Airbag control unit with part number P68293703AA

What does the airbag control unit P68293703AA do?

The airbag control unit P68293703AA controls the restraint system (SRS) of Jeep. It checks the signals from the crash sensors and decides within milliseconds which airbags and seatbelt pretensioners to trigger in an accident. It indicates faults via the airbag warning light.

In everyday use, monitoring runs in the background and checks the entire system continuously. After an accident the unit stores crash data and then locks itself.

Why does the control unit P68293703AA fail?

The most common cause is crash data stored after an accident, even if no airbag was deployed; a normal diagnostic tool cannot erase it. Other causes include aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes, for example from a weak battery or jump-starting.

Crash data remains stored in the control unit even if no airbag was deployed. A conventional diagnostic tool cannot remove it.

The other causes lie in the electronics or their surroundings. Components age, solder joints can turn cold, and moisture attacks plug connectors. Voltage spikes when starting with external power can also damage the electronics.

How can you tell that the P68293703AA is defective?

A defect shows up at the airbag warning light in the instrument cluster, which lights continuously or intermittently, or as a fault message in the instrument cluster. In addition, the diagnostic tool cannot establish a connection to the control unit, and the fault memory cannot be cleared. In this case, airbags and seatbelt pretensioners may fail to deploy in an emergency.

Typical signs at a glance:

• The airbag warning light stays on permanently or flickers intermittently.
• A fault message appears in the instrument cluster.
• The diagnostic tool cannot find the control unit.
• The fault memory cannot be cleared.

The warning light itself indicates the defect. You should therefore not ignore the display.
