Airbag control unit with part number P68335041AA

What does the airbag control unit P68335041AA do?

The airbag control unit P68335041AA analyses the signals from the crash sensors in the restraint system (SRS) of Dodge. In an accident it decides which airbags and seatbelt pretensioners are triggered, and it monitors the system constantly.

Faults that it finds are passed on via the airbag warning light in the instrument cluster.

After an accident, it stores crash data and locks itself. The unlocking takes place during the repair.

Why does the control unit P68335041AA fail?

Crash data stored in the control unit after an accident is the most common cause, even without an airbag having fired. Added to this are aged components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes. The P68335041AA is examined specifically for these points during testing.

The deletion does not succeed with a normal diagnostic tool; Airbag24 carries it out during the repair.

The other causes concern the electronics and their connections. Components age, solder joints go cold, and moisture attacks contacts. Voltage spikes arise, for example, from a weak battery.

How can you tell that the P68335041AA is defective?

A defect in the P68335041AA can be recognised by the airbag warning light in the instrument cluster, which lights up constantly or intermittently.

• Airbag warning light lights up constantly or intermittently
• Fault message in the instrument cluster
• Diagnostic tool does not establish a connection to the control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may possibly fail to deploy. If these signs appear, have the system checked promptly.
