Airbag control unit with part number 68263743AB

What does the airbag control unit 68263743AB do?

The airbag control unit 68263743AB controls the restraint system (SRS) in Dodge. It evaluates the signals from the crash sensors, decides in a crash within fractions of a second whether to trigger, and monitors the system continuously.

The unit detects faults itself; they are indicated via the airbag warning light in the instrument cluster.

After a crash, it stores crash data and locks itself.

Why does the control unit 68263743AB fail?

Most often these are crash data from an accident, even if no airbag triggered. A normal diagnostic tool cannot erase them. Other causes are aging electronics, moisture, cold solder joints and voltage spikes.

Crash data arise not only when airbags are triggered but also in accidents where nothing was triggered. If you want to narrow down the cause, you cannot avoid the fault memory.

Voltage spikes arise, for example, from a weak battery or when connecting jump leads. Solder joints can be cold, and plug connections corrode in moisture.

How can you tell that the 68263743AB is defective?

The airbag warning light stays on or lights up intermittently while the instrument cluster reports faults. A defect also shows through connection problems with the diagnostic tool. In an emergency, airbags and seatbelt pretensioners may then not trigger.

• Airbag warning light that is on constantly or intermittently
• Fault message in the instrument cluster
• Diagnostic tool without connection to the control unit
• Fault memory that cannot be cleared

The light reports the defect directly in the vehicle, so react to it promptly.

Whether the control unit or the wiring is affected only the diagnosis will show.
