Airbag control unit with part number 68357571AC

What does the airbag control unit 68357571AC do?

The airbag control unit 68357571AC controls the restraint system (SRS) of Jeep. It evaluates the signals from the crash sensors, decides in an accident within milliseconds about triggering airbags and seatbelt pretensioners, and monitors the system continuously. After an accident it stores crash data and locks itself.

Faults are reported via the airbag warning light in the instrument cluster. Monitoring runs continuously in the background.

Because the unit triggers airbags and seatbelt pretensioners directly, any fault affects the entire restraint system.

Why does the control unit 68357571AC fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump start.

The crash data remains in the unit's memory until it is erased. The entry stays in place even when no airbag has deployed.

Aged components, cold solder joints and corrosion at the contacts develop over time. Moisture accelerates this process at the plug connections.

Voltage spikes additionally stress the electronics and are taken into account in the examination.

How can you tell that the 68357571AC is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, a fault message appears in the instrument cluster, the diagnostic tool finds no connection to the control unit, or the fault memory cannot be cleared. Then airbags and seatbelt pretensioners may fail to deploy in an emergency.

The light shows the defect directly and is the first indication in the vehicle. A fault message in the instrument cluster confirms it additionally.

A diagnostic tool shows whether the control unit is reachable and which entries are in the fault memory.
