Airbag control unit with part number 68437715AC

What does the airbag control unit 68437715AC do?

The airbag control unit 68437715AC coordinates the airbags and seatbelt pretensioners in the restraint system (SRS) of Jeep. It checks the crash sensors constantly and, in an impact, decides which components are triggered within milliseconds.

If the system reports a fault, the airbag warning light in the instrument cluster shows it. After an accident, the control unit keeps the crash data in memory and locks itself.

The control unit is therefore the junction between sensors and triggering.

Why does the control unit 68437715AC fail?

Crash data from an earlier accident is the most common cause with the 68437715AC, even if no airbag has triggered. Aged electronics, cold solder joints, moisture with rust on plug connectors and voltage spikes come on top of this.

Stored crash data remains if only a standard diagnostic tool is used. Airbag24 removes it during repair.

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

How can you tell that the 68437715AC is defective?

A defect on the 68437715AC shows up through the airbag warning light in the instrument cluster, which lights up permanently or intermittently, through a fault message in the instrument cluster and through missing communication with the diagnostic tool. In addition, the fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then fail to trigger, and that is exactly what the warning light points to.

Anyone who notices these signs should have the fault memory read out before any components are removed.
