Airbag control unit with part number P68233022AA

What does the airbag control unit P68233022AA do?

The airbag control unit P68233022AA coordinates the restraint system (SRS) of Fiat as the central unit. It measures accelerations via the crash sensors, evaluates them and decides which airbags and seatbelt pretensioners are triggered in an accident.

The electronics check the system continuously for faults. If they detect one, the airbag warning light in the instrument cluster lights up.

After an accident the control unit stores crash data and locks itself.

Why does the control unit P68233022AA fail?

The most common cause of the P68233022AA is stored crash data after an accident, even if no airbag was deployed. Ageing electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes are also possible.

Stored crash data cannot be erased with a normal diagnostic tool. Airbag24 erases them during repair.

Moisture and corrosion impair the contact at plugs, and cold solder joints can come loose. Voltage spikes arise, for example, from a weak battery or when a jump start is connected.

How can you tell that the P68233022AA is defective?

The airbag warning light in the instrument cluster indicates a defect in the P68233022AA when it stays on permanently or intermittently.

The warning light is the most important sign of a defect in the restraint system. As long as it is lit, airbags and seatbelt pretensioners may fail to deploy in an emergency.

These further signs also occur:

• error message in the instrument cluster
• diagnostic tool without connection to the control unit
• fault memory cannot be cleared

Comparing the part number on the label of the removed unit with this page only confirms that it is the right unit. Whether the unit is defective or a plug or cable is the cause is shown only by reading out the fault memory. Therefore have it read out beforehand.

For the same vehicles, we also repair control units with the part numbers 51782985, 51870005, 51897810, 51918659, 51963734, 519637734.

How does the repair of the P68233022AA work?

For the repair of the P68233022AA, you first read out the fault memory and enclose the log. Then you disconnect the battery, only then remove the control unit and create a repair order online.

You pack the well-packed unit and send it in. Airbag24 checks it on the test bench, finds defective components and repairs them. Afterwards stored crash data are erased and a function test is carried out.

Processing takes 3–4 working days. Afterwards your own unit goes back to you. 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 P68233022AA get to Airbag24?

You send the control unit P68233022AA in as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 returns it by UPS.

Put the printed repair order into the parcel and pack the unit shock-proof.
