Airbag control unit with part number P68148042AA

What does the airbag control unit P68148042AA do?

The airbag control unit P68148042AA coordinates the restraint system (SRS) for vehicles of the Jeep brand. It evaluates the crash sensors, determines in an accident within milliseconds which airbags and seatbelt pretensioners deploy, and monitors the system continuously. It reports faults via the airbag warning light.

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

During operation it also keeps the fault memory, which can be read out with the diagnostic tool.

Why does the control unit P68148042AA fail?

The cause on the P68148042AA is most often crash data stored after an accident, even if no airbag has deployed. Normal diagnostic tools do not erase it. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data is only evident when it is read out, because no airbag has to have deployed for it to be stored.

Aged components and corrosion act over a longer period, whereas voltage spikes act suddenly, for example when starting with a weak battery.

How can you tell that the P68148042AA is defective?

A defect on the P68148042AA shows up as the airbag warning light in the instrument cluster, as fault messages and as a missing connection to the diagnostic tool.

• Airbag warning light on, permanently or intermittently
• Fault message in the instrument cluster display
• Diagnostic tool gets no connection to the control unit
• Fault memory cannot be emptied even after an attempt to erase it

In this state, airbags and seatbelt pretensioners may not deploy in an emergency.

It is worth taking the warning seriously, because the light shows the state of the system directly.
