Airbag control unit with part number 68526670AB

What does the airbag control unit 68526670AB do?

The airbag control unit 68526670AB is the control unit of the restraint system (SRS) in Jeep. It checks the signals from the crash sensors and decides in an accident which airbags and seatbelt pretensioners are triggered.

It works within milliseconds and monitors the entire system at the same time. It shows faults via the airbag warning light in the instrument cluster, so that you notice malfunctions early.

After an accident, the unit stores crash data and locks itself afterwards. How the repair deals with this lock is described in the later sections.

Why does the control unit 68526670AB fail?

The most common cause is stored crash data after an accident, even when no airbag has deployed. Other causes lie in age, moisture and voltage spikes.

A normal diagnostic tool cannot erase crash data. Airbag24 erases it during the repair.

Further causes at a glance:

• ageing electronic components
• dry solder joints
• moisture and corrosion on plug connectors
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the 68526670AB is defective?

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

In this state, airbags and seatbelt pretensioners may not deploy in an emergency.

The warning light makes the fault clearly visible. Anyone who sees it lit should have the system checked promptly.
