Airbag control unit with part number 68398610AB

What does the airbag control unit 68398610AB do?

The airbag control unit 68398610AB is the central control unit of the restraint system in Jeep. It evaluates the crash sensors and determines in a crash within milliseconds which airbags and seatbelt pretensioners fire, while continuously monitoring the system.

The unit shows faults in the system via the airbag warning light in the instrument cluster. In this way, the condition of the restraint system stays in view.

A crash causes the unit to store crash data and lock itself.

Why does the control unit 68398610AB fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase this data. Other causes are ageing, moisture and corrosion, as well as voltage spikes.

Airbag24 erases the crash data during the repair, not the driver.

The other causes include, among others:

• Ageing electronic components
• Cold solder joints
• Moisture and corrosion at plug connections
• Voltage spikes from a weak battery or jump-starting

How can you tell that the 68398610AB is defective?

A defect shows up through the airbag warning light, an error message in the instrument cluster, a missing connection to the diagnostic tool, or a fault memory that cannot be cleared. The light may stay on permanently or flash on intermittently.

As long as these signs persist, airbags and seatbelt pretensioners may fail to deploy in an emergency. This applies to the entire system, not just to individual triggers.

A prompt check is therefore advisable, even if the car runs normally in everyday use.
