Airbag control unit with part number P68148024AA

What does the airbag control unit P68148024AA do?

The P68148024AA is the airbag control unit for the restraint system (SRS) of Jeep. It constantly checks the crash sensors, seatbelt pretensioners and airbags, and in an accident calculates within milliseconds which of them are triggered. It reports faults via the airbag warning light.

The sensors are monitored continuously while the car is in operation. After an accident the unit stores crash data and locks itself.

Why does the control unit P68148024AA fail?

The most common cause at the P68148024AA is crash data stored after an accident, even if no airbag has triggered. Other causes come from the electronics and their surroundings.

Crash data remains stored, because a normal diagnostic tool does not erase it. Airbag24 removes it during the repair.

The other causes at a glance:

• aged components in the electronics
• cold solder joints
• wetness and rust at plug connections
• voltage spikes, for example from a jump start

How can you tell that the P68148024AA is defective?

You recognise a defect on the P68148024AA by the airbag warning light in the instrument cluster lighting up permanently or intermittently. This is accompanied by an error message in the instrument cluster. In an emergency, airbags and seatbelt pretensioners may then not trigger, and a diagnostic tool cannot find the control unit.

Even if the vehicle still drives, the light calls for a check. It shows the fault directly.
