Airbag control unit with part number P68185856AB

What does the airbag control unit P68185856AB do?

The airbag control unit P68185856AB is the central control unit of the restraint system (SRS) in Jeep. It constantly checks the crash sensors, decides in an accident within milliseconds on the triggering of airbags and seatbelt pretensioners, and reports faults via the airbag warning light.

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

The sensor data is evaluated in the background while you drive the vehicle normally.

Why does the control unit P68185856AB fail?

The most common cause is crash data stored after an accident, even without a triggered airbag. A normal diagnostic tool cannot erase it. Aged electronics, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes are also possible causes.

The repair at Airbag24 erases this crash data, so you do not need to do anything about it beforehand.

Aged components and cold solder joints cannot be seen from outside. Voltage spikes arise, for example, from a weak battery or jump-starting.

How can you tell that the P68185856AB is defective?

The airbag warning light in the instrument cluster lights up constantly or only at times. In addition, a fault message appears in the instrument cluster, and the diagnostic tool finds no connection to the control unit. The fault memory also cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then not deploy.

Have the system checked promptly.
