Airbag control unit Fiat 500 was broken. Hard to believe but they can really repair it! Recommendation!!
Automatically translated · Original: German
From the first phone call, the order processing, to the shipping, everything was done very quickly and professionally. Now I still have to send the repaired unit to the Swedish workshop and then hopefully the Honda can finally pass the HU there again (failed because of the red airbag light). Thanks to Airbag 24 in Berlin 👍👏. Gerd

What is a Volkswagen California T4 airbag control unit?
In the Volkswagen California T4, the airbag control unit acts as the master control unit of the restraint system (SRS). It evaluates what the crash sensors report and, in an accident, decides within milliseconds which airbags and seatbelt pretensioners fire. In addition, it continuously monitors the condition of the system and indicates faults with the airbag warning light.
It is installed in the Volkswagen California T4 (1990 to 2003); the unit is made by Bosch. If an accident occurs, it stores crash data and locks itself.
In normal operation you notice nothing of this. The unit only becomes conspicuous when the warning light comes on or the fault memory shows entries. Then it is worth having the control unit checked.
Why is the Volkswagen California T4 airbag control unit defective?
Most often the cause is crash data left in the unit after an accident, even if no airbag deployed; an ordinary diagnostic tool cannot remove it. Other possible causes are aged components, cold solder joints, moisture at connectors and voltage spikes.
Electronics age: components lose their values over the years, solder joints develop cracks, and corrosion sets in on connectors once moisture gets in. Voltage spikes, for example from a weak battery or from jump-starting, can also damage the unit. Such defects usually develop slowly and only become noticeable when the self-diagnosis fails.
Signs of a defect are an airbag warning light that stays on permanently, a fault memory that you cannot clear, or a diagnostic tool with no connection to the control unit. Do not ignore the light: with a fault present, it is not certain that the airbags will deploy in an emergency.
Common error codes for Volkswagen California T4 airbag control unit repair
The codes in the Volkswagen California T4 concern different parts of the system: the control unit itself with its memory, the supply voltage, the squib circuits of the airbags and stored crash data. Which code is stored in your case is shown by reading it out with a diagnostic tool.
An entry may refer to the control unit itself, for example an internal memory fault. It may equally concern the power supply or a squib circuit, that is the wiring together with the igniter of a front, passenger or side airbag. There are also messages that merely record that an impact was detected. The list shows codes that can occur with this unit.
- 65535 → Internal memory fault in the control unit
- B2013 → Control unit fault, not further specified
- 00595 → Crash data stored, impact detected
- 01226 → Crash data stored, driver airbag affected
- 00532 → Supply voltage outside the permitted range
- 00588 → Driver airbag squib circuit: resistance out of range or short circuit
- 00589 → Passenger airbag squib circuit: resistance too high
- 01217 → Side airbag squib circuit, driver side: circuit fault
The codes are read with a diagnostic tool. A code alone does not necessarily mean that the control unit is defective, since connectors, wiring or an airbag module are just as likely causes. Only the check shows where the fault lies.
What part numbers are available for the Volkswagen California T4 airbag control unit repair?
On the label of the airbag control unit you will find the part number, which defines the exact version. In the Volkswagen California T4, different numbers are in circulation depending on equipment and year of manufacture.
The list below shows known part numbers for this vehicle; it is not complete.
- 1J0 909 603 AH (Bosch)
- 6N0 909 603 S (Bosch)
Compare the number of your unit with this list. This only ensures that it is the right unit. Whether it is defective is clarified only by reading out the fault memory or by the check.
The path to repair: have the fault memory read out, disconnect the battery and remove the control unit. Then you create a repair order online and send in the unit. Airbag24 usually needs 3–4 working days for checking, repairing and testing. 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.
