Airbag control unit with part number 68105510AA

What does the airbag control unit 68105510AA do?

The 68105510AA is the airbag control unit for the restraint system (SRS) of Chrysler. It processes the signals from the impact sensors and decides within milliseconds in a crash about airbags and seatbelt pretensioners.

It monitors the system continuously and reports faults via the airbag warning light. After an accident it stores crash data and locks itself.

Why does the control unit 68105510AA fail?

Stored crash data from an accident is the most common cause, even if no airbag has deployed. Further possible causes are ageing components, cold solder joints, moisture at plug connections and voltage spikes.

This crash data cannot be cleared with a normal diagnostic tool. Airbag24 removes it during the repair.

The other causes concern the electronics itself or its surroundings. Solder joints can go cold, corrosion attacks plugs, and voltage spikes arise, for example, with a weak battery or a jump start.

How can you tell that the 68105510AA is defective?

A defect shows up as the airbag warning light in the instrument cluster lighting up permanently or intermittently. In addition an error message appears, the diagnostic tool connects to the control unit with difficulty, and the fault memory remains.

Typical signs:

• Airbag warning light lights up permanently or comes on intermittently
• Error message in the instrument cluster
• Diagnostic tool receives no connection to the control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may fail to deploy. Anyone who notices one of these signs should have the fault checked.
