Airbag control unit with part number P68148052AC

What does the airbag control unit P68148052AC do?

The airbag control unit P68148052AC is responsible for the restraint system (SRS) in the Dodge. It receives the signals from the crash sensors, decides in the event of an accident within milliseconds on airbags and seatbelt pretensioners, and checks the system continuously.

If it detects a fault, it indicates this via the airbag warning light in the instrument cluster.

After an accident it creates crash data and then locks itself.

Why does the control unit P68148052AC fail?

Crash data stored after an accident is the most common cause, even if no airbag has deployed. It cannot be erased with a normal diagnostic tool. Other causes are ageing, moisture and voltage spikes.

• aged electronic components
• cold solder joints
• moisture and corrosion at the plug connections
• voltage spikes, for example with a weak battery or jump start

Crash data in particular does not show up in a purely visual inspection. A targeted read-out is therefore part of the fault-finding.

How can you tell that the P68148052AC is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. There may also be an error message, a diagnostic tool without connection to the control unit or a fault memory that cannot be cleared.

Do not assume the problem will resolve itself. The warning light must be taken seriously.

In an emergency, airbags and seatbelt pretensioners may then possibly not trigger.

Compare the part number of the removed unit with this page, so that you can be sure it is the matching unit. Also have the fault memory read out beforehand, because only this log shows whether the control unit or a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 56054100AA, 56054100AB, 56054100AC, 56054100AD, 68029112AA, 68029112AB.

How does the repair of the P68148052AC work?

First have the fault memory read out and enclose the log. Then disconnect the battery, remove the control unit, create a repair order online and send in the well-packed unit.

Airbag24 tests the unit on the test bench, replaces defective components, erases the stored crash data and runs a function test. The own unit then comes back to you.

Checking, repairing and testing takes 3–4 working days at Airbag24 as a rule. The order of the first steps is mandatory for safety reasons, so nothing may be removed before the log and the disconnected battery are in place. 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.

How does the control unit P68148052AC get to Airbag24?

Either you send the unit in as a parcel, or you book a UPS collection for an extra charge. Airbag24 then sends the own, repaired unit back to you by UPS.

Enclose the printed repair order with the parcel and pack the control unit shockproof.
