Airbag control unit with part number P68185860AA

What does the airbag control unit P68185860AA do?

The airbag control unit P68185860AA controls the restraint system (SRS) of Jeep. It processes the signals from the crash sensors and decides in a crash, within fractions of a second, which airbags and seatbelt pretensioners are triggered.

In addition, it checks the function of the connected components during operation. If it detects a fault, it switches on the airbag warning light in the instrument cluster so that the driver notices the fault.

After a crash, the control unit stores crash data and locks itself.

Why does the control unit P68185860AA fail?

Crash data stored after a crash is the most common cause of faults in the P68185860AA, even if no airbag has deployed. Aged components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes are also possible causes.

A normal diagnostic tool cannot remove this crash data. Airbag24 deletes it during the repair.

Further causes include aged electronic components, cold solder joints, and moisture and corrosion on plug connections. Voltage spikes, for example from a weak battery or a jump start, can also disturb the unit. Only the examination of the unit shows whether one of these causes is present.

How can you tell that the P68185860AA is defective?

A defect in the P68185860AA shows first through the airbag warning light in the instrument cluster. Further irregularities that appear during testing come on top of this.

• The airbag warning light stays on permanently or comes on only intermittently.
• An error message appears in the instrument cluster.
• The diagnostic tool cannot connect to the control unit.
• The fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then be unable to deploy. A prompt check therefore clarifies whether the control unit is affected.
