Airbag control unit with part number 68263739AB

What does the airbag control unit 68263739AB do?

The airbag control unit 68263739AB is the central control unit of the restraint system (SRS) in Dodge. It processes the signals from the crash sensors and, in a crash, triggers the appropriate airbags and seatbelt pretensioners within milliseconds. After an accident it stores crash data and locks itself; only the repair lifts the lock.

In addition, it continuously checks its circuits and the connected sensors. Any faults found are stored in the fault memory.

Why does the control unit 68263739AB fail?

The most common cause is stored crash data, even when no airbag has deployed. You cannot access it with the usual diagnostic tools. Other causes, briefly summarised, are the following:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

Which of these causes applies in an individual case can only be established by testing.

How can you tell that the 68263739AB is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently when something in the system is wrong. In addition, fault messages appear in the instrument cluster, the diagnostic tool loses contact with the control unit, and the fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may therefore fail to deploy. This is not a detail to be sorted out in passing, but a warning about the safety function. You should therefore have the warning checked promptly.

Before removal, first compare the part number on the label of the unit with this page. This only establishes that the unit is the correct one, not whether it is defective. You should therefore also have the fault memory read out, as this is the only way to show whether the control unit or a plug or cable is the cause.
