Airbag control unit with part number 68630142AB

What does the airbag control unit 68630142AB do?

As an SRS control unit, the airbag control unit 68630142AB controls the restraint systems of Jeep. It reads the crash sensors, determines in a crash within milliseconds which airbags and seatbelt pretensioners are triggered, and checks the system continuously. It reports faults via the airbag warning light.

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

This check runs in the background throughout the entire journey.

Why does the control unit 68630142AB fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. A normal diagnostic tool cannot erase it. In addition, aged components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes come into question for 68630142AB.

Other causes at a glance:

• Ageing electronic components
• Cold solder joints
• Moisture and corrosion on plug connections
• Voltage spikes, for example from a weak battery or a jump start

Which fault is present is only shown by reading out the fault memory.

How can you tell that the 68630142AB is defective?

A defect on the control unit 68630142AB is recognised by the airbag warning light in the instrument cluster when it lights up permanently or intermittently. A fault message in the instrument cluster, no connection of the diagnostic tool or a fault memory that cannot be cleared are further signs. In an emergency the airbags and seatbelt pretensioners may then fail to deploy.

The light is part of the vehicle's display system and shows faults in the restraint system directly.

The fault message only states that a fault is present; the cause is shown only by reading out the fault memory.
