Airbag control unit with part number 68490917AC

What does the airbag control unit 68490917AC do?

The airbag control unit 68490917AC is the central control unit of the restraint system (SRS) for Jeep. It evaluates the crash sensors, decides in an accident within milliseconds on the triggering of airbags and seatbelt pretensioners, and monitors the system continuously.

The device shows faults via the airbag warning light. Monitoring requires no action from you.

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

Why does the control unit 68490917AC fail?

The most common cause on the 68490917AC is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase it. Further causes are aged electronic components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes.

Voltage spikes can arise, for example, from a weak battery or a jump start. Plug connectors, in turn, are susceptible to moisture, which can cause corrosion.

Which of these causes is actually present is only shown by the examination of the unit.

How can you tell that the 68490917AC is defective?

A defect in the 68490917AC shows itself as an airbag warning light that lights up permanently or intermittently, as a fault message in the instrument cluster, as a missing connection to the diagnostic tool, or as a fault memory that cannot be cleared.

In an emergency, the airbags and seatbelt pretensioners may not be able to deploy. The light is therefore a reason to act promptly.

A check is sensible as soon as the display appears.
