Airbag control unit with part number 68263739AA

What does the airbag control unit 68263739AA do?

The airbag control unit 68263739AA is the central control unit of the restraint system (SRS) for Dodge. It evaluates the signals from the crash sensors, decides within milliseconds in a crash whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. It reports detected faults via the airbag warning light.

The unit processes the sensor readings without interruption and checks the wiring to the trigger units. This keeps the system ready for use in an emergency.

After a crash, the control unit stores crash data and locks itself.

Why does the control unit 68263739AA fail?

Stored crash data is the most common cause, even if no airbag has deployed. Other possible causes are aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

Crash data cannot be erased with a standard diagnostic tool. The fault therefore remains until Airbag24 erases the data during the repair.

Aged electronic components gradually lose reliability, and cold solder joints can come loose. Moisture and corrosion attack the contacts at plug connectors.

Voltage spikes occur, for example, with a weak battery or after a jump start.

How can you tell that the 68263739AA is defective?

The airbag warning light lights up permanently or intermittently, a fault message appears in the instrument cluster, the diagnostic tool cannot connect to the control unit, and the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

• The airbag warning light stays on permanently or intermittently.
• A fault message appears in the instrument cluster.
• The diagnostic tool finds no connection to the control unit.
• The fault memory cannot be cleared.

The warning light is the clearest indication, and you should not ignore the display.

Only the evaluation of the fault memory shows whether the control unit itself is affected.
