Airbag control unit with part number P68068701AB

What does the airbag control unit P68068701AB do?

In the Jeep vehicle, the airbag control unit P68068701AB is the central control unit of the restraint system (SRS). It evaluates signals from the crash sensors, decides in an accident which airbags and seatbelt pretensioners are triggered, and constantly checks the system for faults.

If the system reports a fault, the airbag warning light in the instrument cluster comes on.

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

Why does the control unit P68068701AB fail?

Crash data from an accident is the most common cause for the P68068701AB, even if no airbag has deployed. A normal diagnostic tool cannot erase this data, but Airbag24 erases it during the repair. Other possible causes are aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

The unit logs the data regardless of what the incident meant for the airbags.

The other causes concern the electronics and their connections. Solder joints can go cold, components age, and moisture promotes corrosion at plug connections.

Strong voltage spikes, for example from a weak battery or a jump start, put additional strain on the control unit.

How can you tell that the P68068701AB is defective?

You recognise a fault on the P68068701AB by the airbag warning light, which may stay on permanently or intermittently. A fault message in the instrument cluster appears as well. In addition, the diagnostic tool cannot establish a connection, and the fault memory cannot be cleared.

Such an indication is a clear signal, even if the vehicle otherwise seems unremarkable.

In an emergency, airbags and seatbelt pretensioners may fail to deploy, so a prompt check is advisable.
