Airbag control unit with part number 6590002FA1

What does the airbag control unit 6590002FA1 do?

The airbag control unit 6590002FA1 coordinates the restraint system (SRS) in Xpeng. It processes the readings from the crash sensors and, within fractions of a second, determines which airbags and seatbelt pretensioners fire in an accident. After an accident, it keeps crash data in memory and locks itself.

During the day the control unit runs unobtrusively. It checks the supply voltage, the connected sensors and the igniters, so the system is ready for use at all times.

If the check finds a fault, it is stored and made visible via the airbag warning light. Airbag24 erases the crash data as part of the repair.

Why does the control unit 6590002FA1 fail?

The most common cause is the crash data stored after an accident, even if no airbag has deployed, and a normal diagnostic tool cannot remove it. Other causes include ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or a jump start.

This entry remains even when the vehicle drives normally again afterwards. It is therefore not a sign that something is wrong at the moment.

The other causes tend to develop gradually. Ageing components and cold solder joints cause changing faults, while moisture and corrosion attack plug connections over time.

Voltage spikes also stress the electronics. A weak battery or an improper jump start can change the on-board voltage sharply for a short time.

How can you tell that the 6590002FA1 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and a fault message appears in the instrument cluster. In addition, the diagnostic tool cannot establish a connection to the control unit, and the fault memory cannot be cleared.

The airbag warning light in the instrument cluster is the clearest warning sign. It stays on permanently or only comes on from time to time.

A fault message may also appear on the display. If establishing a connection to the diagnostic tool fails as well, that also points to a problem in the system.

In an emergency, airbags and seatbelt pretensioners may not deploy, so a check should be carried out promptly.

Check the part number on the label of the removed unit against this page. This only makes sure that you have the correct unit in front of you.

Have the fault memory read out beforehand. The result shows whether the control unit is faulty or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 0 285 021 183.

How does the repair of the 6590002FA1 work?

First have the fault memory read out and enclose the log, then disconnect the battery and remove the control unit 6590002FA1. Then create a repair order online and send the unit in packed. Processing at Airbag24 usually takes 3–4 working days.

Airbag24 checks the unit on the test bench, replaces defective components, erases the stored crash data and carries out a function test. The unit you sent in then comes back to you.

The order of the first steps is important, because the removal may only take place after the battery has been disconnected.

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 6590002FA1 get to Airbag24?

You send the unit as a parcel or, for a UPS collection for an extra charge, book one. After the repair, Airbag24 returns it to you by UPS.

Put the printed repair order into the parcel and pack the control unit shockproof.
