Airbag control unit with part number 68226174AF

What does the airbag control unit 68226174AF do?

The airbag control unit 68226174AF is the central control unit of the restraint system (SRS) for Dodge. It evaluates the crash sensors, decides on the triggering of airbags and seatbelt pretensioners within milliseconds in an accident and monitors the system continuously. After an accident it stores crash data and locks itself.

The control unit reports faults via the airbag warning light in the instrument cluster. In addition, the fault is recorded in the memory so that a later test can find it.

Triggering depends on electronics that work cleanly and on intact wiring to the sensors and seatbelt pretensioners.

Why does the control unit 68226174AF fail?

Most often, stored crash data leads to the failure of the 68226174AF, even if no airbag has fired. Added to this are ageing components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data remains in the unit after an accident. A normal diagnostic tool does not make it disappear, whereas Airbag24 erases it during repair.

Electronics age, solder joints can go cold, and moisture causes corrosion on plug contacts.

Voltage spikes, for example from a weak battery or a jump start, add further strain to the electronics. You find the exact cause only through a test.

How can you tell that the 68226174AF is defective?

A defect in the 68226174AF is first noticed on the airbag warning light in the instrument cluster, which lights up permanently or intermittently. In that case the airbags and seatbelt pretensioners may not be able to deploy in a crash.

Pay particular attention to these signs:

• Airbag warning light on permanently or with interruptions
• Fault message in the instrument cluster
• Diagnostic tool cannot reach the control unit
• Fault memory remains, even after an attempt to clear it

The warning light reports the fault as soon as the system detects it. Before any repair, therefore, a test always comes first to establish whether the control unit, a connector or a cable is affected.

• Dodge Charger 7th generation (2011-2015)

If the label on the removed unit matches the part number on this page, it is the right type. Nevertheless, have the fault memory read out beforehand, because only the result shows whether the control unit is defective or whether a connector or cable is responsible for the fault.

For the same vehicles, we also repair control units with the part numbers 68226173AC, 68226173AD, 68226173AE, 68297875AA, 68297876AA, 68316744AA.

How does the repair of the 68226174AF work?

First have the fault memory read out and attach the log. Then disconnect the battery, remove the control unit, create the repair order online and send the unit in. Processing at Airbag24 takes 3–4 working days as a rule.

Airbag24 tests the unit on the test bench, repairs defective components, erases stored crash data and carries out a function test. After that the unit comes back to you.

This period applies exclusively to the work at Airbag24.

Our repairs come with 2 years' statutory liability for defects.

The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
