Airbag control unit with part number P68148037AD

What does the airbag control unit P68148037AD do?

The airbag control unit P68148037AD controls the restraint system (SRS) of Jeep. It evaluates the signals from the crash sensors, determines in a collision within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After an accident it stores crash data and locks itself.

The unit indicates faults via the airbag warning light in the instrument cluster. Monitoring runs in the background for as long as the vehicle is in operation.

In the vehicle the control unit works together with sensors, wiring and the display. A fault in any of these parts can therefore show up in the control unit.

Why does the control unit P68148037AD fail?

The most common cause in the P68148037AD control unit is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase this data. Other possible causes include aged components, cold solder joints, moisture and voltage spikes.

The crash data is held in the memory of the unit, and the fault indication remains visible until the unit has been repaired. The other causes concern mainly the electronics and their connections. Aged components and corrosion at plug connectors can trigger faults, and voltage spikes, for example from a weak battery or a jump start, place additional strain on the circuitry.

How can you tell that the P68148037AD is defective?

The airbag warning light in the instrument cluster lights up on the P68148037AD control unit permanently or intermittently as soon as a fault is present. A fault message also appears in the instrument cluster. If the diagnostic tool cannot connect to the control unit and the fault memory cannot be cleared, airbags and seatbelt pretensioners may not trigger in an emergency.

The light therefore indicates that the system has detected a fault. Only the check of the fault memory reveals which cause lies behind it.
