Airbag control unit with part number 68355364AB

What does the airbag control unit 68355364AB do?

The airbag control unit 68355364AB manages the SRS restraint system in the Jeep. It receives the signals from the crash sensors, determines in a crash within milliseconds the triggering of airbags and seatbelt pretensioners, and monitors the system continuously. After an accident it stores crash data and locks itself.

The monitoring runs on every journey. Wiring, power supply and firing circuits are checked, and every fault goes into the fault memory.

You do not notice that the unit locks itself while driving. The result only shows when a diagnostic tool tries to address it.

Why does the control unit 68355364AB fail?

The most frequent cause is an accident whose crash data remains in the unit, even if no airbag has deployed; an ordinary diagnostic tool does not remove this data. Aged components, cold solder joints, moisture at plug connections and voltage spikes are also possible.

Crash data is the log of an event. It is stored regardless of whether a seatbelt pretensioner or an airbag actually fired.

Electronics age, and this also affects solder joints on the circuit board, which can break or lose contact over time.

Moisture and corrosion on the connectors worsen the connection. Voltage spikes, for example from a weak battery or a jump start, put additional strain on the components.

How can you tell that the 68355364AB is defective?

A defect shows through the airbag warning light in the instrument cluster staying on permanently or intermittently, a fault message in the instrument cluster, no connection between the diagnostic tool and the control unit, or a fault memory that cannot be cleared.

The airbag warning light in the instrument cluster is the clearest warning sign. It either stays on constantly or comes on at irregular intervals.

A fault message in the instrument cluster may also appear. If the diagnostic tool cannot be connected to the control unit, or the fault memory stays full despite an erase attempt, this is likewise a sign of a problem. Airbags and seatbelt pretensioners may then not deploy in an emergency, which is why a prompt check makes sense.
