Airbag control unit with part number 68526680AB

What does the airbag control unit 68526680AB do?

The airbag control unit 68526680AB is the central control unit of the restraint system (SRS) for Jeep. It evaluates the crash sensors, determines in the event of a crash which airbags and seatbelt pretensioners are triggered, and reports faults via the airbag warning light.

To do this, it checks the system continuously, because triggering must be correct within a fraction of a second. Without this monitoring, the state of the system would remain unknown.

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

Why does the control unit 68526680AB fail?

The most common cause with the 68526680AB is crash data that remains stored after an accident, even if no airbag has deployed. Other causes include aged components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

Crash data cannot be erased with a normal diagnostic tool. Repair is required for that, and during the repair Airbag24 removes it.

The other causes concern the electronics in everyday use. Components become weaker over the years, solder joints can go cold, and moisture and corrosion attack the plug connections.

Voltage spikes arise, for example, from a weak battery or when jump leads are connected.

How can you tell that the 68526680AB is defective?

On the 68526680AB, a fault first shows up at the airbag warning light in the instrument cluster, which lights up permanently or intermittently. A fault message there, a lack of connection to the diagnostic tool and a fault memory that cannot be cleared also indicate it.

In this state, airbags and seatbelt pretensioners may not be able to deploy in an emergency. That is why each of these indications is a reason to act promptly.

The light indicates the fault and so gives the first sign.

• Airbag warning light in the instrument cluster, permanently or intermittently
• Error message in the instrument cluster
• Diagnostic tool receives no connection
• Fault memory cannot be cleared
