument cluster
• diagnostic tool gets no connection to the control unit
• fault memory cannot be cleared

If any of these signs is present, airbags and seatbelt pretensioners may not be able to deploy in an emergency. The light indicates the fault, so you should have it checked promptly.
